Code P3452 2016 GMC Sierra Description
The P3452 diagnostic trouble code (DTC) for a 2016 GMC Sierra relates to the Cylinder 7 Deactivation Solenoid Valve Control Circuit High Voltage. This code indicates that there is a high voltage condition detected in the control circuit for the solenoid valve that is responsible for deactivating cylinder 7 in the engine. In vehicles equipped with cylinder deactivation technology, certain cylinders can be shut down under light load conditions to improve fuel efficiency. The solenoid valve controls the oil flow to the lifters, which in turn control the movement of the valves in the deactivated cylinder.
Common Causes of P3452 2016 GMC Sierra
- Short circuit in the control circuit
- Open circuit in the control circuit
- Malfunctioning solenoid valve
- Faulty engine control module (ECM)
- Wiring issues or corrosion in the circuit
Symptoms of P3452 2016 GMC Sierra
- Rough engine idle
- Engine misfires
- Reduced power output
- Check Engine Light illuminated
- Vehicle going into limp mode
How to Fix P3452 2016 GMC Sierra
- Begin by performing a visual inspection of the wiring and connectors related to the solenoid valve control circuit.
- Use a multimeter to test the continuity of the wiring and check for any shorts or opens in the circuit.
- Test the solenoid valve itself to ensure it is functioning properly.
- If the solenoid valve and wiring are in good condition, then the issue may lie with the ECM, which may need to be reprogrammed or replaced.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P3452 2016 GMC Sierra
The typical repair costs for addressing the P3452 code on a 2016 GMC Sierra can vary depending on the exact cause of the issue. In general, the cost of parts for a solenoid valve replacement can range from $100 to $200, while the cost of labor can be between $100 and $200. Therefore, the total cost for this repair could range from $200 to $400. It is important to note that these costs are just estimates and can vary based on factors such as location, the specific diagnosis time, and labor rates at auto repair shops.

Frequently Asked Questions about P3452 2016 GMC Sierra Code
1. What does the OBDII code P3452 mean on a 2016 GMC Sierra?
P3452 indicates a high voltage issue in the Cylinder 7 Deactivation Solenoid Valve Control Circuit, which is part of the Active Fuel Management (AFM) system.
2. What are the common symptoms of the P3452 code in a 2016 GMC Sierra?
Symptoms may include reduced engine performance, poor fuel economy, a check engine light, and possible rough idling or misfires.
3. What causes the P3452 code in a 2016 GMC Sierra?
Common causes include a faulty cylinder deactivation solenoid, damaged wiring or connectors, a malfunctioning PCM (Powertrain Control Module), or low oil pressure.
4. Can low oil pressure trigger the P3452 OBDII code?
Yes, low oil pressure can affect the operation of the AFM system, including the Cylinder 7 Deactivation Solenoid, causing this code.
5. How can I diagnose the P3452 code on my 2016 GMC Sierra?
Start by inspecting the wiring and connectors for damage, checking the solenoid’s resistance, and verifying oil pressure. Use a scan tool to monitor AFM operation and confirm the fault.
6. Is it safe to drive a 2016 GMC Sierra with the P3452 code?
Driving with this code is not recommended, as it may lead to engine damage, reduced performance, and higher fuel consumption.
7. How do I fix the P3452 code on a 2016 GMC Sierra?
Repairs may include replacing the Cylinder 7 Deactivation Solenoid, repairing or replacing damaged wiring, or updating/reprogramming the PCM if necessary.
8. How much does it cost to repair the P3452 code in a 2016 GMC Sierra?
Repair costs vary but typically range from $150 to $500, depending on whether the solenoid, wiring, or PCM needs repair or replacement.
9. Can a bad PCM cause the P3452 code on a 2016 GMC Sierra?
Yes, a malfunctioning PCM could fail to regulate the Cylinder 7 Deactivation Solenoid, triggering the P3452 code.
10. How do I prevent the P3452 code from recurring in my 2016 GMC Sierra?
Regular maintenance, including oil changes with the correct viscosity, inspecting wiring for damage, and addressing AFM system issues promptly, can help prevent this code.
