Oil change cause check engine light?

[Euge]

Last night I changed oil and filter on my 2015 Encore and this morning the check engine light is on. Any connection?

Have no way of knowing unless you determine what the code is.
Did you use the correct viscosity oil and the correct oil filter?

Excuse me. I'm trying not to sound like I'm insulted. My question was if there is any connection to the oil change monitor and the check engine light? And yes, correct oil and filter. I ran it last night to check for leaks and when my wife drove it this morning, the check engine light came on. Auto-zone found the code was P171, Bank 1, intermittent lean condition. It went off as soon as I connected their meter. Thanks for your response though.

There is no connection between your oil change and your check engine light. Pure coincidence. P0171 can be caused by a dirty air filter but I assume since you change the oil you also checked your air filter. Dirty MAF sensor or HO² sensors getting old and beginning to fail.

 

[MelsRegal]

The reason I asked about the oil and filter is because the camshaft solenoids can be sensitive to wrong oil pressure due to viscosity issue or filter issue which would then throw a code.

Thanks, I doubted any connection with the two and I will check the air filter and maf sensor.

What's a camshaft solenoid?

 

[MelsRegal]

What's a camshaft solenoid?

Your engine is equipped with VVT, variable valve timing. The solenoids use oil pressure to shift the position of the camshaft based on signals from the ECM .

So it advance/retards timing by electric solenoids or hydrolic oil pressure? Which one, or both?

 

[Again]

Beg to differ MelsRegal but these cam actuators are electronically controlled and oil has no say. Codes P0010,P0011,P0012,P0013 would be set if a problem with these would occur. There's an actuator for each cam.

I recommend you read this link amoung many articles that explains the role of oil pressure in how VVT functions.

Do a scan and eliminate guessing.

It advances and retards the camshafts with a combination of both, read the article above.

This article talks about older GM V8 and V6 with a different setup than the 1.4l turbo ecotec in the Encore. Timing on these is done electronically with mathematical calculations depending on all parameters including load, rpm, boost and many more. Oil pressure may be one of them but I doubt. Although these are refered to as solenoid they aren't they are actuators controlled by stepper motors.

You are correct that the solenoid is not used in the 1.4, only 2.0 and 2.4.

And the 2.2l ecotec you find in most Cobalts, G5, Ion, HHR, Solstice, Sky and more...

You are right.. my 2015 verano check engine light came on and was told that exact thing.. took it up and had oil changed and light went off immediately after the oil change and has not came back on..
