This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car has detected a problem with the circuit that controls the exhaust valve for cylinder number 2. It's like a light switch that isn't working properly, causing the valve to not open or close as it should.
The engine control module (ECM) monitors the exhaust valve control circuit for each cylinder. If the voltage in the circuit for cylinder 2 is higher than expected, it triggers this code.
P3416 indicates that the ECM has detected a high voltage condition in the exhaust valve control circuit for cylinder 2. This can be due to an electrical fault such as a short to power, or a malfunction in the control solenoid or wiring.
• Check Engine Light is on
• Reduced engine performance
• Possible misfire or rough running
• Faulty exhaust valve control solenoid
• Short to power in the control circuit
• Damaged wiring or connectors
ECM: Engine Control Module
Solenoid: A coil of wire acting as a magnet when carrying electric current, used in various automotive applications.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the exhaust valve control solenoid for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty exhaust valve control solenoid.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly inspect and maintain engine wiring.
• Ensure timely servicing of engine components.
• Avoid harsh driving conditions that may stress engine parts.
Engine Performance
• Have the vehicle diagnosed and repaired by a professional.
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
Check with the vehicle manufacturer for warranty coverage on engine control components.
This code has been associated with issues in vehicles with variable valve timing systems, particularly in GM models.
Moderate – It should be addressed soon to avoid potential engine damage.
Driving with a malfunctioning engine can lead to increased emissions and potential safety risks.
• Engine at operating temperature
• Vehicle in a safe location for testing
The exhaust valve control solenoid is typically located near the cylinder head on the engine.
Q: Can I drive with a P3416 code?
A: It's not recommended to drive with this code active, as it can lead to further engine damage.
Q: What happens if I ignore the P3416 code?
A: Ignoring the code can result in poor engine performance and potentially more costly repairs.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
