Frequently Asked Questions about P3425 2017 Chevrolet Silverado Code
1. What does the OBDII code P3425 mean on a 2017 Chevrolet Silverado?
P3425 indicates an issue with the Cylinder 4 Deactivation Solenoid Valve Control Circuit, which is part of the Active Fuel Management (AFM) system responsible for deactivating cylinders to improve fuel efficiency.
2. What are the symptoms of the P3425 code on a 2017 Chevrolet Silverado?
Common symptoms include reduced engine performance, rough idle, poor fuel economy, illuminated check engine light, and potential misfires.
3. What causes the P3425 code to appear?
The code can be triggered by a faulty cylinder deactivation solenoid, wiring issues like damaged or corroded connectors, low engine oil pressure, or a malfunctioning ECM.
4. Can low oil pressure cause the P3425 code?
Yes, low oil pressure can prevent the deactivation solenoid from functioning properly, as the system relies on adequate oil pressure to operate.
5. How do you diagnose the P3425 code on a 2017 Chevrolet Silverado?
Diagnosis involves using an OBDII scanner to confirm the code, inspecting the solenoid and its wiring for damage, checking oil pressure, and testing the ECM for proper function.
6. How can the P3425 code be fixed?
Repairs may include replacing the cylinder 4 deactivation solenoid, repairing damaged wiring or connectors, changing the oil if degraded, or addressing oil pressure issues.
7. Is it safe to drive with the P3425 code?
Driving with this code may not cause immediate damage, but performance issues and potential engine damage from prolonged operation should be addressed promptly.
8. How much does it cost to fix the P3425 code on a 2017 Chevrolet Silverado?
