DTC Parameters

WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

At lower throttle angles, the thresholds for deviation will be tighter.
TP sensor No. 1 and TP sensor No. 2 signal deviation is less than 0.6 percent (TP sensor signals correlate with each other).
Vehicle is not at wide open throttle.
Long Term Fuel Trim (LTFT) is -8.1-8.1 percent at idle and -23-23 percent at cruise and accel.

DTC sets when MAF sensor airflow value is too far out of agreement from ECM calculated airflow value (based on engine speed and TP angle).
