Causes of the Dodge p0122 OBD Code

P0122 in a Dodge typically indicates a problem with the throttle position sensor circuit low voltage.

P0122 can be caused by a faulty throttle position sensor.
A throttle position sensor harness that is open or shorted.
A throttle position sensor circuit with poor electrical connection.
A faulty Powertrain Control Module (PCM).

Fixing Dodge Error Code p0122 Step By Step

Address the low voltage issue in the throttle position sensor circuit on a Dodge with code P0122.

To fix a Dodge OBDII code p0122, start by reviewing the ‘Possible Causes’ mentioned above and visually examining the corresponding wiring harness and connectors.
Check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
If the wiring and connectors appear to be in good condition, proceed to test the throttle position sensor (TPS) using a multimeter to ensure it is functioning correctly.
If the TPS is faulty, replace it with a new one following the manufacturer’s guidelines.
After replacing the TPS, clear the fault codes using an OBDII scanner and test drive the vehicle to verify that the issue has been resolved.

Cost Of Fixing Dodge p0122 Fault Code

Diagnosing and repairing Dodge code P0122 involves testing and potentially replacing the throttle position sensor.

The cost to diagnose and fix a Dodge OBD code P0122 typically ranges from $75 to $150, with an estimated repair time of 1. 0 hour.

Costs depend on shop rates, complexity of the issue, and any additional parts needed for the repair.

Details of the Dodge p0122 OBD Code

Dodge fault code P0122 indicates an issue with the throttle position sensor circuit low voltage.

Dodge OBD code P0122 means that the Engine Control Module (ECM) has detected a low voltage condition in the Throttle Position Sensor (TPS) circuit.

The TPS is the component that triggers this fault code.

This sensor provides the ECM with information about the position of the throttle plate.

When the voltage signal from the TPS falls below a specified range, the ECM sets code P0122. This code is related to the throttle control system and can lead to drivability issues such as lack of power or poor acceleration.

Mechanic’s Tech Notes

Detailed information on Dodge code P0122, which indicates an issue with the throttle position sensor circuit low voltage.

To diagnose and fix OBDII code P0122 on a Dodge, start by checking the throttle position sensor (TPS) circuit.

Use a voltmeter to test the TPS signal voltage with the key on, engine off.

It should read around 0. 5 volts.

Next, slowly open the throttle and observe the voltage increase smoothly.

If the voltage spikes or drops out, the TPS may be faulty and need replacement.

Additionally, inspect the TPS wiring and connector for any damage or corrosion.

Clear the code after repairs and recheck to ensure the issue is resolved.

If the problem persists, further diagnosis with a scan tool may be necessary to pinpoint the exact cause.
