P0108-MAP SENSOR VOLTAGE TOO HIGH —
TEST
3 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Turn the ignition on.
Measure the voltage of the (K1) MAP Sensor Signal circuit in the MAP Sensor
harness connector.
Is the voltage above 5.2 volts?
Yes → Repair the short to battery voltage in the (K1) MAP Sensor Signal
→ Go To 4
No
4 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Connect a jumper wire between the (K1) MAP Sensor Signal circuit and the (K4)
Sensor ground circuit.
With the DRBIII , monitor the MAP Sensor voltage.
Turn the ignition on.
Is the voltage below 1.0 volt?
Yes → Replace the MAP Sensor.
→ Go To 5
No
5 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K1) MAP Sensor Signal circuit between the MAP
Sensor harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the open in the (K1) MAP Sensor Signal circuit.
No
6 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K4) Sensor ground circuit between the MAP Sensor
harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 7
→ Repair the open in the (K4) Sensor ground circuit.
No
7 NOTE: Before Continuing: Disconnect the PCM harness connector and
check the related wiring terminals for corrosion, damage or terminal push
out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
