Diagnostic Aids
- Inspect the air induction system for any water intrusion. The water rapidly cools the hot sensing elements in the sensor causing a false indication of excessive air flow. Any water that reaches the MAF sensor will skew the sensor and may cause this DTC to set.
- A poor connection at the fuse for the ignition 1 voltage circuit of the MAF sensor may cause this DTC to set.
- If the condition is intermittent, refer to Inducing Intermittent Fault Conditions and Intermittent Conditions .
