- PCM monitors input voltage from MAF sensor when engine is running. If input voltage is below 0.21 V
, PCM determines that MAF circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if PCM detects the above malfunction condition during first drive cycle.
- PENDING CODE is available if PCM detects the above malfunction condition.
- FREEZE FRAME DATA is available.
- DTC is stored in the PCM memory.

| POSSIBLE CAUSE |
- MAF sensor malfunction
- Connector or terminal malfunction
- Short to ground in wiring harness between MAF/IAT sensor terminal C and PCM terminal 1AK
- Open circuit in wiring harness between MAF/IAT sensor terminal C and PCM terminal 1AK
