About 2 months ago, the check engine light came on and I had the code read, it came out as P0031, which is the 02 Sensor. Today, I had this 02 Sensor replaced and had the code reset, but later on today the check engine light came on again. The mechanic said I needed to drive it for about 100+ miles before the car resets itself. I drove it for about 30 miles before it did come back on.
View 8 RepliesCheck engine like on my 03 Camry with 2.4L is own & got an OBD code of P0031. Just bought the car with 38k miles one owner & can't pass local emissions.
View 10 RepliesWhat to do to get rid of P0031 check engine code on my 4 cyl. Camry LE. He replaced O2 and A/F sensor (Denso with CA emission), computer module (got dealer calibrated it), verified wiring/voltages, inspected the catalytic converter. When the code is cleared it will not come up for some time, but when the car is started cold it comes right back again.
View 2 RepliesI own a 2003 Camry LE. I went to Autozone to find out what the check enginge light was for and was given P0031. When the service person checked it out on the computer he said the probable causes were:
1) open or short circuit conditions
2) poor electrical connections
3) failed oxygen sensor
4) EFI relay fault.
I asked how it could be narrowed down and he said it I would have to get the car checked out.
VSC, Check engine light just came on my 2006 GS300. I only have 50k miles on it. I had this happen a few years back and it was the Gas cap o-ring. This time I changed the gas cap and reset the codes but no luck. After starting the car, with a minute the lights come back on. So checked the code and here is what I'm getting:
P0031
Heated Oxygen
Sensor Heater
Control Circuit Low
Bank 1 Sensor 1
Doing a search for the code yields this: [URL] .....
Changing the sensor vs. checking something else that might be the issue?
I have a check engine light come on in my 07 Avalon and had the car scanned. It was throwing error code P0031. I'm gonna go ahead and replace this O2 sensor, however, I'm having a hard time finding the correct part# for this sensor.
View 1 RepliesI received error code P0031 on my 06 Avalon the other day. It states that the HO2S (Heated Oxygen Sensor) is bad. Bank 1 Sensor 1. I located the sensor but have a few questions...
Just to give an over view for those that don't know where these are, there are 4 sensors the one in the front on the manifold (upper - B2, S1), (lower - B2, S2) and the rear manifold (upper - B1, S1), (lower - B1, S2).
All of the sensors look the same with 4 wires. what the part number is for the sensor? Also since this is the hardest one to get to, I would like to know where the wire routes to. I found the wire up to the connector on every other sensor except the one I need (B1S1). It looks like it runs towards the top of the engine but from the top I don't see it.
CEL came on today and when I ran the codes I got P0741. Torque converter CKT Performance or Stuck Off. What the next steps are.
View 1 RepliesWhat this code may mean and what type of expense will I be looking at? Is it something I could fix or does a dealer need to perform this repair?
View 4 RepliesWell, finally! After wanting a code to troubleshoot this low gas mileage and fuel smell (outside the car, usually, but sometimes inside the car also) for 3 months, I FINALLY got a trouble code.
Bad news is: it's P0457.
2001 2.7L. Where would you check first? I've already replaced the cap and pump (the old cap was fine). Pulled the EVAP can off today, no holes or anything that I saw to cause a leak. Where is this "two-way valve" located? Think it might be the place to look?
I have a 2005 Santa Fe with the 2.7l engine....during the last two summers I've had this code pop up only to disappear. Well, we're into the winter here in New York and the code popped up again and after a week its still on. What's causing this and are there any easy fixes? The wife loves the SUV, its got 120,000 miles on her, the engine is strong and the tranny was rebuilt this summer (that another story).
View 1 RepliesSo I go on vacation, and as we're driving down, the CEL comes on with p1166 pd1166. Get home the code still pops up. A month later small oil leak is detected. Clean the throttle body intake, fuel and exhaust systems. Oil leak gets worse, turns out the crank shaft seal has failed. Shop cleans out the oil, and replaces the timing belt. Clears the code and the CEL stays off for 5 days. I clear the code and Its good for days. Get it up over 50 and the CEL pops on. So today go for a trip mostly highway driving. I go over 125 miles with out the CEL coming on. Check it and the reader reports pd1166. Clear it. Driving back 4 miles and the CEL comes on. 2 codes p1166 and pd1166.
What are the time parameters for logging a pd1166 and the p1166. No engine issues, no performance issues. Gas mileage is 17-19mpg.
I've checked the lines from the Purge Valve on the Passenger side of the Intake Manifold, Check OK
I've Checked that Valve OK
I've Replaced the Canister Close Valve
I've got the Gas Cap tight.
I've removed the rubber bushing holding the CCV to the Evap Canister, hoping to isolate the Filter and point the blame on it, no luck there!!
I'm thinking next is to drop the Tank and check over all the Goodies on top.... as much as I hate the thought of that, the two access holes under the seats, just don't allow access to enough of the tank!
any thing there that I could suspect, I see there's a check valve!
There's also the Fuel Tank Pressure Sensor, which may be at fault.
I just purchased a 2005 Santa Fe, 4WD, 2.7l..the engine has a miss...the code that came up was "misfire in #2 cylinder"..I checked the coil pack...and the wire harness just crumbled..so I replaced the coil pack...reset the code..and it was good for a couple of days...I got through inspection...today I put on the A/C..and the engine got rough..the check engine light came back on..same code..misfire in #2..I'm thinking the injector or what else could it be? plug? wire?
View 3 Replies05 santa fe/3.5L/ owned since new. Had a misfire problem and solved that by changing coils/plugs/wires...
Still getting a P0430 code (bank 2 cat efficiency low)
Following the Repair manual troubleshooting of that code says
Read H02S - got a scan tool and did that -
Comparing Bank 1 H02S1 and 2 show they are are different voltages and do not follow.
Comparing Bank 2 H02S1 and 2 show nearly identical traces.
I also checked the wiring harness around the sensors and check for air leaks...couldn't hear/see/feel any.
My conclusion based on the info obtained is that the bank 2 cat is bad and needs to be replaced.
My 2003 Santa Fe 3.5 is in limp mode, you can't change the gears and showing signs of faulty tps sensor, but my mechanic is telling me to change whole electronic throttle system , May be its only the sensor.
View 1 Replies2002 Santa Fe 2.4L Automatic. Driving on the freeway when it lost power. Couldn't go over 65 even with the accelerator all the way down, even slower on uphill climbs. The engine wouldn't rev higher than around 3000rpms.
I figured it sounded like a loss of power due to weak fuel pump. I replaced it as well as the fuel filter, and verified it was pumping. Put the car together, and still the same loss of power. Drove home and parked it, but next morning it won't run at all. It cranks all day long but doesn't fire.
So far, I have made the following repairs and checks:
-Verified catalytic converter was clear and not plugged
-Verified fuel pressure
-Checked spark plugs - all are good and gaped properly
-Replaced crank position sensor (With the code, I thought this would solve it)
-Verified timing belt and cam belt in time - both have also been changed recently
-Checked all relays and fuses
-Battery and alternator are good - both are new
I still have a crank no start issue, and I'm going crazy taking things apart and putting them back together only to have this car not fire.
It seems that i'm most likely going to have to replace the entire plenum .
P1159 here are some details. [URL]..................
I've checked all connecting wires and none appear to be loose. When the issue started to occur and prior to discovering the P1159 code, I also replaced all coils. I replaced the coils because one was arching over to the metal of the engine. I assumed this may be my problem. The issue still persisted obviously. The check engine light never came on so I assumed I wouldn't get a code. I took it over to a friends house with a code reader and that's when I discovered that it was actually giving the P1159 code.
Are there any other model cars that utilize the same engine that I could use the plenum from? Getting this in working condition is going to be the difference in what I can get for it.
My brother's 2005 Santa Fe keeps locking up in 3rd gear. I've read around here that the P0715 error code that I have is for an input sensor, but I replaced that and it still doesn't work. I also tried the vehicle speed sensor as well and it didn't work.
I was with someone at AutoZone who pulled up a page here that said no I really needed to replace the transmission control module but I can't find that thread here.
I have a 2004 Santa Fe with the 3.5. Today I started it and the check engine light came on. It was not on before this. (We had a lot of wind and rain from the storm but nothing major.) And seems to be running fine. I went to the auto parts store and they ran a diagnostic and the Code P0306 came up #6 cylinder misfire. They said probably Spark plug, wire or coil for #6, then went to look up code in computer and did not have my truck so they went with Kia or Domestic, which gave different possibilities for a code P0306.
They had me buy some fuel injector cleaner as injector was on the list. The light is still on so I guess the cleaner was not the magic bullet. I spoke to a lady at another auto parts store who is a wiz when it comes to cars and has been around them and fixing them a really long time. She says the Code P0306 is Spark Plug, wire, coil #6. She has a 4cyl Hyundai car not truck and she had the code for her #4 misfire in the past and she started her repair cheapest first, Plugs, wires her code was still there she then changed the coil and that did the trick for her.
I on the other hand can't do this stuff myself. Can't afford the dealer anymore or to have a shop do a tune up AND coil if I don't need all new plugs and wires just a coil as they will charge a lot to do a lot all. And it may not need it or even be any of those things. I also suspect the dealer and shops will want to still hook up their computers to do an costly diagnostic because the light is on, even though I know the parts store already came up with a code P0306 twice. Spoke to the dealer on the phone and he already basically said they would want to do that first for $100 plus the cost of repair.
I brought the truck new. It now has 91,500 miles on it and the dealer has already done two tuneups on it in that time, Plugs and wires. I hear it probably shouldn't have even needed these tuneups in this amount of millage? So the last one was probably about 2 years ago and a few thousand miles maybe a guess 10,000-20,000 miles ago. Do you think a plug and wire would be bad already in that few miles?
I got a check engine light. I went to Auto zone to get it read & they came up with a P0303 - Cylinder 3 misfire. Since I bought the vehicle a couple of months ago, I don't know when the plugs were last changed, so I decided to change them. However . . .
Is there a secret to getting the plug boots & wires out of the hole and off the plug without wrecking the wires?
