ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT AIR CONDITIONER PRESSURE SENSOR (for Automatic Air Conditioning System)
(a) Check the wire harness.
(1) Disconnect the A34 air conditioner pressure sensor connector.
(2) Disconnect the A35 and A36 air conditioning amplifier assembly connector.
(3) Measure the resistance according to the value(s) in the table below. Text in Illustration
Standard Resistance:
If the resistance is not as specified, repair the wire harness. |
|
(4) Connect the A35 and A36 air conditioning amplifier assembly connector.
(5) Measure the voltage according to the value(s) in the table below. Text in Illustration
Standard Voltage:
If the voltage is not as specified, repair the wire harness or replace the air conditioning amplifier assembly. |
|
(b) Check the air conditioner pressure sensor.
(1) Install a manifold gauge set.
(2) Connect the A34 air conditioner pressure sensor connector.
(3) Warm up the engine.
(4) A/C switch on.
(5) Measure the voltage according to the value(s) in the table below. Text in Illustration
Standard Voltage:
If the voltage is not as specified, replace the air conditioner pressure sensor. |
