SYMPTOM
P0108 - MAP SENSOR VOLTAGE TOO HIGH

WHEN MONITORED
With the engine speed above 400 rpm, the TP sensor voltage less than 1.13 volt, and battery voltage greater than 10.4 volts

SET CONDITION
The MAP sensor signal voltage is greater than 4.88 volts at start or with the engine running for 2.2 seconds.

POSSIBLE CAUSES
- MAP sensor ground circuit open
- MAP sensor wiring harness intermittent
- MAP sensor wiring harness observable problem
- 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
- PCM (MAP sensor voltage too high)
