Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- Inspect for the following conditions:
- A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
- Any contamination of the hot film element of the MAF sensor may cause this DTC to set.
- A skewed or stuck throttle position (TP) sensor 1 or TP sensor 2 may cause this DTC to set.
- A wide-open throttle acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 3-7 g/s at idle to 72 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
- If the condition is intermittent, refer to Intermittent Conditions .
