DIAGNOSTIC CODE 5-2

Checking for a bad pedal connection

1.Reconnect the TPS.

2.Turn the ignition key to the ON position.

If code 5-2 is still active, proceed to Test 32. If code 5-2 is not present, harness connector pin C is loose (either in the sensor or connector). Repair the loose connection. Retest to be sure the problem has been corrected.

If there is now an active fault, code 5-1, there is poor contact in the sensor connector mating pins. Repair the loose connections. Retest to be sure the problem has been corrected.

Test 17

Checking for an open in the ground line in the harness

1.Disconnect the J1B connector from the V-MAC II module.

2.Connect a jumper from harness connector pin C to a good ground.

3.Check for continuity from J1B connector pin L3 (the TPS ground [ ] line) to a good ground.

If there is continuity, proceed to Test 34.

If there is no continuity, there is an open in the ground line in the harness. Locate and repair the open. Retest to be sure the problem has been corrected.

Test 18

Checking for pin-to-pin continuity with the ground line

1.Disconnect the serial link jumper.

2.Disconnect the J1A and J2 connectors from the V-MAC II module.

3.Check for continuity between J1B connector pin L3 (the TPS ground [ ] line) and each of the other pins (one at a time) on the J1A, J1B and J2 connectors.

If there is continuity with another pin, there is a pin-to-pin short between the TPS ground line and the pin which showed continuity. Locate and repairtheshortandreplacetheV-MACIImodule. Retest to be sure the problem has been corrected.

If there is no continuity, replace the V-MAC II module. Retest to be sure the problem has been corrected.
