The P0011 code - Definition, Causes, and Symptoms (& How to Fix It)

Nobody wants to see the Check Engine Light. You need to learn how to fix a P0011 error code if you scan your system.

We will discuss what the P0011 troublecode means in this guide. This guide also discusses the symptoms, causes, and repair options. 

Definition of code P0011

Camshaft Position “A” – Timing Over-Advanced or System Performance (Bank 1)

What does the P0011 code mean?

P0011 refers to a general powertrain code that can be applied to almost all cars. The engine control module, or ECM, noticed that bank 1's intake camshaft moved beyond what was expected. The P0011 code can be used to refer to Nissan cars.  

The “A” camshaft can be the intake camshaft on the front or left of the bank from the driver. It includes cylinder 1. The camshaft timing could cause this over-advanced condition.

P0011 Trouble code symptoms

P0011 Trouble code is most commonly what causes the Check Engine Light (check engine light) to go on. This code can also cause engine performance issues. But, other signs and symptoms could also occur.

The following symptoms are most commonly seen:

The P0011 code: Causes

Most of the P0011 codes are caused by wiring or camshaft problems with the vital component. 

• The intake timing control system has a defective wiring
• Stuck open timing valve control solenoid
• Faulty camshaft actuator
• Failing timing chain or timing belt can cause incorrect timing of the camshaft.
• Efficient VVT solenoid
• Engine oil low
• Petroleum contaminated with oil
• PCM requires update

What is the P0011 code?

Hohe – When the engine faces an active trouble code, you should always take it seriously. The problem might not immediately be problematic. 

This being said, your car might stall or start to run rough at any given time. The car might not start at all, which can leave you in a bind.

It is important to have any faults with the timing belt or chain quickly fixed. If you're not careful, a damaged timing belt or chain could cause engine damage.

Which Repairs can Fix the P0011 code?

There are many repairs that can fix the P0011 code depending on the problem. A comprehensive diagnostic assessment is the most effective way to determine which solution will work best. 

Below are some suggestions that could help.

• Change camshaft oil control valve
• Replacing the wiring for camshaft oil control valve
• Replace camshaft actuator
• Oil change
• Check and Replace Timing Belt or Chain

Common mistakes in diagnosing P0011

It’s tempting to overlook simple problems that are easy to fix. Everybody tends thinks the worst whenever the Check Engine Light goes on.

However, you don’t want to overlook the value of checking the simple problems first, even if these aren’t the most common causes. It's better to save money than regret it in the long-term. 

Diagnostic Tools

How to diagnose P0011 Trouble code

Professional mechanics will be able to help you pinpoint the root cause of your P0011 code. The following steps would be taken at a reliable workshop.

1. Examine all trouble codes. If there are other codes present, it might indicate what’s wrong with the system. You can clear all codes, then take your car out for a spin until you get new codes. 
2. Make sure to check the oil regularly and make any necessary changes. Check that the oil level has been checked. If it’s time for an oil change, now is the time to do it. There’s always the chance that it will resolve the problem and this is an easy fix. You must use oil with the correct viscosity.
3. Once you have completed the oil change and are ready to go, start the engine again. This is great news if the codes have disappeared. Otherwise, continue with the diagnostic procedures. 
4. Look for wiring defects. Make sure you follow the wires to the Bank 1 control solenoid. You must repair any damage, pinching, or fraying. 
5. Do extensive testing. Check the hydraulic control valve and cam phasers. You can find the steps in your service manual. Sometimes, you may need professional assistance. 

The estimated cost of repair

There are many options for repairing the P0011 error code. These are the estimated costs depending on what you find. 

• Replace camshaft oil control valve – $200-$450
• Replace wiring to camshaft oil control valve – $50-$500
• Replace camshaft actuator – $250-$800
• Replace timing belt or timing belt – $500 – $4000
• Change oil – $15-$150

The P0011 Code: Mechanics Tips

Don’t overlook the chances that the problem is caused by the oil. The wrong oil viscosity can lead to camshaft timing delays or advance. It is always a good idea to do an oil change first before you try any advanced repairs.
