Tests 6 - 9:

SYMPTOM
P0108 - MAP SENSOR VOLTAGE TOO HIGH

WHEN MONITORED
With engine speed above 400 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 ground circuit open
- MAP sensor wiring harness intermittent defect
- MAP sensor wiring harness observable defect
- MAP sensor signal circuit open
- MAP sensor
- Powertrain Control Module
- MAP sensor signal circuit shorted to volt/O2 sensor signal circuit
- Sensor signal circuit shorted to 5 volt supply circuit
