DTC P1122: TP Sensor Signal Higher Than Expected
- Turn the ignition switch ON (II).
- Check the throttle position with the scan tool or the HDS.
Is 12.6%, 0.6 V, or less indicated when the throttle is fully closed?
- YES - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the TP sensor and at the ECM/PCM.
- NO - Replace the TP sensor (the TP sensor is not available separately) (see THROTTLE BODY DISASSEMBLY/REASSEMBLY ).
