DTC Troubleshooting: P0222 (7)

DTC P0222:
TP Sensor B Circuit Low Voltage
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.

1. Turn the ignition switch to ON (II).

1. Clear the DTC with the HDS.

1. Check TP SENSOR B in the DATA LIST with the HDS.

Is there about 0.3 V or less?

YES | - | Go to Step 4 .
NO | - | Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the throttle body and the ECM/PCM.■

1. Check for Temporary DTCs or DTCs with the HDS.

Are DTC P0122 and P0222 indicated at the same time?

YES | - | Go to Step 10 .
NO | - | Go to Step 5 .

1. Turn the ignition switch to LOCK (0).

1. Disconnect the throttle body 6P connector.

1. Jump the SCS line with the HDS.

1. Disconnect ECM/PCM connector C (44P).

1. Check for continuity between throttle body 6P connector terminal No. 3 and body ground.

Is there continuity?

YES | - | Repair short in the wire between the throttle body and the ECM/PCM (C21), then go to Step 18 .
NO | - | Go to Step 23 .

1. Measure the voltage between throttle body 6P connector terminal No. 2 and body ground.

Is there about 5 V?

YES | - | Go to Step 16 .
NO | - | Go to Step 11 .

1. Turn the ignition switch to LOCK (0).

1. Jump the SCS line with the HDS.

1. Disconnect ECM/PCM connector C (44P).

1. Disconnect the throttle body 6P connector.

1. Check for continuity between ECM/PCM connector terminal C12 and throttle body 6P connector terminal No. 2.

Is there continuity?

YES | - | Go to Step 23 .
NO | - | Repair open in the wire between the throttle body and the ECM/PCM (C12), then go to Step 18 .

1. Turn the ignition switch to LOCK (0).

1. Replace the throttle body.

1. Reconnect all connectors.

1. Turn the ignition switch to ON (II).

1. Reset the ECM/PCM with the HDS.

1. Do the ECM/PCM idle learn procedure.

1. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0222 indicated?

YES | - | Check for poor connections or loose terminals at the throttle body and the ECM/PCM, then go to Step 1 .
NO | - | Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.■

1. Reconnect all connectors.

1. Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM.

1. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0222 indicated?

YES | - | 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, then recheck. If the ECM/PCM was substituted, go to Step 1 .
NO | - | If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.■
