What Does P092C Mean?
The TCM or PCM has detected a lower-than-expected voltage on the gear shift lock solenoid/actuator control circuit B. This indicates a short to ground, excessive circuit resistance causing voltage drop, or a partially grounded solenoid coil. The low voltage prevents the solenoid from generating sufficient electromagnetic force to properly actuate the shift lock mechanism.
Common Causes
30%
Short to ground in the circuit B wiring between the control module and solenoid
25%
Corroded or water-damaged connector causing low resistance path to ground
20%
Shift lock solenoid B with partially shorted coil windings
15%
Damaged wiring insulation in the center console area where liquids may collect
10%
Faulty control module output driver pulling the circuit low
Diagnostic Steps
1
Disconnect the shift lock solenoid B connector and measure the circuit voltage at the harness side; if voltage returns to normal, the solenoid itself is the issue.
2
With the solenoid disconnected, check for continuity between the circuit B wire and chassis ground; continuity indicates a short to ground in the wiring.
3
Inspect the wiring harness in the center console area for damage from spills, debris, or mechanical abrasion.
4
Measure the solenoid coil resistance; a value significantly below specification indicates shorted coil windings.
5
If the wiring and solenoid are clean, check the control module output by commanding the solenoid and measuring the voltage at the module connector.

The most common cause of P092C (Gear Shift Lock Solenoid/Actuator Control Circuit "B" Low) is: Short to ground in the circuit B wiring between the control module and solenoid
Typical repair costs for P092C range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A low voltage on the shift lock circuit prevents proper solenoid engagement, which may allow the shifter to be moved from Park without meeting safety conditions, or the solenoid may draw excessive current and damage the control module driver.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P092C to identify the root cause.
