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 the a stand for in a p0021 engine?
The “A” camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.
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.
How does the camshaft position actuator work?
The timing issue is typically detected during higher RPMs of the engine when the ECM attempts to adjust valve lift during higher speeds. The ECM uses sensors to detect the position of the crankshaft and camshaft (s). From these sensor signals, the ECM controls ignition, valve lift, and fuel timing under various speeds and loads.
What is the trouble code for camshaft position a?
P0021 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Advanced or System Performance (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
The “A” camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.

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.
