Common questions

Why does the throttle position sensor Get Low voltage?

Why does the throttle position sensor Get Low voltage?

The voltage of the throttle position sensor can drop below the expected range for several reasons, including the following: A loosely-mounted throttle position sensor. Electrical short on the sensor circuit, either to the ground or to another wire. Bad or corroded wiring or connections for the sensor.

How do I fix code P0120?

What repairs can fix the P0120 code?

  1. Repairing or replacing the TPS connector.
  2. Repairing the wiring as necessary.
  3. Replacing the TPS with a new sensor.

Can a bad throttle position sensor affect transmission?

The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.

How do I fix error code P2122?

What repairs can fix the P2122 code?

  1. Replacing or repositioning a ground wire.
  2. Replacing the wiring and/or connectors in the CAN bus harness or throttle actuator motor.
  3. Replacing the throttle position sensor, the throttle actuator control motor, the throttle position actuator, or the pedal position sensor.

What could cause a P0120 code?

To give you an idea, here are the possible causes of the P0120 code: Faulty throttle position sensor. Faulty accelerator position sensor. Damaged or corroded wiring or connectors.

What does a p2122 diagnostic trouble code mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. A P2122 code means that the the car’s computer has detected that the TPS (throttle position sensor) is reporting too low a voltage.

What was the cause of the p2122 Chevy accident?

P2122 CHEVROLET Possible Causes 1 Faulty Accelerator Pedal Position Sensor 2 Accelerator Pedal Position Sensor harness is open or shorted 3 Accelerator Pedal Position Sensor circuit poor electrical connection 4 Faulty Electric Throttle Control Actuator

What is the p2138 code on a Chevy Malibu?

P2138 is a common issue among the following makes: Chevrolet (especially on a Chevy Malibu), Nissan, Honda, Subaru, and Acura. Accelerator pedal position (APP) sensors provide information to the ECM/PCM concerning driver throttle requests. The ECM/PCM processes that information very rapidly, mirroring pedal movement by moving the throttle plate.

When do I get a p2138 problem code?

The P2138 trouble code is triggered when there are problems with the throttle/pedal position sensor/switch. However, it’s not the only code related to the throttle body and its circuitry. The P2135, P2136, P2137, P2139, and P2140 DTCs also indicate issues in the same areas.
