![]() If factory testing has revealed the presence of a defective oil control valve, replacement must be made. Step 6 – Replace Oil Control Valve (If Necessary) Therefore, factory service literature should be consulted. The exact protocol for verifying the integrity of these components differs by manufacturer. However, no such component should be condemned until further diagnostics are completed. If no wiring defects are noted, an engine’s cam phasers or hydraulic control valve become suspect. If any such defects are found, repair will be necessary. All wiring should be carefully inspected for the presence of fraying, breakage, and pinched spots. If fault code P0011 returns, attention should be placed upon wiring related to the Bank 1 oil control solenoid. If the code reappears, further diagnostics will be necessary. If P0011 does not return, you have likely corrected the issue at hand. This will be followed by a moderate length test drive to ensure that the offending code does not return. With your vehicle’s oil changed, you should now clear code P0011 from your vehicle’s PCM using your scan tool. Be sure that your engine’s oil is topped off to capacity, and that the proper viscosity of the oil is chosen.Īs many as 75% of P0011 DTCs are remedied with a simple oil change. The first step that should be taken when attempting to diagnose a P0011 trouble code, is to change your vehicle’s engine oil and oil filter. It might be necessary to consult factory service literature in order to determine which code takes precedence. If additional codes are active or stored, it is imperative to consider what role they might play in the onset of code P0011.

This leads to a level of decreased reliability, which some might find problematic. Vehicle stalling, as well as starting difficulties, can also result. Decreased fuel economy often comes as a result, as does a reduction in power. Is Code P0011 Serious?Īny time that a vehicle stores an active P0011 trouble code, inefficient engine operation is to be expected. When either of these issues are suspected, removal and inspection of the system’s oil control solenoid are often necessary. Both of these issues can result in an inability to properly phase the affected engine’s camshaft. The vehicle in question is then taken for a test drive, in a bid to verify that its prior P0011 code does not return.Īdditional P0011-related issues include clogging of the oil solenoid’s integrated screen and system electrical issues. ![]() Therefore, oil-related issues of any type can quickly trigger a P0011 trouble code.Ĭam phasing issues related to engine oil inefficiencies are so common, that standard repair procedure entails changing the affected vehicle’s oil, and clearing the associated code. This stems from the fact that engine oil is used as the driving input force for cam phasing operation. However, few are as prevalent as low engine oil, or the use of oil of an incorrect viscosity. Numerous factors can play a role in the onset of a P0011 code. The following are a number of the most common symptoms associated with the onset of a P0011 trouble code. 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. "A" Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)įault code P0011 is specific to vehicles that utilize variable valve timing in a bid to increase engine operating efficiency.Įngines featuring variable valve timing make subtle timing adjustments on the fly, which effectively vary the point at which each cylinder’s intake/exhaust valves actuate. ![]()
