Symptom:
P0108-MAP SENSOR VOLTAGE TOO HIGH
When Monitored and Set Condition:
P0108-MAP SENSOR VOLTAGE TOO HIGH
When Monitored: Engine speed between 600 to 3500 RPM. TP sensor voltage less than
1.2 volts. Battery voltage greater than 10 volts
Set Condition: The MAP sensor signal voltage is greater than 4.96 voltsfor 1.7 seconds.
MAP SENSOR VOLTAGE ABOVE 4.6 VOLTS
(K1) MAP SENSOR SIGNAL CIRCUIT SHORTED TO (K6) 5-VOLT SUPPLY CIRCUIT
(K1) MAP SENSOR SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
MAP SENSOR INTERNAL FAILURE
(K1) MAP SENSOR SIGNAL CIRCUIT OPEN
(K4) SENSOR GROUND CIRCUIT OPEN
PCM
TEST
1 Start the engine.
With the DRBIII , read the MAP Sensor voltage.
Is the voltage above 4.6 volts?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION symptom in the
No
2 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K1) MAP Sensor Signal circuit and the (K6)
5-volt Supply circuit in the MAP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to (K6) 5-volt Supply circuit in the (K1) MAP
→ Go To 3
No
