What does engine code P0021 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 does the p0021 Nissan engine code mean?
Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code. What does this mean? The cost of diagnosing the P0021 NISSAN code is 1.0 hour of labor.
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 happens when a p0021 DTC is set?
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. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
What are the symptoms of Nissan Altima p0021?
When the timing is too far advanced, it can really cause some issues with the motor. Here are some of the typical symptoms of P0021 in the Nissan Altima: Poor Idle Quality – If the camshaft actuator fails while giving the engine aggressive valve timing, it’ll idle roughly.

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.
What to do if Nissan engine code comes back?
Before replacing the valve, change the engine oil and filter and reset the engine code. If the code comes back you can remove the Intake valve timing control solenoid and clean it with brake cleaner. The cost to diagnose the P0021 NISSAN code is 1.0 hour of labor.
