P1598-A/C PRESSURE SENSOR VOLTS TOO HIGH —
TEST
3 Turn the ignition off.
Disconnect the A/C Pressure Sensor harness connector.
Turn the ignition on.
Measure the voltage on the A/C Pressure Sensor Signal circuit at the A/C Pressure
Sensor harness connector.
Is the voltage above 5.2 volts?
Yes → Repair the A/C Pressure Sensor Signal circuit for a short to
→ Go To 4
No
4 Turn the ignition off.
Disconnect the A/C Pressure Sensor harness connector.
Connect a jumper wire between the A/C Pressure Sensor Signal circuit and the
Sensor ground circuit.
With the DRBIII , monitor the A/C Pressure Sensor voltage.
Turn the ignition on.
Is the voltage below 1.0 volt?
Yes → Replace the A/C Pressure Sensor.
→ Go To 5
No
5 Turn the ignition off.
Disconnect the A/C Pressure Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the A/C Pressure Sensor Signal circuit between the PCM
harness connector and the A/C Pressure Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the A/C Pressure Sensor Signal circuit for an open.
No
6 Turn the ignition off.
Disconnect the A/C Pressure Sensor harness connector.
Measure the resistance between ground and the Sensor ground circuit at the A/C
Pressure Sensor harness connector.
Is the resistance below 30 ohms?
Yes → Go To 7
→ Repair the Sensor ground circuit for an open.
No
7 If there are no possible causes remaining, view repair.
