DTC Troubleshooting: P0122 (7)

DTC P0122: TP Sensor A Circuit Low Voltage Turn the ignition switch ON (II). Clear the DTC with the HDS. Check TP SENSOR-A in the DATA LIST with the HDS. Is there about 0.3 V or less?
YES | - | Go to Step 4 .
NO | - | Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the throttle body and the throttle actuator control module.■
Check for Temporary DTCs or DTCs in the DTCs MENU with the HDS. Are DTC P0122 and P0222 indicated at the same time?
YES | - | Go to Step 9 .
NO | - | Go to Step 5 .
Turn the ignition switch OFF. Disconnect the throttle body 6P connector. Disconnect the throttle actuator control module 16P connector. Check for continuity between throttle body 6P connector terminal No. 1 and body ground. Is there continuity?
YES | - | Repair short in the wire between the throttle body and the throttle actuator control module (TPSA line), then go to Step 17 .
NO | - | Substitute a known-good throttle actuator control module, then go to Step 17 and recheck. If DTC P0122 is not indicated, replace the original throttle actuator control module, then go to Step 17 . If DTC P0122 is indicated, go to Step 15 .

Measure voltage between throttle body 6P connector terminal No. 2 and body ground. Is there about 5 V?
YES | - | Go to Step 15 .
NO | - | Go to Step 10 .
Turn the ignition switch OFF. Disconnect the throttle actuator control module 16P connector. Disconnect the throttle body 6P connector. |

Connect throttle body 6P connector terminal No. 2 to body ground with a jumper wire. |

Check for continuity between throttle actuator control module 16P connector terminal No. 11 and body ground. Is there continuity?
YES | - | Substitute a known-good throttle actuator control module, then go to Step 17 and recheck. If DTC P0122 is not indicated, replace the original throttle actuator control module, then go to Step 17 . If DTC P0122 is indicated, go to Step 15 .
NO | - | Repair open in the wire between the throttle body and the throttle actuator control module (VCC line), then go to Step 17 .
Turn the ignition switch OFF. Replace the throttle body. Reconnect all connectors. Turn the ignition switch ON (II). Reset the ECM/PCM with the HDS. Do the ECM/PCM idle learn procedure. Check for Temporary DTCs or DTCs in the DTCs MENU with the HDS. Are any Temporary DTCs or DTCs indicated?
YES | - | If DTC P0122 is indicated, check for poor connections or loose terminals at the throttle body and the throttle actuator control module, then go to Step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO | - | Troubleshooting is complete.■
