OBD II Codes (P0000 - P0099) | P0011 “Intake Camshaft Position Timing - Over-Advanced (Bank 1)”

Meaning:

Fault code p0011 means “A” camshaft position timing- over advanced (bank) This code pertains only to vehicles with variable valve timing.
Within these systems, an actuator rotates the engine camshaft to advance or retard camshaft timing.
This effectively manipulates when an engine's valves open and close in relation to when each cylinder reaches the top dead center.
The cam phasing associated with variable valve timing facilitates this process, and assists in maximizing performance, while minimizing emissions.
In most engines, a solenoid is used to direct oil flow during the cam phasing process.
An issue with this solenoid can result in incorrect variable camshaft timing. In the case of fault code p0011, the cam is advanced of where it should be in relation to system demands.

causes:

Many different problems can trigger code P0011. Some of the common issues include:

• Engine oil is dirty
• Engine oil is too low
• Engine oil is incorrect viscosity
• Issues with the PCM, such as software in need of an update
• Camshaft variable valve timing control solenoid failure
• Circuit issues (e.g., damaged wiring, loose connections)
• Camshaft phaser is seized in the advanced position
• Continuous oil flow to Variable Camshaft Timing chamber

Symptoms:

If your vehicle is experiencing error code P011, you may observe one or more of the following symptoms:

• Check Engine Light
• Stalling
• Poor idling
• Hard starting the engine
• Poor fuel economy
• Engine misfire
• Failed emission test
• Rattling noise from the engine

The P0011 fault code may cause your vehicle to have:

Effect caused:

• The engine may run erratic and stall, hesitate, run rough, or have a hard-starting condition.
• The engine may have excessive fuel consumption, carbon fouling of engine components, and various drive complaints depending on the camshaft failed position.
• Driving the vehicle for prolonged time with the camshafts not advancing or retarding may cause other problems to the valve train or engine depending on the cause of the failure.

Diagnosis:

Solution:

• Step 1: Check and Change Oil
The most common fix for a p0011 fault code is to change an engine’s oil and oil filter. Doing so will solve the bulk of p0011 DTC issues, as oil starvation will prevent proper actuation of cam timing.
• Step 2: Fix Any Wiring Damage
If any wiring issues are discovered, repairs will be needed. This might include splicing or soldering of damaged wires, or the replacement of connectors that have been broken or do not clasp tightly to their corresponding connector within the circuit.
• Step 3: Replace Oil Control Valve
If model-specific testing reveals a defective oil control valve, the replacement will be necessary. Doing so can be somewhat of an extensive repair, often involving the removal of an engine’s valve cover or timing cover. Before taking on such a repair, be sure to have a service manual on hand for reference.
