SYMPTOM
P0108 MAP SENSOR VOLTAGE TOO HIGH

WHEN MONITORED
With engine rpm above 400 RPM but less than 3520 RPM and the TPS 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
- MAP sensor ground circuit open
- MAP sensor wiring harness intermittent defect
- MAP sensor wiring harness observable defect
- MAP sensor signal circuit open
- Power control module
- MAP sensor signal circuit shorted to battery voltage
- Sensor signal circuit shorted to 5-volt supply circuit
