Symptom: P0107-MAP SENSOR LOW When Monitored and Set Condition: 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 .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 TEST ACTION APPLICABILITY 1 Start the engine. t, read the MAP Sensor voltage. Is the voltage below .078 of a volt? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION symptom in the Driveability category. 2 Turn the ignition off. All Yes → Go To 3 No → Go To 7 53 DRIVEABILITY - NGC |
