SYMPTOM
P0108 - MAP SENSOR VOLTS TOO HIGH

WHEN MONITORED
With the engine speed above 600 rpm but less than 3500 rpm, the TP sensor voltage less than 1 volt.

SET CONDITION
The MAP sensor signal voltage is greater than 4.9 volts at start or with the engine running for 2.0 seconds.

POSSIBLE CAUSES
- MAP sensor ground circuit open
- MAP sensor wiring harness intermittent defect
- MAP sensor wiring harness observable defect
- MAP sensor signal circuit shorted to battery voltage
- MAP sensor signal circuit open
- MAP sensor signal circuit shorted to 5 volt supply circuit
- MAP sensor defective
- PCM defective (MAP sensor voltage too high)
