The P0927 fault code indicates the Engine Control Module (ECM) detected a problem in the operation of the gear shift reverse actuator of the transmission. The gear shift reverse actuator controls how a vehicle’s transmission shifts into reverse gear.

What the P0927 code means

Put in the simplest of terms, the P0927 OBD-II trouble code means the ECM found a signal indicating the voltage within the gear shift reverse actuator was higher than normal parameters.

This voltage anomaly may be caused by improper function of the guide rail or shift shaft corresponding to reverse gear within the transmission, making it difficult or impossible to shift into reverse gear.

What causes the P0927 code?

While there are several issues that can trigger a higher than normal reading within the gear shift reverse actuator circuit, resulting in the illumination of the Check Engine Light on a vehicle’s dashboard, the cause of the code is likely due to a mechanical problem within the transmission.

Common mistakes when diagnosing the P0927 code

After the P0927 code registers, a technician may make the following mistake(s):

  • Failure to visually inspect the transmission, especially components relating to reverse gear
  • Forgetting to clear the P0927 OBD-II fault code after the issue is resolved

How serious is the P0927 code?

A vehicle registering the P0927 code can still run, although it may not be able to shift into reverse gear easily or at all. Over time, this issue can affect the function of other parts and systems, so it is advisable to promptly contact a qualified mechanic for assistance in diagnosing and repairing the root cause of the P0927 code registering.

What repairs can fix the P0927 code?

  • Adjusting the guide rail or shift shaft corresponding to reverse gear
  • Replacing the transmission as a whole
  • Replacing the ECM in rare cases
