P092D — Gear Shift Lock Solenoid/Actuator Control Circuit “B” High #

Note: The code label may differ depending on the manufacturer. Below are some known variations:

• Gear Shift Lock Solenoid/Actuator Control Circuit “B” High (Generic OBD-II)
• Shift Lock Solenoid Circuit High (B) — Ford
• Shift Lock Actuator Control High Input — Toyota/Lexus
• Gear Selector Lock Circuit B High — Honda/Acura
• Shift Interlock Solenoid High Voltage (B) — GM/Chevrolet

Code P092D Summary #

The P092D diagnostic trouble code (DTC) indicates a problem with the control circuit for the gear shift lock solenoid/actuator, specifically circuit “B”. The shift lock solenoid is an electromechanical component that prevents the shifter from moving out of the “Park” position unless certain conditions are met (such as pressing the brake pedal). When the PCM (Powertrain Control Module) or TCM (Transmission Control Module) detects a high voltage condition in this circuit, it triggers the P092D code. This is typically related to electrical issues—like wiring faults, a failed solenoid, or a problem with the related control module. While this code often affects automatic transmissions, the specific impact can vary by vehicle and manufacturer.

Frequent Symptoms for Code P092D #

If your vehicle has stored a P092D code, you may experience one or more of the following symptoms. Depending on the severity of the fault, these symptoms can range from minor annoyances to significant drivability concerns.

• Shifter stuck in “Park” or will not move out of “Park”
• Transmission warning light or check engine light illuminated
• Brake lights may not come on when pressing the pedal (in some designs)
• Unusual clicking or buzzing noises from the shifter area
• Intermittent ability to shift gears
• In some vehicles, manual shift override may allow temporary shifting

Probable Causes for Code P092D (Most to Least Common) #

The P092D code is usually triggered by an electrical abnormality in the shift lock solenoid’s “B” circuit. Here are the most common causes, listed in order of likelihood based on field experience:

1. Faulty gear shift lock solenoid/actuator (internal short or failure)
2. Damaged, corroded, or shorted wiring/connectors in the circuit
3. Faulty brake pedal switch (prevents proper signal to the solenoid)
4. Blown fuse or relay associated with the shift lock circuit
5. Malfunctioning PCM or TCM (rare, but possible)
6. Aftermarket device interference (alarms, remote starters, etc.)

Step-by-Step Diagnostic for Code P092D #

Diagnosing P092D requires a methodical approach to eliminate guesswork. Here’s how a professional technician would typically proceed:

• Verify the code with a scan tool and check for related DTCs.
• Inspect shift lock solenoid/actuator for physical damage or corrosion.
• Check wiring and connectors from the solenoid to the control module for signs of fraying, corrosion, or shorts to power.
• Test the solenoid resistance with a digital multimeter; compare the reading to manufacturer specs.
• Activate the solenoid using a scan tool’s output control function (if available) to confirm operation.
• Test the brake pedal switch for continuity and proper operation (since it’s involved in shift interlock logic).
• Inspect and test related fuses/relays for the circuit.
• If all else checks out, consider PCM/TCM issues or aftermarket device interference.

Possible Repairs for Code P092D #

Once you’ve identified the root cause, repairing P092D typically involves one or more of the following actions:

• Replace the faulty shift lock solenoid/actuator
• Repair or replace damaged wiring or connectors
• Replace the brake pedal switch if it’s not providing the correct signal
• Replace blown fuses or faulty relays associated with the circuit
• Reprogram or replace the PCM/TCM (only after all other causes are ruled out)
• Remove or properly integrate aftermarket electronics that may be interfering

Is It Safe to Drive with P092D? #

Generally, it is NOT recommended to drive with a P092D code if your shifter is stuck or intermittently stuck in “Park.” In some cases, you may be able to use a manual override to shift out of “Park” temporarily, but this is not a permanent fix and could leave you stranded if the override fails. If the vehicle shifts normally and you see only the warning light, driving may be possible for a short distance—to a repair shop, for example—but the issue should be addressed as soon as possible to prevent being immobilized.

Vehicles Most Commonly Affected by P092D #

While P092D can appear on a range of vehicles with electronically-controlled shifters, it is more prevalent on certain models—especially those with advanced shift interlock systems. Based on field data, these brands and models see this code most often:

• Ford (Focus, Fusion, Escape, Explorer)
• Toyota (Camry, Corolla, RAV4)
• Honda/Acura (Accord, Civic, CR-V, MDX)
• GM/Chevrolet (Malibu, Impala, Silverado, Equinox)
• Dodge/Chrysler (Charger, Grand Caravan, Pacifica)
• Hyundai/Kia (Sonata, Elantra, Sorento)

This is not an exhaustive list; any vehicle equipped with an electronically-controlled shift lock can potentially trigger P092D.

Common Mistakes & Best Practices for Code P092D #

When troubleshooting P092D, even seasoned technicians can fall into certain traps. Here’s what to watch for, and how to get it right:

• Overlooking simple wiring issues. Many problems are caused by corroded or damaged connectors—always check these first.
• Replacing the solenoid without testing it. A quick resistance check can save time and money.
• Ignoring related codes. Other DTCs may point to root causes (like brake light or transmission range sensor faults).
• Not checking for blown fuses or relays. These are quick to verify and often overlooked.
• Forgetting about aftermarket devices. Remote starters and alarms can interfere with shift interlock circuits.

Express FAQ for P092D #

Got quick questions about P092D? Here are some fast answers:

• Q: Can I clear the code and keep driving?
  A: You can clear the code, but if the fault remains, it will return. Address the root cause to avoid being stuck in “Park.”
• Q: Will replacing the shift lock solenoid always fix it?
  A: Not always—sometimes the problem lies in the wiring, the brake switch, or related modules. Always diagnose before replacing parts.

If you’re not comfortable working with vehicle electrical systems, it’s wise to consult a professional technician or your OEM dealer for a thorough diagnosis and safe repair.
