What does P0011 Chevy Silverado mean? This error code means your camshaft and camshaft solenoid is not operating properly. Which Chevy model you own doesn’t matter, the reasons for these codes are almost the same.
However, camshaft position failure is not the only cause of this code. There are some other reasons for the P0011 code. Let’s check out the reason, symptoms, and solution in detail.
Code P0011 Chevy Silverado: Reason and Symptoms
P0011 technical definition in the Chevy is-
“Intake valve timing control performance bank 1”
Here, P stands for Powertrain of the car engine. 0 and 1 stands for air-fuel mix and 11 stands for camshaft position.
A quick view of the reason and the symptom of P0011 in the table-
|Engine oil quality and low oil pressure
|The engine hardly starts and makes a rattling noise
|Actuator passage got blocked
|Rough drive or jerks while running
|Camshaft Position problem
|Limiting fuel mileage
|Faulty oil control valve
|The engine light gets on
|Failed in emission test
2012 Chevy Silverado code P0011 indicates mostly that the camshaft placement is not in the desired place; it becomes too advanced. When the Engine Control Module (ECM) cannot correct the camshafts position angle, the car cannot burn fuel efficiently.
1. Engine oil quality and low oil pressure
This is one of the main reasons for code P0011 Chevy Silverado 6.0. If the oil pressure is not enough the camshaft position actuators’ performance affects. The causes of low oil pressure are-
- Dirty oil
- Usage of wrong viscosity oil
- Faulty oil pump
- Damaged oil filter
Solution: Dirty oil damages the car engine and reduces its mileage. Engine oil needs replacing after 3000 miles of driving or every three months. If you haven’t changed the oil for a long time, your engine oil will get dirty.
So, the first solution for the P0011 error code is to flush out the oil from the engine and replace it with the manufacturer’s special engine oil. The oil filter also needs replacement. Check the amount of the oil also.
2. Actuator passage got blocked
Blocked actuator passage creates 2014 Chevy Silverado 4.3 P0011 error code. It decreases engine performance.
Solution: Dirty oil is the reason for this problem. So, the replacement of old and degraded oil will fix the problem.
3. Camshaft Position problem
ECM commands to camshaft and camshaft sensors to have an advanced position. But sometimes, the camshaft got a more advanced position, and error P0011 Chevy Silverado 2007 occurred.
ECM always couldn’t fix or detect the actual camshaft position, and that means the camshaft is not at the right angle or an advanced position.
The maneuver of the camshaft should be perfectly timed for a perfect air-fuel mixer when the engine requires it.
Solution: First, check all the wires of ECM to the camshaft carefully. Diagnosis of camshaft sensor wiring will solve the problem.
4. Faulty oil control valve
The ECM runs the oil control solenoid electrically. This solenoid supplies engine oil to the car’s actuator. And this actuator modifies the camshaft position by adjusting valve timing.
So, if the oil control solenoid is faulty or clogged, the actuator can work properly. It is the reason mostly for the 2007 Chevy Silverado 6.0 P0011.
Solution: First, check all the wires that are connected to the bank 1 oil control valve. If any broken wire is found, repair it and have a test drive. If there is no wiring issue, replace the camshaft oil control valve for the bank 1 intake camshaft.
5. Overflow of oil
If there is continuous oil flow to the camshaft timing chamber 2010 Chevy Silverado 5.3 P0011 shows.
Solution: This problem indicates the timing chamber is faulty. So, you need to check the timing chain, which may need replacement. You need to visit the dealer’s office for this.
