THROTTLE BODY 6P CONNECTOR VCC3 (BLU)
TP Sensor A Circuit Low Voltage
NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Check TP SENSOR A in the DATA LIST with the HDS.
Go to step 4.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the throttle body and the ECM/PCM.
4. Check for Temporary DTCs or DTCs with the HDS.
Go to step 10.
Go to step 5.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the throttle body 6P connector.
7. Jump the SCS line with the HDS.
8. Disconnect ECM/PCM connector C (44P). 9. Check for continuity between throttle body 6P
connector terminal No. 1 and body ground.
Repair short in the wire between the throttle
body and the ECM/PCM (C20), then go to step 18.
Go to step 23.
10. Measure the voltage between throttle body 6P connector terminal No. 2 and body ground.
Go to step 16.
Go to step 11.

11. Turn the ignition switch to LOCK (0).
12. Jump the SCS line with the HDS.
13. Disconnect ECM/PCM connector C (44P).
14. Disconnect the throttle body 6P connector.
15. Check for continuity between ECM/PCM connector
terminal C12 and throttle body 6P connector
terminal No. 2.
Go to step 23.
Repair open in the wire between the throttle
body and the ECM/PCM (C12), then go to step 18. 16. Turn the ignition switch to LOCK (0).
17. Replace the throttle body; K20Z2 engine (see page
11-348), K20Z3 engine (see page 11-349).
18. Reconnect all connectors.
19. Turn the ignition switch to ON (II).
20. Reset the ECM/PCM with the HDS.
21. Do the ECM/PCM idle learn procedure (see page 11-310).
22. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the throttle body and the ECM/PCM,
then go to step 1.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
23. Reconnect all connectors.
24. Update the ECM/PCM if it does not have the latest software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
25. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the throttle body and the ECM/PCM. If
the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then recheck. If the
ECM/PCM was substituted, go to step 1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting.
