Code P1920 Description
The P1920 code indicates that there is an issue with the engine mounting control solenoid, specifically an open circuit or short to ground. The engine mounting control solenoid is responsible for controlling the engine mounts, which help dampen engine vibrations and reduce noise. When this solenoid is not functioning properly, it can lead to increased engine vibrations, rough idling, and poor overall vehicle performance. If left unaddressed, this issue can lead to increased wear on engine components and potentially affect the vehicle's drivability.
Common Causes of P1920
- Faulty engine mounting control solenoid
- Wiring issues or damaged wiring harness
- Corrosion or poor connections in the electrical system
- Short circuit in the solenoid
- Faulty engine control module (ECM)
Symptoms of P1920
- Increased engine vibrations
- Rough idling
- Engine misfires
- Reduced fuel efficiency
