Jeep - Wrangler :: 2006 - Getting Check Engine Light - Electrical Malfunction?
Oct 14, 2012
I am having a “Check Engine” light problem on a stock 06, 4 cylinder Jeep Wrangler with manual transmission. A local highly regarded independent mechanic has had it in his shop 3 or 4 times for more than a day each time. On the first visit he replaced a purge solenoid valve and reset the light. It stayed off for more than 400 miles and then relit. He went over it and checked the wires and connections and reset the light. Again it stayed off for some time and then relit. He has checked the Jeep site.
After the last visit he suggested I drive it and see if it would reset itself as it had been doing in the past. It did reset itself twice but it only stayed off for 10 miles the first time and 2 the second. The code indicates an electrical problem and he is now planning to drop the fuel tank and check the wires and sensors there. The next step may be an ECM transplant. This is only an emission system problem and the mechanic says it is OK to drive. We do not have emission inspections here. How important is it to fix the problem?

So this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.

2 days after replacing a weak battery during a cold snap the engine light came on. 2 days prior to replacement the gas cap warning and engine light came on, but immediately after the installation both warnings went off. Only the engine light came back on 2 days later. I have driven the Jeep 3 times since for about 20 miles total. Total mileage, 18,200. What the cause may be and how to proceed?

I have a 2000 Jeep Wrangler, manual transmission, 6-cylinder. I accidentally let the battery die in September. I got a jump, and it was fine until we got a cold snap. (We live in NJ.) On the first cold day (October), the battery was dead again. The battery is about 4 years old. I got it jumped, and it was fine, but the CE light came on. I have been dealing with the CE light and generally lousy engine performance ever since. (The car is lurching and hiccuping.) I have had it to the shop four times since the initial dead battery in September.
I bring it to the shop, they hook it up to the computer, and each time it indicates a sensor problem. They have replaced the 02 sensor, the TPS sensor, cleaned the throttle body, replaced several spark plugs, and swapped out the clockspring. It has been to the shop four times in the past 5 weeks. I even switched mechanics after the first one said he was going to replace the 02 sensor and I looked at my records and pointed out that he had already done that back in June. (At that point, they said "Oh"" and tried replacing the TPS sensor.) The 2nd mechanic also got the TPS sensor code and I told him that the previous mechanic had already replaced that one, as well.
He went to a discussion website for mechanics and discovered a "design flaw" that a majority of mechanics said could be rectified by replacing the clockspring. So he tried that. Every time one of these guys does something, the CE light goes off and they test-drive it and it seems fine. Then I come to pick it up, after hours, hours later, when the car has completely cooled off, and the CE light is back on. Yesterday I picked it up and the CE light was on but at least it was running better. Then I drove it 90 miles and it was hiccuping badly by the end of the trip. Also, I filled up my gas tank at the beginning of the trip, and the tank is now between 1/2 and 3/4 full. Horrible mileage. My husband made the same trip in a different car, also a Jeep, and also filled up at the beginning, and his tank is more than 3/4 full.
I know I can take it to Auto Zone and get the code, but I'm not hopeful that the code will say anything other than what it has already said, i.e. O2 or TPS sensor.

I have a 1999 Jeep Wrangler Sport 4.0L with a kind of serious problem. My wipers dont always work. Sometimes they work fine, sometimes they work fine to start with and then quit without warning, other times the only way to get them to turn on is to turn them on high and then go to the speed that I want to use. It has the intermittent option but I am not yet convinced that that has anything to do with my problem. They will quit working some of the time while using the delay but they also quit on low sometimes. I have been through and checked all of the plugs, and even went as far as to grease them up so I know they are making good connections. I'm at a loss, I would think if it were the motor or the switch it would just go out all together. And if it were a broken wire, wouldn't it come on and go off if I hit a bump in the road? They shut off on smooth roads so bumpy or smooth does not matter.

I have a 2006 Sonata. My check engine light came on and also my ESC light. My car does not accelerate. It takes literally about 40 seconds to get up to 20 miles an hour. I called the hyundai 800 number and they said there is a recall for a "stop lamp switch malfunction".

I have a 2006 Jeep Wrangler Unlimited w/ 33k miles on it...4.0 engine. Have had it a little over a year. Last Fall, it started having issues whenever we had a lot of rain. Would not crank at all. Replaced the battery and clutch switch, which seems to worked, but is now doing it again. I turn the key and all of the lights come on, but there is not even a click. If I coast it off and pop the clutch, it starts right up. Once it dries out, will start w/ the key without an issue. Have an appt w/ the dealer, but they cannot get to it until Thursday, but I have to drive to work until then.

I have a 2009 Jeep Liberty Sport 4X4 with 63,000 miles. There have been issues starting the car for about a year and a half.
It all started when a key was inserted into the ignition about a year and a half ago and a click would just be heard after the key was turned to the start position. Usually it started after the key was removed and inserted again. Sometimes it would take a few tries but most of the time it would start right up on the try one.
After 10 months, the battery was replaced after the vehicle had to be jump started. Shortly after, I had a Viper 5901 remote starter installed in the vehicle by a reputable store. The issue seemed to go away and thought the issue was fixed. The vehicle now was started from the remote control 90% of the time.
The issue started to become worse about 2 months ago. It would take more than 15 tries to start and to temporarily relieve the issue; it can be started on the 3rd or 4th try by rocking the vehicle. The starter was replaced two weeks ago by a reputable auto mechanic at my request. I went to a camp the day after for a week and most of the time it just sat in the hot sun except for short errands sporadically throughout the week.
I then went on a week vacation and the car sat in the driveway. I came back and the car didn’t have any power. The battery read 1.2 volts. It was jump started and then I went to work. At the end of the work day, I tried to start the vehicle and just heard the click. After rocking the vehicle, it started right up.
I was curious to why the battery was that low and so I hooked up a meter inline from the battery terminal to the disconnected red wire. Please find the results below:
-Entire top of the fuse box was removed of fuses, relays, etc. – read 0.20A empty – it sounded like the fuse box clicked when the circuit was completed. Not quite sure what was plugged in to draw that much current.
-The fuse box was reconstructed except for a few fuses – read 0.24A
-M13 fuse was connected and current increased to 0.64A (0.40A increase from previous)M13 – 20A fuse for Cabin Compartment Node (CCN)/Wireless Control Module (WCM)/Multifunction Control Switch.
-M12 fuse was connected and current increased to 1.67A (1.03A increase from previous)M12 - 30A fuse for Radio/Amplifier
-Viper fuse was connected and current increased to 1.73A (0.06A increase from previous)
I guess it come down to a few questions:
-What could be the reasoning the vehicle does not start consistently? Is it due to the battery or something else?
-What would draw a ¼ Amp without any visible connections on the top of the fuse box?
-Why would fuse M12 take so much current without a key in the ignition?
-Anything else I should look for?

I have a 2006 Rubicon Wrangler 4.0 (automatic) with 15K miles, excellent cond. When I drive up to the mountains my Jeep loses power to the point I have the gas pedal pushed to the floor, whereas I can jump out of the jeep and run along side of it. When I step on the gas on the freeway going at high speed it dogs down. It runs fine driving around town. I never had this problem before. I don't think its a transmission problem because I have no engine light coming on. I just checked the Catalytic Converter and that's ok. I'm lost, I have no clue what it can be.

I recently purchased a 2004 Jeep wrangler Sahara. In retrospect, I probably should have inspected it more closely. The underside, including the sides of the engine block (below the heads, etc.) have a lot of rust. With little effort I can flake off pieces as thick as a quarter for example. How concerned I should be and what I need to do???

The engine was running rough when it hit 2K RPM only. above and below it is fine. replaced the injectors/O2 sensor and it ran well for a couple of months but it is doing it again. when engine hits 2K rpm it will sputter and run rough. engine light gives me code 171 engine running rich or lean. What else to look at..

I have a 97 Wrangler 4 liter that lurches violently. It runs fine until the engine is warmed up. After the engine warms up it it begins lurching. When I put the clutch in, the lurching stops. When I let the clutch out, it is okay for 1-2 seconds (i can get power and advance the vehicle), then I put the clutch in and repeat that process. When I give it a little gas with the clutch in, the engine runs smooth - so it doesn't appear to be a gas problem. When I give it gas with the clutch out it lurches violently.
After pulling it into my garage I let it idle to about 5 minutes. It idles rough and is about to stall, when it apparently shoots a little more gas preventing it from stalling.The check engine light has come on. I took it to my local mechanic who cannot find the problem. The "computer code" indicates a faulty oxygen sensor. He also checked the fuel pressure which is okay.It has 120K miles and otherwise has been a great vehicle. It has been well maintained.

I own a 2003 Jeep Wrangler and for the past 4 months. I have had a squeal coming from the right side front of the engine when coming off the gas. However when I get below 25mph while slowing to a complete stop the sound goes away in most cases. My mechanic has replace the tension pulley along the the serpentine belt and the sound still persists...

My 2008 chevy aveo has electrical problems, I think, sense I purchased it. First off the clock goes on and off randomly and doesn't keep time. Then the engine light is on one day then off the next. Sometimes on hot days sometimes on cold days. took it to Autozone and they have said two different times said there is a something wrong in the fuel sensor ??? took it to the Chevy dealer 3 time, Once they keep it for 3 days and said they couldn't get the engine light to come on.. ei. nothings wrong. the second time they said it was the sparkplugs and they charged me to replace them. 10 minutes after I got the car back the light came back on. The third time, again they said they can't find anything wrong.So the light as been going on one day and off others..I just ignored it...Yesterday, I was in 5th gear and I lost all power. engine still running but now power when I press on the gas. I managed to pull over, turn off the car and it acted fine. It happened again on the way home from work. Now the light is off and it seems fine.

My 2006 F150 was purchased by me in early 2009 with about 28,000 miles on it. It's an XLT crew cab 4X4 with the 5.4. Stock except for a leveling kit and an aftermarket head unit. It currently has about 59,000 miles and has been babied since I purchased it. About 3 years ago I started noting some issues:
A. Oil pressure dummy gauge is all over the place. Some times it will show no oil pressure. Other times it is all the way to the highest mark. Other times the needle has gone 180 degrees past where normal is and is actualy pointing straight down towards the floor.
B. Recently my alternator dummy gauge has started doing the same thing as my oil pressure gauge.
C. The backlight behind my odometer works intermittently, but mostly not at all.
D. My dome light will flicker when first turned on. It doesn't matter which door is opened or if the override switch it turned on. It takes several seconds to come on and will flicker like there is a poor connection somewhere, but stays on once its on.
E. Blower fan will occasionally stop blowing. Once the climate control switch is turned to off, then back to on it resumes working. This doesn't happen often, but does occasionally.
Fortunately, the truck has not left me stranded and I want to keep it that way. We are getting ready to sale my wife's Toyota and this will become her daily driver. I want to take care of any issues before she starts driving it. Are these all separate issues or is there one common issue which could be causing them all?

2003 Jeep Wrangler LOUD squeal when coming off the accelerator. I've had changed the Tension Pulley, The Belt, Checked the Power Steering, Removed the belt from the AC unit..smaller belt now....Tested the Alternator, it's working like a champ. I have a 4.0L 6 Cylinder. My mechanic wants to check the intake gasket and another intake which he spoke of and I can't remember at the moment however with no guarantees these or one of the two could be the problem. He expects it to be a 5 hour job. The sound seems to be generated from the lower backside of the engine...

This morning, I tried to start the 2003 Prius and got a 'check engine' light and nothing. The cabin lights were bright so the 12V looked OK. After three tries, I used the VOM and measured 12.55 V on the battery. But the traction battery level looked unusually low.
So I tried again and it started. Using the ScanGauge, no codes were displayed. So I turned the car off and on three times and cleared the "check engine" light. Then I connected the Auto Ingenuity and read out:
P1636 - HV ECU Malfunction on the HV ECU to ECM bus.
C1213 - HV ECU Communication Circuit Malfunction between HV ECU and Brake ECU
P3002 - HV ECU Communication Malfunction on the HV ECU to Battery ECU
So it looks like there was an HV ECU problem that 'cleared while testing.' Certainly it makes sense to inspect the HV ECU connectors and re-seat them and clean out any debris.

I own a 2001 Jeep Cherokee with 104,000+ miles. It runs great and doesn't have any issues. However, i started it up this morning and the check engine light came on. Should this be concerning? I haven't done any real maintenance on it since it runs so well. And i guess that's my other question - what should i do to the Jeep to keep it running for another 100,000+ miles? Spark plugs? Timing belt??
