The P16CF fault code refers to an issue with the control circuit of the intake rocker arm solenoid valve 2. This valve is responsible for controlling the oil flow to the rocker arm, which in turn changes the camshaft lift and duration while the engine is running. The rocker arm actuator system consists of three lobes on the camshaft for each intake valve. The inner lobe is for low lift, while the two outer lobes are for high lift.

In default mode, a locking pin locks the inner and outer mechanisms of the rocker arm together to provide high lift.

However, when low lift is commanded, oil pressure retracts a locking pin within the rocker arm. To control the rocker arm solenoid valve, the Engine Control Module (ECM) sends a 12 V PWM signal. The ECM also supplies a ground to the low reference circuit. If there is a problem with the control circuit of the intake rocker arm solenoid valve 2, the P16CF fault code will be triggered. It is important to address this fault code promptly to ensure proper functioning of the rocker arm actuator system and optimize engine performance.

What are the possible causes of the automobile fault code P16CF?

If you see the engine light or service engine soon warning light on, it could be due to the fault code P16CF. This code is often caused by a faulty intake rocker arm solenoid valve 2, an open or shorted harness for the valve, or a poor electrical connection in the valve circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors related to the Intake Rocker Arm Solenoid Valve 2?

If you’re dealing with an illuminated Engine Light or Service Engine Soon Warning Light, the culprit could be a faulty Intake Rocker Arm Solenoid Valve 2. To visually inspect the wiring harness and connectors associated with this valve, follow these steps. First, check for any open or shorted circuits in the harness. Next, examine the electrical connections for any signs of poor connection. Look out for damaged components and inspect the connector’s pins for any signs of breakage, bending, pushing out, or corrosion. This thorough inspection will help identify any issues and guide you towards the necessary fix.

What should I look for when checking the connector’s pins for the P16CF fault code?

When checking the connector’s pins for the P16CF fault code, you should visually inspect the related wiring harness and connectors.
