Hi guys. New to this forum, hoping someone might be able to help.
I have a 2009 Honda Accord Mk8 2.2 i-Dtec manual. I recently had a DPF issue where the filter was clogged. I've had it cleaned and regenerated and that is all sorted now. However, a couple of days later I went to start the car in the morning and the check engine light came up. I plugged in my OBD2 scanner and found the following 2 codes:
P0181 - Fuel Temperature Sensor Circuit Range/Performance
P2199 - Intake Air Temperature Sensor 1/2 Correlation.
I have been driving the car since April this year and not had any issues until very recently when I had the DPF issue and now this has come up one a day or two later. Could the DPF regen have triggered this fault in some way? Or I am wondering if the two codes have anything to do with the cold weather, as in whatever sensor is giving the fault, it isnt working correctly due to the temperature being very low? Obviously, it means that the part/sensor is probably faulty, but the fault is just becoming apparent due to the cold temperature?
Anyways, thinking that the cold may have something to do with one of the sensors not reading correctly or maybe being a one-off issue, I removed the codes and I drove the car around to warm it up a little. The codes did not come back the whole day and the car was running fine. Next morning I start the car up and the same two codes show up again. This time I removed the MAF sensor and cleaned it with MAF cleaner thinking that the Intake Air Temperature sensor in the MAF may be dirty. Then removed the codes and the car was fine all day again until the next morning when the same two codes show up again.
I have been searching online for the location of the Fuel Temperature Sensor on this car, but I can't seem to find it anywhere. I have the Haynes manual for the car, but it is pretty useless, with about 80% of the info being generic and not always useful for this car. Another thought is the MAP sensor. Could that have something to do with it?
Any thoughts from any of you guys would be much appreciated.
