P0922 code definition

The P0922 trouble code detects an electrical issue with the gear shift forward actuator circuit.

What the P0922 code means

The P0922 code is a standard OBD-II trouble code that notes a problem with the gear shift forward actuator circuit. The gear shift forward actuator is a critical part of an automatic transmission, and is responsible for actuating the shift into a forward-moving gear. When the powertrain control module (PCM), or the engine control module (ECM) detects an abnormally low voltage reading from the actuator circuit, then the P0925 trouble code will be stored.

What causes the P0922 code?

Potential causes of the P0922 trouble code include:

  • Defective gear shift forward actuator
  • Shorted wires, corroded connectors, or other damaged electrical components
  • Defective forward gear guide rail
  • Defective shift shaft
  • Mechanical malfunctions in the internal transmission
  • In rare cases, a faulty PCM, ECM, or transmission control module

What are the symptoms of the P0922 code?

The P0922 code will usually be accompanied by an illuminated Check Engine Light on the gauge cluster. It’s also possible that the car may have a hard time shifting into gear, or may be incapable of shifting into a forward-moving gear. If a forward gear is achieved, the car will likely be drivable, but fuel efficiency will probably be reduced.

How does a mechanic diagnose the P0922 code?

The P0922 code should be diagnosed with the help of an OBD-II trouble code scanner. A trustworthy mechanic will use the scanner to view the freeze frame data and assess the code. The mechanic will also check for the presence of any other trouble codes. If multiple codes are present, they should be addressed in the order in which they appear. The codes will then be reset, and the vehicle will be restarted, so the technician can see if the code remains detected. If not, then it is likely a case of an intermittent error, or perhaps an erroneously detected code.

If the P0922 code remains following the reset, then the mechanic will visually inspect the electrical components, replacing any wires, connectors, or fuses that are damaged or otherwise compromised. The gear shift forward actuator will then be inspected, followed by the shift shaft and the forward gear guide rail. If the issue remains unresolved, the mechanic will have to perform a more in depth inspection of the transmission, PCM, ECM, and transmission control module.

Whenever a component is replaced, the mechanic will need to pause the inspection, reset the trouble codes, and restart the vehicle again to see if the code remains. This helps the technician know as soon as the P0922 code has been resolved.

Common mistakes when diagnosing the P0922 code

The most frequently made diagnostic mistake with the P0922 code comes from a failure to adhere to the OBD-II trouble code diagnosis protocol. It is very important that the protocol be followed step by step, so that mechanics are able to complete diagnoses and repairs in an efficient and effective manner.

It is fairly common for simple electrical fixes to be overlooked in favor of more complex, erroneous repairs.

How serious is the P0922 code?

Vehicles with a P0922 trouble code will sometimes be drivable, but sometimes will not be, due to an inability to access a forward-moving gear. However, continuing to drive a vehicle that has a present P0922 code can result in serious damage to the transmission, so an inspection and repair should be scheduled as soon as possible.

What repairs can fix the P0922 code?

Potential repairs for the P0922 trouble code include:

  • Replacement of the gear shift forward actuator
  • Replacement of electrical components in the system
  • Replacement or repair of the forward gear guide rail
  • Replacement or repair of the shift shaft
  • In rare cases, replacement of the PCM, ECM, or transmission control module

Additional comments for consideration regarding the P0922 code

The PCM or any other control module should only be replaced if all other possible causes have been thoroughly inspected. In the rare event that one of the control modules does require replacement, it will also require a reprogramming.

Michael was awesome. He let me watch and explained what was going on. Fixed a leak in the transmission line and the car ran perfectly instead of slipping in and out of gear. I was also low on ATF fluid because of the leak so we put that in. He also tightened up the belt which was making my stearing wheel squeak. And he also helped me change my wiper blades lol There were 7 transmission codes when he first plugged the computer in. When he was done, all the codes went away! There is one more part needed so we made a separate appointment for tomorrow. I thought I was going to lose my car, but as it turns out, my car is fine! It's amazing what a leak and lack of fluid does to the functioning of your transmission. So many people (non mechanics) thought my transmission was bad and I probably would need a new one. Nope! Just fix the leak and get the fluid in there  Yay! 
