P0929 OBD-II: Gear Shift Lock Solenoid/Actuator Control Circuit "A"
P0929 Severity
Will P0929 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0929?
The Transmission is responsible for converting the power produced by the engine to movement of the vehicle. The transmission has its own control module (TCM). The TCM uses solenoids to control the fluid pressure that activates the different gears inside the transmission. If the TCM sees an implausible signal from the shift solenoid, code P0929 will be set.
