SYMPTOM
P-0108 MAP SENSOR VOLTAGE TOO HIGH

WHEN MONITORED
With the engine RPM above 400 but less than 1500 and 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
- NO possible causes remaining
- MAP sensor defective
- MAP sensor ground circuit open
