What does code poo21 mean?
What the P0021 code means. 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 causes a P0021 code?
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. When trouble code P0021 is set, it means that the intake camshaft in Bank 2 is more advanced than the ECM has told it 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 does p0021 mean in engine ECM?
P0021 Meaning. This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve. The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature.
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 are the symptoms of a p0021 DTC?
A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1. Most likely a P0021 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well.
P0021 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Advanced or System Performance (Bank 2)”.
What is the p0022 code on an intake camshaft?
Code P0022 is logged when the PCM perceives an over-retarded or over delayed timing condition in Bank 2 of the intake camshaft. The crankshaft and camshaft position sensors relay information to the PCM. The module uses the data to determine whether the engine is timed properly by comparing the input from both sensors.
