P3488 Chrysler Code - Cylinder 11 Exhaust Valve Control Circuit High
Quick Answer
When the diagnostic trouble code P3488 appears on a Chrysler vehicle, it indicates an issue with the Cylinder 11 Exhaust Valve Control Circuit being too high. Common causes include Faulty Wiring: Damaged or corroded wiring in the exhaust valve control circuit can cause a high voltage reading, Defective Exhaust Valve Control Solenoid: A malfunctioning solenoid can disrupt the operation of the exhaust valve, leading to high voltage in the circuit, Malfunctioning PCM: A faulty Powertrain Control Module can send incorrect signals to the exhaust valve control circuit, causing voltage issues. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
