p0011 code,check engine light one, changed bank 1 vvt solenoid and check engine light still on?
service engine light on, pulled p0011 code, change bank 1 solenoid and check engine light came back on in same amount of time it came on with old solenoid also.spoke to few mechanics and 1 said they need to clean potential dirty oil and another mechanic said it could be timing and another mechanic said he open oil cap and with a flashlight looked inside engine and said it looks clean and probably not engine sludge. Need help with potential issue and fix before i pay for expensive mechanical guesses
Experienced mechanics share their insights in answering this question :
The P0011 code is typically caused by oil issues with the car. I would particularly make sure the engine oil level is not low. The VVT solenoid relies on proper oil levels to do their job. If they don’t have enough oil, they won’t work. You can have a mobile technician from YourMechanic visit your home or office to inspect the Check Engine Light for you. If you follow through with a repair with us you will be reimbursed for the cost of inspection.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The camshaft(s) is(are) adjusted by the engine computer through the use of an oil control valve(s) (OCV), also called variable valve timing control solenoid valves. When trouble code P0011 is set, it means that the intake camshaft in Bank 1 is more advanced than the engine computer has told it to be.
If you`re seeing engine code P0011 on your vehicle, it means the intake camshaft in Bank 1 is in the wrong position. Your intake camshaft controls whether the intake valves on your engine are open or shut.
The “A” camshaft is the intake camshaft on the left or front of the bank from the perspective of the driver. Bank one is the bank of cylinders that contains cylinder one. This code indicated that the camshaft timing is above the threshold, also called being over-advanced.
When trouble code P0011 is set, it means that the intake camshaft in Bank 1 is more advanced than the engine computer has told it to be.
If the Engine Computer (ECM/PCM) notices that the cam timing is too far advanced and attempts to set a target to correct that incorrect angle but the Cam and Crank sensors indicate the angle didn`t correct or didn`t correct fast enough, the P0011 code is triggered on bank 1.
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. This over-advanced condition could be during advancing or retarding of the camshaft timing.
You can drive with code P0011, but we won`t recommend that. Avoid driving your car until performing the essential repairs, as the code can cause severe damage to your car`s engine parts. Ignoring the P0011 error code in your car will result in several drivability issues.
A P0011 code indicates that the intake camshaft is consistently running more advanced timing than the engine computer has commanded. Usually, you should also notice a rough-running condition, poor fuel economy, emissions problems, hard starting and hesitation along with this problem.
When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you`ll advance the timing by rotating the distributor counterclockwise, and vice versa.
The ignition timing error is typically caused by damage internally like the pistons or valves inside the engine. A loose or weak engine timing belt that jumps time can cause the ignition timing to be off.

A lack of oil pressure can cause this code to appear. If there is low oil, like from having oil leaking or burning, the VVT solenoid doesn`t send a message to the computer to advance the timing, and this can lead to a check engine light, and a ticking sound or rough running engine.
Bank 2 is typically found on the passenger side on the engine block. The solenoid should be located near the intake side on the engine head. Variable valve timing is an important feature on modern engines. This system uses the ECM to control the intake and exhaust valve solenoids to change valve timing.

p0011 code,check engine light one, changed bank 1 vvt solenoid and check engine light still on?
ANSWER : The P0011 code is typically caused by oil issues with the car. I would particularly make sure the engine oil level is not low. The VVT solenoid relies on proper oil levels to do their job. If they don’t have enough oil, they won’t work. You can have a mobile technician from YourMechanic visit your home or office to inspect the Check Engine Light for you.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.
Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.
To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor
ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.
O2 sensors changed, but check engine light still showing code after clearing it I checked fuse. Wires are good and used Denso OE.
ANSWER : Depending on what the code was for will determine if the oxygen sensor was to be replaced. If the conditions were for a rich or lean mixture and it said oxygen sensor, then the spark plugs and wires could need replaced if its a rich reading or the fuel injectors could be clogged or not working if its a lean mixture. If the code said that the oxygen sensor was bad, then check the harness and see if there is a break in the wiring or a short to ground in the wiring from the oxygen sensor to the main harness. If you need further assistance with your check engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.
VVT (variable valve timing) Solenoid and Check Engine Light codes P0300 and P0011
ANSWER : Hi there. Through your research you probably discovered that there are multiple causes of a rough idle and the Check Engine Light beyond the VVT solenoid.
If you replace the second bank solenoid, it may improve your issue, but it’s impossible to know for certain. Also, anytime you have a Check Engine Light illuminated, it’s due to an error code being triggered and stored in the ECU. In order for that light to go away, you’ll have to contact a professional mechanic to reset the error code with a digital scanner.
If you need help trying to diagnose the reason why you’re engine is running rough, contact one of our professional mechanics who can inspect your rough idle issue, make the right repairs, and reset the error codes during one trip.
Check Engine Light is on, trouble code P0011&12. I changed the oil and filter. I need to turn off the engine light to see if that problem is solved.
ANSWER : Hello. If the oil level was low or if the wrong oil war previously used then that can cause these codes to come up. Most of the time though, on this engine, it is caused by a failure in the timing chain. The timing chain is the most common failure on this engine and when it is stretched enough the cam timing will be off enough to cause this. If you want to have this camshaft timing looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose why the check engine light is still on and address any issues that are found.
While driving on freeway truck goes into a limp mode, and the check engine light, abs light, parking break light, service brake
ANSWER : It is possible that you could be having an issue with your powertrain control module. This is somewhat of a common problem on many GM vehicles. I would recommend having your vehicle inspected by the dealership to determine if the powertrain control module is functioning properly. If not, a reflash of the powertrain control module may resolve the issue but often times it must be replaced.
Traction light/reduced engine power and check engine light coming on
ANSWER : Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.
