SYMPTOM
P0107-MAP SENSOR VOLTAGE TOO 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 below 0.0392 volt for 1.7 seconds.

POSSIBLE CAUSES
- MAP sensor voltage below 0.04 volts
- (K6) 5-volt supply circuit shorted to ground
- (K6) 5-volt supply circuit open
- MAP sensor internal failure
- (K1) map sensor signal circuit shorted to ground
- (K1) map sensor signal circuit shorted to the (K4) sensor ground circuit
- PCM
