Hello, I am Randall. Chances are the PCM is ok as to date? never seen one fail for just IAT circuit. the problem is the IAT is built into the mass airflow sensor. W ithout scan tool hooked up viewing data from the sensor? I have to lean to bad IAT and thus requires changing the MAF sensor as one unit
It was fine earlier today I just added a new K&N air intake per instructions included with the kit and this went off, very weird
hello i need more help
Are you there I need aid
You did not say you did mods to the intake. All you can do is check the plug at MAF or the MAF sensor will not take the K/N
ok i guess I can try that again seems it should work, does the computer on the car need time to adjust to the new intake?
yes.. it can take what we call drive cycles. this could be a day, and hour or even more depending how long for ECM to relearn
ok cool sounds right I will just give it some time to adjust I had it on before and I do recall the same issue occuring just recently put stock airbox on for long drive and reinstalled K&N intake today, so this should right itself with time, does that sound right to you?
should i try using a cleaner to clean the sensor
you can try but.. if no problems prior to KN, then the system may not like it
yes, long drives at various conditons allows computer to relearn
ok i will leave as it is and worse case i will get a new sothank you for your help i will just be patient, have yourself a good day
Do the same. It may very well correct itself real soon
i hope so
