Car Diagnostic Trouble Code (DTC) P0122: Throttle Position Sensor Circuit Low Input
What does the P0122 DTC indicate?
The P0122 DTC means ________.
Answer:
A P0122 DTC indicates a problem with the Throttle Position Sensor circuit, suggesting a low input which could be due to a faulty sensor or issues with the circuit.
When a P0122 Diagnostic Trouble Code (DTC) is retrieved using a scan tool, it signifies that there is an issue with the Throttle Position Sensor (TPS) circuit. This particular code points towards a low input in the TPS circuit, indicating that there may be a problem with the sensor itself or with the circuit it is connected to.
The Throttle Position Sensor is responsible for measuring the angle of the throttle and sending this information to the engine control unit (ECU). When the TPS circuit shows a low input, it suggests that the sensor is not functioning as it should or that there are underlying issues with the wiring or connections.
Addressing a P0122 code typically involves inspecting the TPS, its connectors, and the wiring associated with it. Depending on the findings, it may be necessary to replace the sensor with a new component if it is found to be defective.
Possible Causes and Solutions:- Inspect the TPS connector for corrosion or damage, and clean or repair as necessary.
- Check the TPS wiring for signs of wear, abrasion, or breaks, and repair if needed.
- Test the TPS itself with a multimeter, following the manufacturer's specifications.
- If the TPS is defective, replace it with a new component.
