What does the OBD 2 error code p0021 mean?
Error Code P0021 means that the OBD II system has found a problem in the PCM’s (Powertrain Control Module) Variable Valve Timing (VVT) or Variable Camshaft Timing (VCT). This code shows up when the camshaft is not in the position commanded, and advanced of where it’s supposed to be.
What is the diagnostic code for camshaft position a?
P0021 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Advanced or System Performance (Bank 2)”.
What is the OBD code for bank 2?
P0021 is the OBD-II generic code indicating that the Engine Control Module (ECM) has determined that the bank 2 intake camshaft is more advanced than what the ECM has commanded it to be. This over advanced condition could be during advancing, or retarding of the camshaft timing.
What is the error code for bank 2?
Error Code P0021: A Camshaft Position – Timing Over-Advanced or System Performance (Bank 2) Error Code P0021 is defined as A Camshaft Timing Overbalanced, Bank 2. Generally, this refers to over advanced timing or system performance trouble on Bank 2.
What can cause a p0021 DTC trouble code?
A P0021 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 Failed timing valve control solenoid (stuck open)
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.
P0021 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Advanced or System Performance (Bank 2)”.
What does DTC code p0011 ” a ” stand for?
Wiring problems (harness/wiring) in intake timing control valve control solenoid system Continuous oil flow to VCT piston chamber Failed timing valve control solenoid (stuck open) This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis.
