Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.

Inspect for the following conditions that may set this DTC:

Any condition that can cause the MAF, MAP, SCIP, and TP sensors to be shifted in value.
Any condition that may cause the supercharger by-pass valve to bind or stick in either the open or closed positions.
A slight to moderate resistance of 10-20 ohms on the MAF sensor ignition or ground circuits may cause this DTC to set.

CAUTION: Refer to Road Test Caution .

Road test the vehicle and verify that the MAF sensor calculated g/s and the actual MAF g/s parameters are near or equal to each other.
A skewed MAF sensor, intake air flow restriction or intake air flow leak after the MAF sensor may cause the calculated g/s and MAF g/s parameters to disagree. Road test the vehicle while observing both parameters under various engine loads.
A skewed or stuck ECT MAF/IAT, or IAT sensor 2 will cause the calculated models to be inaccurate and may cause this DTC to run when it should not. Refer to Temperature Versus Resistance .
