What Does P092D Mean?
The TCM or PCM has detected a higher-than-expected voltage on the gear shift lock solenoid/actuator control circuit B. This typically indicates a short to battery voltage in the circuit or a stuck relay providing constant power to the solenoid. The high voltage may cause the solenoid to remain continuously energized or may interfere with proper control module management of the shift lock function.
Common Causes
30%
Short to battery voltage in the circuit B wiring
25%
Shift lock solenoid relay stuck closed or welded contacts
20%
Wiring harness chafed against a power feed wire in the console or underdash area
15%
Faulty control module with an internally shorted high-side driver
10%
Incorrect wiring after a previous repair or aftermarket installation
Diagnostic Steps
1
Disconnect the shift lock solenoid B and measure voltage on the circuit B wire with the key on; battery voltage present with the solenoid disconnected confirms a wiring short to power.
2
Trace the circuit B wiring through the console and underdash area looking for chafing against power wires or sharp edges.
3
If a relay controls the solenoid power, remove and test the relay for stuck or welded contacts.
4
Check the control module connector for bent pins or signs of overheating that could indicate a shorted driver circuit.
5
Verify no aftermarket installations (alarm, remote start, etc.) have tapped into or mis-routed the shift lock wiring.

The most common cause of P092D (Gear Shift Lock Solenoid/Actuator Control Circuit "B" High) is: Short to battery voltage in the circuit B wiring
Typical repair costs for P092D range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A continuously energized shift lock solenoid may overheat and fail, or it may prevent the control module from properly managing the park interlock sequence. Additionally, a shorted circuit can cause fuse blows that may affect other systems sharing the same fuse.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P092D to identify the root cause.
