Component Testing

1. Ignition OFF, disconnect the harness connector at the B65 Intake Manifold Pressure and Air Temperature sensor.

Note: A thermometer can be used to test the sensor off the vehicle.

2. Test the IAT sensor by varying the sensor temperature while monitoring the sensor resistance. Compare the readings with the Temperature

Versus Resistance - Intake Air Temperature Sensor (See: Powertrain Management/Computers and Control

Systems/Specifications/Temperature Versus Resistance - Intake Air Temperature Sensor) table and verify that the resistance is within 5 % of

the specification.

瀚慖f not within the specified range, replace the B65 Intake Manifold Pressure and Air Temperature sensor.
