Diagnostic Aids
- A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor parameter on the scan tool to increase rapidly. This increase should be from 4-10 g/s at idle to 210 g/s or more at the time of the 1-2 shift.
- A high resistance of 15 ohms or more on the 12-volt reference voltage circuit will cause this DTC to set. A high resistance will cause a driveability concern before this DTC sets.
- If the condition is intermittent, refer to Inducing Intermittent Fault Conditions and Intermittent Conditions .
