Introduction
Error code P092C is an OBD-II code that indicates a problem with the shift lock solenoid or actuator “B” control circuit. This issue is typically caused by a detected low voltage in the circuit, which can prevent smooth gear shifting.
Possible Causes
Several factors can cause the P092C code:
- Faulty shift lock solenoid or actuator
- Damaged or short-circuited wiring harness
- Corroded or improperly connected connector
- Problem with the Transmission Control Module (TCM)
Symptoms
Symptoms associated with code P092C include:
- Difficulty shifting into certain gears
- Irregular or delayed gear shifting
- Illumination of the check engine light
- Activation of limp mode preventing certain gear shifts
Diagnosis and Repair
- Visual Inspection: Check connectors and wiring for any damage or improper connections.
- Solenoid/Actuator Testing: Use a multimeter to measure the component’s voltage and resistance to verify proper operation.
- Electrical Circuit Check: Verify the solenoid’s supply voltage and look for any electrical anomalies.
- Replacement of Faulty Components: If the solenoid, wiring harness, or control module is defective, replace it according to manufacturer recommendations.
Conclusion
Codes P2009 and P092C indicate problems affecting engine and transmission performance. Thorough inspection and accurate diagnosis help identify and resolve these issues to ensure proper vehicle operation.
