SYMPTOM
P-0107 MAP SENSOR VOLTAGE TOO LOW

WHEN MONITORED
With engine rpm above 416 but less than 3520 and 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 below 0.1 volt for 2.0 seconds with engine running.

POSSIBLE CAUSES
- MAP sensor defective
- 5-Volt supply circuit open
- 5-Volt supply circuit short to ground
- MAP sensor harness/connectors observable defect
- MAP sensor signal circuit shorted to ground
- MAP sensor signal circuit shorted to ground circuit
- MAP sensor wiring harness/connectors intermittent defect
- PCM defective (5-volt supply circuit ok)
- PCM defective (5-volt supply circuit voltage low)
