Test Description

WARNING: This page is about a different car, the 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The number below refer to the step number on the diagnostic procedure.

6

This step indicates this sensor is currently functioning correctly. If you were sent to this diagnostic procedure from other service information return to that procedure now.

7

This step isolates the signal circuit from the other possible causes of the DTC condition.

8

This step determines if the 5-volt reference circuit has the proper voltage. The amperage available on the 5-volt reference circuit should be about 180 mA.

9

This step determines if the signal circuit is shorted to voltage or open.

10

This step determines if the sensor ground circuit has good continuity. With the TP signal circuit (5 volts) grounded through the sensor ground circuit terminal, very little voltage should be available at TP signal circuit.
