ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT AIR CONDITIONING PRESSURE SENSOR

(a) Check the wire harness.

(1) Disconnect the A51 air conditioner pressure sensor connector.

(2) Disconnect the H25 air conditioning amplifier assembly connector.

(3) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

A51-1 (-) - H25-15 (SG-4)

Always

Below 1 Ω

A51-2 (PR) - H25-6 (PRE)

Always

Below 1 Ω

A51-3 (+) - H25-11 (S5-3)

Always

Below 1 Ω

A51-1 (-) - Body ground

Always

10 kΩ or higher

H25-15 (SG-4) - Body ground

Always

10 kΩ or higher

A51-2 (PR) - Body ground

Always

10 kΩ or higher

H25-6 (PRE) - Body ground

Always

10 kΩ or higher

A51-3 (+) - Body ground

Always

10 kΩ or higher

H25-11 (S5-3) - Body ground

Always

10 kΩ or higher

If the resistance is not as specified, repair the wire harness.

    WARNING

    When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it

    Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.
