Rough GM Engine Check Engine Light Whats P0014 And How to Fix It

In this video, we have a 2012 Cadillac SRX with a check engine light, with a P0014. That's what we're going to talk about in this video.

This video will apply to most GM vehicles that have the same 3.6-liter V6 engine. The code we have on this vehicle is the P0014, which is the exhaust camshaft position performance code on bank one. This engine has VVT or Variable Valve Timing. And what that does is that gives you extra horsepower and fuel mileage in such a small engine.

Basically, you have rotating components inside the engine, and the computer needs to time those components. And if those components are not timed properly, that's when you get these codes. One of the potential causes for this code is the camshaft position solenoid valves, which are located on the front of the engine. On this engine, you have four of these solenoid valves. You have two on the back and two in the front. This lower one controls the timing for the exhaust. This upper one controls the timing for the intake.

Now, how this work is with redirecting oil pressure or oil flow. So, guess what? If your oil level is low, or your oil is not up to par, they're not going to work right. Before you go changing any of these components, you want to check your oil level. Make sure it's not low, and make sure the oil looks good. If you've neglected to change your oil, or it was extremely low, the damage is probably already done, and you're going to need to change those solenoids.

Here's what the solenoid valve looks like when it's out of the vehicle. Here's where the oil goes in, these different passages. And what you want to check for is to see if you see any metal particles in here. And I don't see any metal particles, which is good. If you see metal on these screens, there is more internal engine damage, and you're going to have to go deeper into the motor than just changing the solenoid valves.

So, changing that camshaft position actuator valve and changing the oil should fix your problem. A good way to prevent this is to keep up on your oil changes and double-check your oil level regularly.

What we're looking at on the scan tool is the desired camshaft position and the actual camshaft position. And if you have the ability to change the timing of the camshaft, they should follow each other. And if they're not, there's something wrong with that solenoid.
