What it means
The gear shift lock solenoid/actuator control circuit B reports a control circuit b high condition. Selector lever interlock cannot be commanded reliably.
At a glance
- Usually lights the check-engine light
How it works
Circuit B controls the gear-shift lock solenoid or actuator that helps keep the selector in Park until release conditions are met. P092D sets when the module detects circuit B voltage higher than expected, which can result from a short to battery voltage or an open actuator coil.
Common causes
Most likely first.
- Control wire shorted to B+
- Open coil
Symptoms
- Selector may not shift out of Park
- Shift-lock warning or check-engine light may illuminate
How to diagnose it
- Record freeze-frame data and scan for related interlock codes to establish when the circuit B fault was detected.
- Check whether the selector releases from Park and whether the code returns while pressing the brake and operating the selector.
- Inspect circuit B wiring for contact with a power feed, damaged insulation, loose connectors, or backed-out terminals.
- Use a scan tool to observe circuit B status while commanding the actuator, if supported.
- Test circuit B for a short to battery voltage and check the actuator coil for an open, using the manufacturer's specification.
- If static checks pass, move the harness while monitoring the circuit to find an intermittent short or open.
Common fixes
- Repair circuit B wiring shorted to a power feed.
- Restore a loose or damaged circuit B connector connection.
- Replace the circuit B actuator if its coil is open.
Can I keep driving?
If the selector cannot be moved or secured reliably, do not drive the vehicle. If it operates normally, keep trips short and stop if the interlock or shifting becomes unreliable.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
