P0914 – OBD-II Trouble Code Technical Description

Shift Position Circuit

What does the fault code mean P0914?

OBD2 Diagnostic Trouble Code P0914 indicates a problem in the shift position circuit. The automated manual/semi-automatic transmission allows for faster gear changes thanks to the electric motor that controls the gear shift drive. If a P0914 code persists, it indicates problems detected in the transmission's GSP drive circuit and may also be associated with other related trouble codes such as P0915, P0916, P0917, and P0918.

Possible reasons

The most common causes of a P0914 trouble code are damaged or faulty transmission positioning system wiring, connectors, or components. This code can also be caused by blown fuses, a short to ground in the battery, or a faulty PCM.

What are the symptoms of a fault code? P0914?

Symptoms associated with a P0914 code include:

  • Late, abrupt or erratic shifts.
  • Transmission gets stuck in gear.
  • Failed to engage the gear.

Additionally, this code may be accompanied by harsh gear shifting and decreased fuel efficiency in the vehicle.

How to diagnose a fault code P0914?

To diagnose and resolve the P0914 trouble code, a mechanic should perform the following steps:

  1. Carefully inspect all cables, connectors and components for damage.
  2. Clear the code and check the vehicle to see if the code returns.
  3. If the code returns, download all freeze frame data and stored codes for further diagnosis.
  4. Check the voltage and ground signal in the gear position circuit using a digital voltmeter.
  5. If there is no voltage signal or ground, disconnect the PCM and other associated control modules, then check the continuity of the gear position circuit with battery ground.
  6. Check the gearshift shaft and gearbox guide for damage.
  7. If necessary, suspect a faulty PCM.
  8. Inspect and test the PCM to determine if it is faulty or requires reprogramming.
  9. Clean up the code and retest the system to ensure the code returns.

Diagnostic errors

Common errors when diagnosing a P0914 code may include:

  1. Insufficient attention to testing and inspection of all connections, cables and components associated with the gear shift system.
  2. Incorrect interpretation of scanner data or insufficient use of diagnostic equipment, which may lead to an incorrect diagnosis of the problem.
  3. Failure to fully test and diagnose all gear position chain related components may result in incorrect repair or replacement of components.

How serious is the fault code? P0914?

Trouble code P0914 indicates problems with the shift position circuit, which can seriously affect the performance of the vehicle's transmission. This can result in delayed or harsh gear changes and difficulty engaging gears. If the P0914 code is ignored or not corrected, it can lead to further damage to the transmission system and increased repair costs. It is recommended that you contact a professional auto mechanic to accurately diagnose and fix the problem.

What repair will help eliminate the code? P0914?

Trouble code P0914 may require the following steps to resolve:

  1. Inspect and repair or replace damaged wires, connectors, or components associated with the gear positioning system.
  2. Replacing blown fuses or correcting a short to ground battery.
  3. Check and, if necessary, replace the faulty PCM (engine control module).
  4. Inspect and repair or replace the shift actuator or other associated components such as the sensor or shift assembly.

It is necessary to contact an experienced auto mechanic to conduct a detailed diagnosis and eliminate the cause of the P0914 fault code.
