What does DTC p0011 and p0021 stand for?
These four DTCs could be an electrically failed OCV but they would most likely be accompanied by a P0010 or P0020 code. For the P0011 and P0021 codes to appear indicates that the OCV solenoid is mechanically open at all times and allowing engine oil to move the intake camshaft (s) without PCM intervention.
What does the p0011 code on a camshaft mean?
Different manufacturers have slightly different criteria for when this code is set, but a P0011 code points to an Advanced Camshaft Timing condition that won’t respond to PCM commands.
What does p0011 stand for in VVT?
The way VVT works is that the ECM/PCM closely monitors the cam/crank timing and uses an oil control solenoid to manipulate the relationship between the cam gear (s) and the camshaft (s) according to predetermined algorithms. Again, the P0011 DTC stands for “A” Camshaft Position Timing Over Advanced or System Performance Bank 1.
What do the p0012 and p0022 codes mean?
For the P0012 and P0022 codes to appear indicates that the OCV solenoid is mechanically closed at all times and not allowing engine oil to move the intake camshaft (s) when commanded (ground applied) by the PCM.
What does p0011 mean on a camshaft?
Bank one is the bank of cylinders that contains cylinder one. This code indicated that the camshaft timing is above the threshold, also called being over-advanced. What Are the Symptoms of Code P0011? Like other timing issues, an over-advanced camshaft can cause the engine to run rough.
What does code p0021 mean on the ECM?
What Does Code P0021 Mean? The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft (s) is (are) adjusted by the ECM through the use of an oil control valve (s) (OCV) also called variable valve timing control solenoid valves.
What causes a p0011 DTC trouble code to be set?
Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates. A P0011 DTC trouble code may be caused by one or more of the following: Incorrect camshaft timing Wiring problems (harness/wiring) in intake timing control valve control solenoid system Continuous oil flow to VCT piston chamber
What does p0011 stand for in Bank One?
For example, VVT changes the fuel-air mixture in the engine by opening the cylinder valves for variable amounts of time. This can result in more fuel efficiency or more power as needed. While problems with these systems can set several different codes, P0011 refers to the “A” camshaft in bank one.
