OBD-II (EN): Throttle Position Sensor (TPS) Output Circuit Open
Code P2620 indicates a problem with the throttle position sensor (TPS) output circuit – the engine control module is not receiving the correct signal indicating the throttle opening angle. The cause could be a faulty sensor, a broken wiring harness, or a power supply problem in the circuit. We recommend diagnosis by a specialist as soon as possible, as the fault can cause engine hesitation and put the vehicle into limp mode.
Symptoms
Check Engine Light is on the dashboard Engine power limitation or entry into limp mode Engine runs rough or hesitates during acceleration Acceleration is unpredictable or delayed Possible difficulty starting the engine Increased fuel consumption
Possible causes
Faulty or worn throttle position sensor (TPS) Open or short circuit in the TPS sensor wiring harness Damaged throttle position sensor electrical connector Engine control module (ECM/PCM) defect – rare Carbon buildup or contamination on the throttle body affecting the sensor potentiometer Low supply voltage or ground problem in the sensor circuit
