Pressure Switch

TESTING

Sedan, Coupe, Loyale, XT, Wagon and Brat

1. Disconnect the pressure switch wire harness.
2. Connect an ohmmeter between the terminals of the pressure switch.
3. Verify that the pressure switch resistance is at least 1 megohm minimum when the compressor tank pressure is approximately 132–147 (910–1014 kPa).
4. Release the compressor tank pressure slowly, and verify that there is no resistance at the pressure switch terminals when the tank pressure reaches approximately 125 psi (862 kPa).
5. If not as specified, replace the pressure switch.

Legacy

1. Disconnect the pressure switch wire harness.
2. Connect an ohmmeter between the terminals of the pressure switch.
3. Verify the pressure switch resistance is at least 1 megohm when the compressor tank pressure is approximately 137 psi (945 kPa).
4. Release the compressor tank pressure slowly and verify that there is no resistance at the pressure switch terminals when the tank pressure reaches approximately 111 psi (765 kPa).
5. If not as specified, replace the pressure switch.
