Help with Code 10 (IAT) with an H22/Accord swap
Hey everyone,
New to this board (not new to the scene), and I'm hoping that someone here can help me out with my problem.
I swapped an H22 into my 95 Accord about 18 months ago. For the most part, everything has been fine, and I couldn't be happier with the swap. However, there's been one thing that's been popping up.
For quite some time now, my ECU likes to throw code 10 (Intake Air Temp sensor) after the car is warm and when the weather is warmer out (usually above 60 degrees). Let me run down the items and symptoms:
- As I said, it will only happen when the car has been running for awhile and when it's hot outside. EXCEPTION: On extremely hot days (like today), it'll throw the code as soon as I start the car.
- When it comes on while driving, I can feel the ECU retard the timing and cut my power.
- I'm not running hot, and all things in my car are carefully maintained (full oil, full coolant, well-running plugs, distro, timing, etc).
- I've replaced the IAT sensor with a new one, and that's not the problem.
- When I swapped my H22, I had a problem making the fans work, so I jumpered the fan switch to make the fans be on all the time (yeah, ghetto, I know).
OK, so my thoughts are these. I could try getting a cold air intake (currently running a filter on a stick), but I don't think that's the problem, since, as I said, the code will come on as soon as I start the car on REALLY hot days. The reason for that, I think, is the black hood I have is heating up the air under the hood, and causing SOME sensor to get extremely hot.
My question is: Could having the fans jumpered have something to do with the code? In other words, would the ECU be freaking out about a sensor getting hot WITH the fans being on, and throwing the code? I don't think this is the case though, since the ECT switches don't appear to run to the ECU according to my Helm's manual.
I've done almost all the troubleshooting in my Helm's manual, without any luck.
I've got a few more items to check before I send the car to the wrecker. One of these involves getting a pinout for a JDM P13, since I think the JDM and USDM ECU's are different. My reason for this is, my Helm's shows there being TWO Engine Coolant Temperature switches, and my engine came with one. Can anyone help me out with that as well?
I know this is alot of stuff. Any help would be appreciated.
