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.

2

This step determines if the failure condition is present.

4

This step determines if an open sensor ground circuit condition is present. Since the FTP sensor and FTS sensor share a sensor ground, and open condition between the splice and the AF ECM would cause both signal circuits to indicate high voltage.

5

This step determines if an open or shorted signal circuit is the cause of the failure condition.

6

This step determines if a shorted 5-volt reference circuit is the cause of the failure condition.

7

This step determines if an open sensor ground circuit between the FTP connector and the circuit splice is the cause of the failure condition.
