It’s usually the cylinder head closer to the front of the engine. You’ll need to look up which side is bank 1. If your Equinox has an inline engine, you don’t need to concern yourself with this.īut, if your Equinox has a “V” engine, it’ll have two cylinder heads. Bank 1īank one is the side of the engine with the first cylinder. Here’s a detailed write-up on exactly how VVT works if you’re interested in learning more. Some simpler systems change the cam timing, while others change cam profiles entirely. They are hydraulic, which means that they use the vehicle’s engine oil to change the intake valve timing. Valve timing control methods can be quite different for every engine, even from the same manufacturer, but the basics are the same.Ĭamshaft actuators or phasers change how long the intake and exhaust valves stay open.

When this happens, your Chevy Equinox will store trouble code P0014. Sometimes, the system will get stuck in an over-advanced position. It can advance or retard the timing at will. VVT allows an engine to act as though it has different camshaft profiles at different RPMs this is great for both power and fuel economy. Adjusting the camshaft timing allows an engine to have a better power curve and better fuel economy (the automotive equivalent of having your cake and eating it too).ĭepending on the vehicle, the “B” camshaft is the exhaust, right or rear camshaft. “B” Camshaft PositionĮngines equipped with VVT use camshaft actuators (they’re often called phasers) to adjust the position of the cam. Here it is separated into its three main pieces, with a quick explanation of each. The technical definition of P0014 for the Equinox is “B” Camshaft Position Timing Over Advanced or System Performance (Bank 1). Not usually, but in rare cases, the underlying causes can damage the engine. Low oil, wrong oil viscosity, faulty camshaft actuator, timing chain/belt jumped Stalling, decreased MPG, rattling, engine running rough, check engine light “B” Camshaft Position Timing Over Advanced or System Performance (Bank 1) P0014 Quick Reference Table P0014 Definition Low oil is the number one cause of P0014. P0014 means that the camshaft position is too far advanced from where it should be in relation to normal operating specs.īefore doing anything, check your Equinox’s oil level. VVT adjusts the position of the camshaft(s) to maximize the combustion efficiency of the motor. You have been a blessing and I appreciate all the info and feedback you have given me.P0014 is a relatively common trouble code for vehicles that have Variable Valve Timing (VVT). I ordered my parts because I can get them cheaper online but I will message you once I have replaced them so if anyone comes across this thread maybe it could assist them. This car is a bit of a learning curve for me because of the added battery and electric motor. First thing I did was throw some new iridium plugs in it and check things over. It had 103,000 miles on it and I bought it at 97,000. I don't believe they are bad because I don't hear then and know this car had been really well maintained (which I know doesn't always mean anything). If these don't fix it I guess I will have a spare fuel pump and will then need to look at the camshaft. I went ahead and ordered a new hpfp along with a camshaft position sensor. This is one of those things that im finding very little information on. I don't typically reach out to others as I research and try to learn on my own. I just wanted to thank you for all your help. Let me know what you find or if you have questions. Perform the fuel rail pressure relief valve reset procedure if supported on the scan tool. Intake camshaft and valve lifter replacement

Perform the diagnostic repair verification after completing the diagnostic procedureįuel injection fuel rail pressure sensor replacement. If less than infinite resistance, replace the high pressure fuel pump. Test for infinite resistance between each terminal and the G18 High pressure fuel pump housing. If not between 9-11 ohms, replace the high pressure fuel pump. Test for 9-11 Ohms at 77Â F between the high control circuit, terminal 2, and the low control circuit, terminal 1. Note: The DMM and test leads must be calibrated to 0 ohms in order to prevent misdiagnosis. Ignition off, disconnect the harness connector at the G18 High Pressure fuel pump Test or replace the G18 High Pressure fuel pump If the loves have unusual wear or are worn, replace the camshaft. Verify the lobes on the camshaft do not have unusual wear or are worn. If something fails during the test, I can direct you from that point. Go through them and let me know what you find.
The code indicates the fuel pressure is too high, which I believe you already know.
