P0926 Fault Code

P0926 OBD-II Trouble Code Short Description

Gear Shift Reverse Actuator Circuit Low

What does trouble code P0926 mean?

The P0926 fault code indicates a problem within the gear shift reverse actuator circuit. This code is triggered when the engine control module (ECM) detects that the voltage in the actuator circuit is lower than expected, preventing proper gear shifting functionality, especially in reverse.

Symptoms

What are the symptoms of the P0926 code?

Common symptoms associated with the P0926 code may include:

  • Inability to shift into reverse gear.
  • Erratic or unresponsive gear shifting.
  • Warning lights on the dashboard, specifically indicating transmission issues.
  • Unusual noises when attempting to shift into reverse.

Causes

What causes the P0926 code?

Several factors can lead to this fault code, including:

  • Damaged wiring or connectors related to the gear shift reverse actuator.
  • A faulty reverse actuator itself, causing it to malfunction.
  • Issues with the ECM, potentially failing to send the correct signals.
  • Poor electrical connections that lead to intermittent operation.

Possible Solutions

How to fix P0926?

To address the P0926 fault code, consider the following steps:

  1. Inspect the wiring and connectors for signs of damage or corrosion and repair as necessary.
  2. Test the reverse actuator for function, replacing it if it's found to be faulty.
  3. Check for proper voltage and ground at the actuator connector to ensure appropriate electrical supply.
  4. Clear the code and perform a road test to see if the issue persists. If it returns, further diagnosis may be needed to evaluate the ECM or other related components.
