Symptom: P0108-MAP SENSOR VOLTAGE TOO HIGH When Monitored and Set Condition: P0108-MAP SENSOR VOLTAGE TOO HIGH When Monitored: With the engine RPM above 400, the TPS voltage less than 1.13 volts, and battery voltage greater than 10.4 volts Set Condition: The MAP Sensor signal voltage is greater than 4.88 volts at start or with the engine running for 2.2 seconds. POSSIBLE CAUSES MAP SENSOR VOLTAGE ABOVE 4.8 VOLTS MAP SENSOR (K1) MAP SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE (K1) MAP SENSOR SIGNAL CIRCUIT OPEN (K1) MAP SENSOR SIGNAL CIRCUIT SHORTED TO (K7) 5-VOLT SUPPLY CIRCUIT (K900) SENSOR GROUND CIRCUIT OPEN PCM TEST ACTION APPLICABILITY 1 Ignition on, engine not running. t, read DTCs and record the related Freeze Frame data. Start the engine. t, read the MAP Sensor voltage. Is the voltage above 4.8 volts? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION Symptom (Diagnos- tic Procedure). 2 Turn the ignition off. t, monitor the MAP Sensor voltage. Is the voltage below 1.0 volt? All Yes → Replace the MAP Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 3 NOTE: Remove the jumper wire before continuing. 31 DRIVEABILITY - GAS |
