Symptom: P0107-MAP SENSOR CIRCUIT LOW When Monitored and Set Condition: P0107-MAP SENSOR CIRCUIT LOW When Monitored: Engine speed greater than 250 RPM. Battery voltage greater than 10.3 volts. Set Condition: The MAP sensor signal voltage is below 0.08 of a volt for 1.7 seconds. One Trip Fault. POSSIBLE CAUSES MAP SENSOR VOLTAGE BELOW 0.08 OF A VOLT (F856) 5-VOLT SUPPLY CIRCUIT OPEN (F856) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND MAP SENSOR (K1) MAP SIGNAL CIRCUIT SHORTED TO GROUND (K1) MAP SIGNAL CIRCUIT SHORTED TO THE (K900) SENSOR GROUND CIRCUIT PCM TEST ACTION APPLICABILITY 1 Ignition on, engine not running. t, read DTCs and record the related Freeze Frame data. With the DRBIII t, read the MAP Sensor voltage. Is the voltage below 0.08 of a volt? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION Symptom (Diagnos- tic Procedure). 2 Turn the ignition off. All Yes → Go To 3 No → Go To 6 3 With the DRBIII t, monitor the MAP Sensor voltage with the Sensor harness connector disconnected. All Yes → Replace the MAP Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 4 57 DRIVEABILITY - NGC |
