P0011 – Meaning, Causes, Symptoms, & Fixes

Code P0011 Definition

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

What Does P0011 Mean?

Variable Valve/Camshaft Timing in the internal combustion engine control the intake and exhaust gases in and out of the gas combustion chamber. You want to vary the way your engine operates at different points of the engine’s rev range. Varying the different valve events: valve timing, valve duration, and valve lift allows the ECU to constantly make a call to the most power, the best mpg, and the lowest emissions. The different pistons that pump up and down leave the exhaust valves with the maximum air space that the engine can take in fuel and air to give you maximum power. When trouble code P0011 is set, it means that camshaft position “A” in Bank 1 is more advanced than the ECM has told it to be.

P0011 Symptoms

  • Check Engine Light
  • Hard start of the engine
  • Rough running engine
  • Increased fuel economy
  • Failed emissions test

P0011 Causes

  • The exhaust shaft has advanced too much when the ECM has told it to slow down to a lower timing level.
  • Camshaft variable timing solenoid failure
  • Camshaft phaser is seized in the advanced position
  • Continuous oil flow to Variable Camshaft Timing chamber
  • Viscosity of oil is too thick or too thin

Code P0011 Severity – Moderate   

The engine may have erratic and other engine problems that could affect driving and fuel economy may decrease due to increase fuel consumption. As for any Diagnostic Trouble Code it should be repaired as soon as possible for no internal damage.

Code P0011 Common Diagnosis Mistakes

Replacing sensors or components without any indication of a problem with the sensors or components.

P0011 Diagnosis

  • Tools Needed to Diagnose:
    • FIXD
    • Car specific service manual

Difficulty of Diagnosis and Repair – (1-4)

  1. Visually inspect the connector, wiring, or valve problems with the Oil Control Valve for bank 1 exhaust valve.
  2. Check the engine’s oil level and viscosity to see if they are correct.
  3. Check the live freeze frame data
    1. Monitor the timing of the data and disconnect the Oil Control Valve to the exhaust camshaft. If there is a change it means that the valve is working correctly and there is an electrical problem within the ECM.
  4. Find your vehicle specific service manual and follow the pinpoint tests to repair them as needed.

Every time I get this code when Advanced Auto checks why my check engine light is on, I tell them it means I’m way past an oil change. EVERY time I say that, they tell me an oil change isn’t going to make the light go off. Sure enough…. an oil change makes it go off…. until I’m VERY late for another oil change

Hi Jalaine! It is extremely important that you use the correct oil for you vehicle every time you change your oil. We suggest consulting your owner’s manual to find out what will work best for your specific vehicle.

Thanks, FIXD Team

Hello, I got the same code for my Chevrolet Equinox. I’ve had the oil change & the like is still on. Same code. I’ve had both sensors changed & it’s still doing the same thing. Can someone give me an idea as to what to check next ?

A year ago I took my car into the dealership because when I was on the highway my car kept getting “stuck”. My foot would be on the gas and I could hear my engine reving but I would slow down. I took it into the dealership (because my warranty was almost up) and they told me it was “normal”). Fast forward to now, I bought FIXD and I find a camshaft issue. Should I be concerned that after all this time being ignored has severely injured my car?

Where exactly is the P0011 intake camshaft position sensor located on a 08 Pontiac G6 GT ?


February 18, 2019

I had Advanced Auto parts to hook up a computer to see what caused my check engine light to come on. P0011 was the diagnosis.
However, the light went off as soon as I restarted my car. Should I proceed to try to fix the problem or not do anything because now my check engine light is off again?


February 23, 2019

Sometimes when using a OBDII/EOBD the check engine light will go off but after certain miles the computer will reignite the code and catch a misfire and check engine light will proceed to come on, I suggest you get your car fixed before problems proceed usually po11 code can lead to loss of engine power , high RPMS, very high low mileage, large consumptions of gas. Sometimes it can be the oil filter , oil change, solenoids, or camshaft sensors

I have had the issues with the rear main oil seal, blowing out and losing all the oil in my 2014 Equinox. Had it fixed three times and when I got it back from the shop, check engine light was on with code P0011 stored. Since I always ran a synthetic oil in the engine, I would bet my left %#& they charged me for the synthetic oil, but put in the cheap crap. Where exactly is this sensor and will the crappy oil they put in , be the suspected culprit? I bought my FIXD several months ago and it’s a blessing in disguise. I HIGHLY RECOMMEND this product to EVERYONE!!!

I have a 2008 Saturn Aurora my check engine light keeps coming on and off and my oil change light keeps coming on and saying oil consumption 0% I did a oil change and the light for oil change still never went off it’s still saying I need a oil change also I got gas from a gas station that’s known to make cars run a little crappy cuz the gas is trash and ever since then my cars been running a little hard. When I go to take off it’s kinda puttering but stops after a few seconds so I went to auto zone and hooked it up to the diagnosis machine and 2codes poped up po306, cylinder 6misfire detected and poo11intake camshaft position timing -over-aecanced (bank 1) can someone please tell me what this could be and is it an exspensive fix??


October 1, 2019

I think you did not successfully reset your oil change counter so it is telling your computer the oil change is overdue and that triggers the computer to display the p0011 code. Setting the oil change counter to 0% is not enough. Once you set the counter to 0%. Press and hold the reset buttons until the display says the reset has been acknowledged . The codes should go away after a bit.
Here are the complete reset steps:
Turn the ignition to the “RUN” position.
Press the “INFORMATION” and “RESET” buttons at the same time to enter “PERSONALIZATION” menu.
Press the “INFORMATION” button to scroll through until “OIL LIFE RESET” is displayed.
Press and hold “RESET” button until “ACKNOWLEDGED” is displayed.
Turn the ignition off.

What happens if you bank 1 vvt solenoid in bank 2


July 9, 2019

This code popped up recently and is my only one. I needed oil for at least 3 days since the oil light popped up then the service engine light turned on after. I just got and oil change today. Do you think it will go away? Or I might need to start saving money?


July 21, 2019

Got this code on my girlfriends car. Checked the oil it was low. Cleared the code and hoping it runs better. Will replace the sensors next if problem doesn’t go away. Really enjoy having this FIXD device.
