A/C PRESSURE SENSOR CIRCUIT (CONTINUED)
10.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE A/C PRESSURE SENSOR SIGNAL
CIRCUIT
Turn the ignition off.
Disconnect the A/C Heater Control Module harness connector.
Note: Check connector - Clean/repair as necessary.
Measure the resistance between ground and the A/C Pressure Sensor
Signal circuit in the A/C Pressure Sensor harness connector.
Is the resistance below 100 ohms?
Yes >> Repair the A/C Pressure Sensor Signal circuit for a short
to ground.
Perform BODY VERIFICATION TEST.
No >> Go to 11
11.
MEASURE THE RESISTANCE FROM THE A/C PRESSURE SENSOR SIGNAL CIRCUIT TO THE SENSOR
GROUND CIRCUIT
With the ignition off.
Measure the resistance from the A/C Pressure Sensor Signal circuit to
the Sensor Ground circuit at the A/C Pressure Sensor harness con-
nector.
Is the resistance below 100 ohms?
Yes >> Repair the A/C Pressure Sensor Signal circuit for a short
to the Sensor Ground circuit.
Perform BODY VERIFICATION TEST.
No >> Replace the A/C Heater Control Module. (Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS/HEATER
CONTROL - REMOVAL).
Perform BODY VERIFICATION TEST.
12.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE A/C PRESSURE SENSOR 5-VOLT
SUPPLY CIRCUIT
Turn the ignition off.
Disconnect the A/C Heater Control Module harness connector.
Measure the resistance between ground and the 5-Volt Supply circuit
at the A/C Pressure Sensor harness connector.
Is the resistance below 100 ohms?
Yes >> Repair the 5-Volt Supply circuit for a short to ground.
Perform BODY VERIFICATION TEST.
No >> Go to 13
