SYMPTOM
P0108 - MAP SENSOR VOLTAGE TOO HIGH

WHEN MONITORED
With engine speed above 400 rpm but less than 1500 rpm and the TP sensor voltage less than 1.0 volt.

SET CONDITION
The MAP sensor signal voltage is greater than 4.6 volts at start or with the engine running for 1.76 seconds.

POSSIBLE CAUSES
- MAP sensor defective
- MAP sensor ground circuit open
- MAP sensor signal circuit open
- MAP sensor signal circuit shorted to voltage
- MAP sensor wiring harness intermittent defect
- MAP sensor wiring harness observable defect
- PCM defective (MAP sensor voltage too high)
