SYMPTOM
P0107-MAP SENSOR LOW

WHEN MONITORED
Engine speed between 600 to 3500 RPM. TPS voltage less than 1.2 volts. Battery voltage greater than 10 volts.

SET CONDITION
The MAP sensor signal voltage is less than 0.0782 of a volt for 1.7 seconds. One trip Fault.

POSSIBLE CAUSES
- MAP sensor voltage below 0.078 volts
- (K6) 5 volt supply circuit shorted to ground
- (K6) 5 volt supply circuit open
- MAP sensor internal failure
- (K1) MAP signal circuit shorted to ground
- (K1) MAP signal circuit shorted to (K4) sensor ground circuit
- PCM (K6) 5 volt supply circuit
- PCM (K1) MAP sensor signal circuit
