Frequently Asked Questions about P3442 2017 GMC Sierra Code
1. What does the OBDII code P3442 mean on a 2017 GMC Sierra?
The P3442 code indicates an issue with the Cylinder 6 Deactivation Solenoid Valve Control, which is part of the Active Fuel Management (AFM) system.
2. What are the common symptoms of a P3442 code?
Symptoms may include a check engine light, reduced engine performance, rough idling, misfires, and decreased fuel efficiency.
3. What causes the P3442 code to appear?
Common causes include a faulty deactivation solenoid, clogged oil passages, low oil pressure, electrical connection issues, or a malfunctioning Powertrain Control Module (PCM).
4. Can low oil pressure trigger the P3442 code?
Yes, low oil pressure can prevent proper operation of the AFM system, leading to a P3442 code.
5. How do I diagnose a P3442 code on my 2017 GMC Sierra?
Diagnosis involves checking the solenoid valve, inspecting oil levels and pressure, testing electrical connections, and using a scan tool to monitor AFM system performance.
6. Is it safe to drive with a P3442 code?
Driving is possible but not recommended, as it can lead to engine performance issues and potential long-term damage if left unresolved.
7. How do I fix the P3442 code?
Repair may include replacing the Cylinder 6 deactivation solenoid, cleaning or repairing oil passages, fixing wiring issues, or updating/replacing the PCM if necessary.
8. Can dirty or degraded oil cause the P3442 code?
Yes, dirty or degraded oil can restrict the solenoid’s operation and trigger the code. Regular oil changes are crucial for AFM system performance.
9. What tools are needed to address the P3442 code?
You’ll need a scan tool, multimeter, oil pressure gauge, and basic mechanical tools to diagnose and repair the issue.
10. How much does it cost to repair a P3442 code on a GMC Sierra?
Repairs can range from $100 to $1,000 depending on the cause, such as replacing a solenoid or addressing more complex engine issues.
