Ford F-150 - 1997-2003 :: IAC Over Speed Error Code P1506
About 3 days ago I noticed my engine RPM was around 250 higher than usual. Usually my truck idles around 550-600 rpm (I know this is low). Anyway, yesterday it threw the P1506 "IAC over Speed Error" Code. It is idling very rough, shifting weird, but does crank up fine.
My truck is now at 93,000 miles and I just cleaned the IAC at 87,000 miles due to the common no start condition. I guess I am going to get a new IAC now since another code came up.
Well, my question is it came up with two other codes also:
P0171 - System too Lean, Bank No. 1
P0174 - System too Lean, Bank No. 2
Do you think the P1506 (IAC Code) made the O2 Sensor codes show up or is it really the O2 Sensors? I just changed my two upstream O2 Sensors around 90,000 miles. Should I get a new IAC or try to clean it again?
Ford F-150 - 1997-2003 :: 2002 - Got Error Code PO174
Looking for some experience/recommendations for the "what to do" and "in what order" for an error code. Recently the "SERVICE ENGINE SOON" light came on and has stayed on for the last 2 weeks. It has don this before after a heavy rain but went off after a few days but not this time. I took it to Advance Auto who hooked it up to a Trouble Code Reader and got back "PO174- Bank 2 system to lean". From what I've read from the Haynes book and other forum postings this is either a O2 sensor issue or a intake manifold gasket issue? Does this sound right? Next is how to go about addressing this issue in a systematic manner so as not "fix" 10 things that don't need fixing and not running to mechanic and paying a buttload for something I can do myself for less.

What that means? The check engine light is NOT on but I looked for a code because my truck is idling rough, and when driving, when the overdrive kicks in, it vibrates really bad. As if a bad U-joint on your drive shaft. The truck has been in a field for about 5 months broke down so any clue? Haynes manual says nothing about P1000.

1999 F150 4.2L 125K miles.... My problems started about a month ago. I had a P1506 error. The engine was running fine but received the error code. I replaced the IAC and the air filter. Engine still running fine. A week later I received a code for the Intake Air Temp Sensor (don't remember the code). The engine still running great. I bought a new Air Temp Sensor and noticed the wires from the Air Temp Sensor were rubbing against the belt and had been severed. I made a mistake when replacing the air filter of not checking the wires (confession is good right).
The engine also constantly ran a fast idle 2000 to 2500 at this time. I repaired the wires. The engine light went off and idle now starts great and smooth but when heats up will will go to 2000-2500. I then decided to replace the Air Temp Sensor hoping to fix idle problem. Engine still idle fast when warm. However, when I come to a stop and put in neutral the engine will take a minute but go down to normal idle after sitting. Engine light stayed off for a week. Now engine light back on with original code P1506. Idle is still not working correctly.
I feel like I made it worse than it was originally and not sure what to try next.
Ford F-150 - 1997-2003 :: Vacuum Leak On PCV Hosing - P1131 Error Code
I'm getting the p1131 error on my 2000 xlt f150 5.4l. I know it's usually a vacuum leak on the pcv hosing, which I did have at the back and replaced as well as other softer joining sections(3 to be exact lol), but I'm still getting this error. Changed out my plugs and cops(as they needed it) and the back two plugs on both bank 1 and 2(plugs 4&8) were both white! Since this is an obvious indication of a lean burning cylinder can I make the assumption my most likely problem is dirty fuel injectors on those cylinders?

I was driving along today and my Check Engine light came on. I stopped at the nearest Advance Auto to have them pull the code and it came up with the P0420, Catalyst Efficiency Below Threshold (Bank 1). I asked what could cause this and they mentioned that the fuel that was put in could be causing it. They didn't mention any other possible causes. Any others? I'm thinking it could be the fuel because the last gas station that I stopped at and filled up at is one that I never go to, and maybe just got a bad batch of fuel.

I'm getting an error code 2-7 (flashes two times, pauses, then flashes seven times) when my truck starts up. It does this cycle twice then stays on permanently. It has only started doing this since last night when I replaced my factory tape deck with a factory Cd player from a 2002 F-150.

I have received the error code P1506 on my 1999 F150 which is I believe an idle air control overspeed error. It seems to run a little rough at idle but not too bad. At the advice of my Haynes repair manual and the advice of a friend I have already replaced the IAC valve and the PCV valve on the engine and cleared the code, only for it to come back again after 50K miles. I am not sure where to go next with the diagnosis/fix.

I had been having battery issues with my 97 ford f150 4.6 liter for the longest time, thought i had a short under dash, i pulled entire dash out, disconnecting bat first of course, and inspected all wiring harness connections and fixing my issues and putting it all back together. now with new bat and all put back together i am now getting the airbag light flashing 5 times then 2 times (error code 52) i know it has some thing to do with power failure or backup battery, but now with the new battery in i cant seem to get it to reset. How to do this?
View 3 RepliesLexus SC430 :: Oxygen Heater Circuit Malfunction - Code P0155
SC430 came up with the check engine light, showing a "Oxygen Heater Circuit Malfunction", code P0155 (bank 2, sensor 1). Searching, I found out this is the oxygen sensor in the passenger side exhaust manifold.
My car is high mileage (over 130K), it's hard to justify purchasing a $230 sensor and paying for installation. My only goal is to keep the check engine light from turning on and passing state inspection/emission (the check engine light will prevent passing inspection/emission in my state).

View 5 RepliesFord/Mustang :: 1997 - Getting Error Code P0304 / Cylinder 4 Misfire
1997 Ford Mustang 4.6L EFI engine with 67K miles. The engine is actually now in a Factory Five Roadster. It sat on a stand for 5 years but runs well now with the exception of the code. I keep getting a code P0304 (cylinder 4 misfire) and I've checked the plug - the code seems accurate; it is misfiring.
Things I've tried:
1)swapped plugs,
2)this is a dual coil engine so I've swapped coils,
3)the #4 plug is the longest sparkplug wire so I've gotten high-performance wires,
4)heavily grounded the AL head,
5)put dielectric grease on the plug,
Still, ONLY cylinder 4 gives the misfire.
Avalon 2005-12 :: CEL Error Code P0440 Error Code / Charcoal Canister Replacement
So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.
Escort :: 1997 - Getting Error Code P1131?
My car has lost power. The engine seems bogged down and it has a significant sputter when accelerating and acts like it wants to die when idle. I am getting error code P1131. AutoZone did not give me any info on the code. I have changed the plugs and wires. I have been told this might be o2 sensors but after reading other stuff here, it looks like maybe a vacuum leak? I am not sure where to start at diagnosing this issue.
View 14 RepliesCivic - Honda :: 1997 - CEL Came On With Error Code PO135?
I have a 97 Honda Civic Manual transmission and my Check Engine Light Came On. The error code is P0135 which shows up as needing a O2 sensor. My question is:
1. Do I need to replace it?
2. How long do I have to replace it?
3. Will driving with it as it hurt my car?
The weather is getting colder and I read that could be the cause. I really don't have much extra money but I don't want to kill the car. I have kept up on Oil Changes with MaxLife Full Synthetic, Radiator Flush, etc if that matters. I also went into Valoviline Instant Oil Change and they double checked all of the fluid levels and that was OK.
Ford F-150 - 1997-2003 :: Misfire Error Codes - CEL On?
Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors???
I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?
