What Does P092A Mean?
The TCM or PCM has detected an open circuit in the gear shift lock solenoid/actuator control circuit B. In vehicles with dual shift lock circuits, circuit B typically provides a secondary or redundant lock function. An open circuit means this solenoid or actuator cannot be energized, potentially compromising the secondary safety interlock for the gear selector.
Common Causes
30%
Broken wire or disconnected connector in the shift lock solenoid circuit B
30%
Failed shift lock solenoid B with an open internal coil
20%
Corroded connector pins at the solenoid or control module
10%
Blown fuse in the circuit B power supply
10%
Faulty TCM or BCM driver circuit for shift lock solenoid B
Diagnostic Steps
1
Check all fuses related to the shift lock system and replace any that are blown.
2
Locate shift lock solenoid B (which may be separate from solenoid A or part of the same assembly) and inspect the connector for damage or disconnection.
3
Measure solenoid B coil resistance with an ohmmeter; infinite resistance confirms an open coil requiring solenoid replacement.
4
Check wiring continuity from the control module to the solenoid B connector; repair any open or damaged wires.
5
If wiring and solenoid are intact, verify the control module is commanding the solenoid by monitoring the output signal during shift lock operation.
Estimated Repair Cost
$150 - $600

The most common cause of P092A (Gear Shift Lock Solenoid/Actuator Control Circuit "B"/Open) is: Broken wire or disconnected connector in the shift lock solenoid circuit B
Typical repair costs for P092A range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Loss of the secondary shift lock circuit reduces the safety margin of the park interlock system. If the primary circuit also fails, the vehicle could be shifted out of Park without proper safety conditions being met.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P092A to identify the root cause.
