What causes the p0021 OBD-II trouble code?
What causes the p0021 OBD-II trouble code?
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 the P0021 code?
What does the p0012 code on an engine mean?
What the P0012 code means. P0012 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake camshaft timing for bank 1 is more retarded than what the ECM has commanded it be.
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 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 the P0012 code means. P0012 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake camshaft timing for bank 1 is more retarded than what the ECM has commanded it be.
What do the p0011 and p0021 codes mean?
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 to do if your check engine light says p0022?
Check to see if there are any other codes along with P0022 and clear your Check Engine Light with FIXD. Check the engine oil level and condition. If it’s low, adjust to spec and test drive to see if the concern is resolved. If it’s dirty, change the oil and filter and test drive to see if the concern is resolved.
What does a p0010 code mean on an OCV?
When you consider what these codes are saying, it becomes obvious that these codes are more indicative of a mechanical failure or the results of poor maintenance. These four DTCs could be an electrically failed OCV but they would most likely be accompanied by a P0010 or P0020 code.
