SYMPTOM
P0107 - MAP SENSOR VOLTAGE TOO LOW

WHEN MONITORED
With engine speed above 400 rpm but less than 1500 rpm and the TP sensor voltage less than 0.5 volt.

SET CONDITION
The MAP sensor signal voltage is below 1.2 volts at start, or below 0.02 volt for 1.76 seconds with engine running.

POSSIBLE CAUSES
- MAP sensor 5 volt supply circuit open
- MAP sensor voltage above 4.0 volts
- MAP sensor circuit shorted to ground
- MAP sensor signal shorted to ground circuit
- MAP sensor wiring harness intermittent defect
- MAP sensor wiring harness observable defect
- PCM defective (no 5 volt to MAP sensor)
