Trouble Ticket Help Requests for DTC P2121
Help Request Posted
2004 Lexus ES330 3.3L MIL Lamp on VIN: JTHBA30G44
P2121: Throttle Pedal Position Sensor/Switch 'D' Circuit Malfunction. Check engine sign lights on with TRAC OFF and VSC sign. I could not find any TSB and cases at iATN. Can I just replace the TPS? The TPS looks mounted with revets to the throttle body. I hope to get pin point solution. Thanks in advance.
