P0913 - Gate select drive circuit high

P0913 – OBD-II Trouble Code Technical Description

High signal level in the gate selection drive circuit

What does the fault code mean P0913?

Error code P0913 indicates a high signal level in the gate select drive circuit. This causes the check engine light to come on. The choke selector actuator, located above the shift lever in manual transmissions, plays an important role in gear shifting. If the gate select actuator is not responding, code P0913 will appear. The ECU activates the electric motor to engage gears using data from the sensors. A high signal in the gate select drive circuit causes fault P0913 to persist.

Possible reasons

The most common problems that cause the P0913 code to appear include faulty wiring and blown or faulty fuses. In rare cases, a faulty PCM can also cause a P0913 code to persist.

What are the symptoms of a fault code? P0913?

Key symptoms associated with a P0913 code include:

• Slow acceleration and idling.
• Difficulties when changing gears.
• Reduced vehicle fuel efficiency.

How to diagnose a fault code P0913?

To diagnose error code P0913, you need to follow these steps:

1. Use an advanced OBD-II scanner and digital volt/ohm meter to begin the diagnostic procedure.
2. Visually check all wiring, connectors and electrical components associated with the shift lever.
3. Load freeze frame data or stored trouble codes for further diagnosis.
4. Make sure the order of the stored codes is registered correctly.
5. Check the voltage and ground on the gate select motor circuit using a digital volt/ohmmeter.
6. Disconnect the PCM and associated control modules if no signal is detected to avoid further damage.
7. Check the continuity and grounding of the gate select motor switch using a volt/ohmmeter.
8. Check fuses for blown or loose fuses.
9. Check the PCM for problems or need reprogramming.
10. Clean up the code and retest the system to see if the code reappears.

Diagnostic errors

Common errors when diagnosing a P0913 code include:

1. Misuse or underuse of diagnostic equipment, which may lead to incorrect interpretation of data.
2. Insufficient inspection of all electrical components and wiring may result in missing the root cause of the problem.
3. Incorrect interpretation of scanner data, including errors in decoding fault codes, which may lead to incorrect repair or replacement of components.
4. Failure to fully test the system after repair actions have been carried out, which may result in the P0913 error code reoccurring.

How serious is the fault code? P0913?

Trouble code P0913 can be serious because it indicates problems with the transmission gate position actuator. This can cause difficulty shifting gears and affect the overall performance of the vehicle. If ignored or not properly diagnosed and repaired, this problem can lead to poor transmission performance and additional damage to the system. It is recommended that you contact a qualified mechanic to diagnose and correct the problem to avoid possible serious consequences.

What repair will help eliminate the code? P0913?

The following repair steps may be required to resolve the P0913 code:

1. Replace or repair damaged wiring and electrical connections associated with the shift lever.
2. Replace or restore damaged or blown fuses.
3. Check and, if necessary, replace the faulty PCM (engine control module).
4. Check and, if necessary, replace the shift assembly or other related components, such as the clutch position sensor or clutch actuator.

It is important to contact a professional auto mechanic to accurately diagnose the problem and properly repair the problem to avoid the reoccurrence of the P0913 code.
