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 steady or intermittent high resistance in the 12-volt reference circuit of the MAF sensor will skew the MAF sensor frequency high and may cause this DTC to set.
- If the condition is intermittent, refer to Inducing Intermittent Fault Conditions in Wiring Systems and Intermittent Conditions .
