What is a intake camshaft position timing?

What is a intake camshaft position timing?

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 is the diagnostic code for camshaft position a-timing?

Cost of diagnosing the P0012 code. P0012 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Retarded (Bank 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What happens when the camshaft position sensor fails?

Once your car’s computer detects a CMP sensor failure, it will trigger the engine light and store a diagnostic trouble code (DTC) in its memory (see the table below for common camshaft position sensor trouble diagnostic codes). As you may expect, the specific location of the camshaft position sensor varies by a vehicle’s make and model.

What causes the variable camshaft timing code p0012?

This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing. What causes the P0012 code? The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position.

How to check Bank 1 intake camshaft timing?

Replacing the camshaft oil control valve for bank 1 intake camshaft. Check the timing chain alignment for jumped timing problems and repair as needed. The camshaft phaser controls the timing advance and retard function through oil pressure and oil. The oil needs to be the proper viscosity for the camshaft timing control to work as designed.

What happens when a camshaft position sensor goes bad?

This data is then sent to the powertrain control module (PCM) for use with fuel injector and/or ignition system control. When your camshaft position sensor is faulty or starts having issues, the first thing you should notice is that your “Check Engine” light comes on in your dashboard.

Is a P0011 code bad?

Is Code P0011 Serious? Any time that a vehicle stores an active P0011 trouble code, inefficient engine operation is to be expected. Decreased fuel economy often comes as a result, as does a reduction in power. Vehicle stalling, as well as starting difficulties, can also result.

How do you fix a P0011 code?

What repairs can fix the P0011 code?

1. Resetting the fault codes and performing a road test.
2. Changing the oil and filter to the proper oil viscosity for the engine specifications.
3. Repairing or replacing the wiring to the camshaft oil control valve for bank 1 intake camshaft.

What does the p0011 code on an engine mean?

What the P0011 code means. P0011 is the OBD-II generic code indicating the engine control module (ECM) has determined that the bank 1 intake camshaft is more advanced than what the ECM has commanded it be.

What should I do if I find a p0011 set?

If the initial P0011 sets and other codes are present then erase all codes and do five camshaft drive cycles and then re-investigate which codes come back. If any of these codes are present disregard and erase. If they come back it is electrical wiring or connection failure.

How much does it cost to repair a p0011 Chevy engine?

The cost to diagnose the P0011 CHEVROLET code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

What are the symptoms of a p0011 DTC?

Potential Symptoms. Most likely a P0011 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.
