Hi there:
This code is set when the MAF (Mass Air Flow) meter is not sending the PCM the correct information. This can be due to a bad conection of the rubber intake hose between the MAF and the Throttle plate opening, a dirty air filter, a dirty mass air flow or a bad mass air flow.



Most programmer have you tie into the iat sensor in the mass air flow. this can cause the the iat sensor oto short out.


Hope helps.
