How do I fix code P0120?
What repairs can fix the P0120 code?
- Repairing or replacing the TPS connector.
- Repairing the wiring as necessary.
- Replacing the TPS with a new sensor.
Where is the throttle pedal position sensor switch A?
The Throttle Position Sensor/Switch is located on the Throttle Body of the Intake Manifold and the Pedal Position Sensor/Switch is part of the Accelerator Pedal assembly. These sensors provide precise input from the driver’s foot in terms of how MUCH power is needed from the engine and, how URGENTLY power is needed.
How do I know if my throttle position switch is bad?
Symptoms of a Bad or Failing Throttle Position Sensor
- Car won’t accelerate, lacks power when accelerating, or accelerates itself.
- Engine won’t idle smoothly, idles too slowly, or stalls.
- Car accelerates, but won’t exceed a relatively low speed, or shift up.
How much is a throttle pedal position sensor?
The average cost for throttle position sensor replacement is between $155 and $199. Labor costs are estimated between $54 and $69 while parts are priced between $100 and $130.
What does p0120 mean on the TPS sensor?
P0120 Meaning. The throttle position sensor (TPS) responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM).
When to set the Opel p0120 throttle pedal sensor?
At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is outside of normal operating range, P0120 Opel will set. NOTE: The PCM knows that any large change in throttle position means a cooresponding change in manifold pressure (MAP).
What causes the p0120 OBD-II trouble code?
Throttle Pedal Position Sensor/Switch (TPS) “A” Circuit Malfunction P0120 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS sensor circuit A output voltage going below or above the sensor’s expected range, or is chattering when compared to TPS sensor circuit B. What causes the P0120 code?
What does code p0120 mean on ECT system?
Code P0120 will most likely trigger the “Check Engine Light.” Aside from that, here are some of the symptoms you should watch for: An illuminated check engine light is a common symptom of the error code P0120. Again, the code P0120 is not an issue you can disregard, especially if your vehicle relies on ECT systems.
