Did you read the codes on your car’s computer using an OBD-II scanner, and it reads “Camshaft Position Timing Over Advanced Bank 1 – P0011 code” on display? Here’s all you need to know.
One generic OBD-II code standard with car manufacturers is the P0011 code. Generic mean that it’s shared across car manufacturers, but vehicles using the variable camshaft Timing is more likely to be affected by this trouble.
The P0011 code is standard among car brands such as Nissan, Subaru, Chevrolet, GMC, and Hyundai.
The P0011 code, which stands for “Bank 1” Camshaft Position Timing Over Advanced, indicates that the PCM cannot correct a noticeable slight difference in the actual position angle of the camshaft and the desired position angle.
Please continue reading to know everything about the P0011 error code, including its meaning, causes, symptoms, diagnosis, and fixing.
What is a camshaft position timing over advanced bank 1?
The Camshaft Position Timing Over Bank 1, also referred to as the P0011 code, indicates that the Engine Control Module (ECM)/Powertrain Control Module(PCM) has identified a disparity between the intended angle of the camshaft position and its actual position which has been unable to rectify.
Essentially, the computer is trying to achieve a specific target angle for the camshaft, but the sensors indicate that it is impossible.
Regarding the Bank 1 or “A” reference, it usually denotes that the intake camshaft is in an inline overhead camshaft engine. Similarly, in an engine with a V configuration, the “A” often indicates the intake camshaft on Bank 1.
