See Also: Diagnostic Trouble Code P0008, P0010, P0012, P0021 Symptoms of Code P0011 When a vehicle’s PCM detects that the engine’s valve timing is not reflective of proper camshaft actuation, a P0011 DTC is stored. Solenoid related issues of any type can result in a failure to adjust cam timing. The bulk of today’s engines rely upon a specialized solenoid to direct oil flow through the systems cam phasing module. As a result, engine power is enhanced, while emissions output is reduced. This process is achieved through the use of cam phasing technology, which modifies the angular position of an engine’s camshaft, to its crankshaft. As a result, vale timing is allowed to mirror piston movement within each respective cylinder at a more consistent rate.

YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Engine timing issues require special tools that allow the mechanic to test the engine timing as well as reset the timing correctly when all of the repairs are completed. Wiring/connector replacement to or from the camshaft adjustment valveĪdditional comments for consideration regarding the P000A codeĭue to the variety of issues that could be causing your vehicle to store this code, the most efficient and timely way to solve the problem is to take it to a professional.Clearing of the oil pump pickup tube filter and other oil passages.Repairs that may eliminate this stored code include: However if the issue isn’t addressed in a timely manner, serious damage may occur to parts such as the camshaft follower, requiring even more expensive repairs down the road. The vehicle may appear to run smoothly, with no apparent major problems. If any of the oil pump connections become degraded or passageways become clogged, the reduced oil pressure may trigger a camshaft position slow response code. While the problem may lie with the actual camshaft mechanism or surrounding components, poor oil pressure is often overlooked as a cause of this code. Inspection of the oil pump pickup tube filter and other oil passagesĬommon mistakes when diagnosing the P000A code.Output test on the camshaft adjustment valve (N205).Inspection of the camshaft adjustment mechanism.Visual inspection of wiring and connectors.Other steps that may be required include: The codes will then be cleared and the vehicle retested to see if the same fault returns. Your technician will likely begin the diagnostic procedure by verifying the code and addressing any codes that set previously to P000A. How does a mechanic diagnose the P000A code? Sometimes other codes in the P000 series will present. Oftentimes the only symptom of this problem will be an illuminated Check Engine light. Damaged or corroded connector terminal, wiring, or harness. A faulty VCT (variable cam timing) phaser.A faulty camshaft position actuator solenoid.Low oil pressure due to restriction in an oil passage or a bad oil pump.What causes the P000A code?ĭue to the large number of moving parts involved in the engine and cam system, there’s a wide range of possibilities that may cause this code: If the change in the camshaft’s position is smaller than it should be during a specific time period, called the diagnostic time, the PCM detects this deficit and over time, if these changes in response time continue, the P000A will set. The PCM (powertrain control module) monitors the camshaft’s position as well as where its future position is supposed to be. “A” indicates that the problem involves the intake valves on Bank 1. When your vehicle sets code P000A, it means the timing of this process is slower than expected by the vehicle’s computer. The timing of this process is critical to the engine running efficiently and correctly. The purpose of camshafts in a vehicle is to open and close the intake and exhaust valves on the engine’s cylinders in order to keep the engine running smoothly. You may also see a 00010 fault along with this code, which indicates that the problem is in Bank 1. This code is known as ‘A’ Camshaft Position Slow Response Bank 1.
