![]() A rattling sound can also indicate the timing chain jumped a tooth. Rattling Sound– You may hear the camshaft actuator rattling at idle speed since it’s not where it’s supposed to be.Poor Idle Quality– If the camshaft actuator fails while it is too far advanced, it’ll idle roughly.Here are some of the typical symptoms of P0011 in the Chevy Equinox: When the cam timing is off, it can cause some issues with the motor. It’s usually the cylinder head closer to the front of the engine. If your Equinox has a “V” engine with two cylinder heads, 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. 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 P0011. Sometimes, the system will get stuck in an over-advanced position. VVT allows the engine to act as though it has different camshaft profiles at different RPMs this is great for both power and fuel economy. Vehicles with VVT can change camshaft position timing depending on whether you need power or economy. The camshaft’s position is constant relative to the crank’s position on vehicles that don’t have variable valve timing. Camshaft Position TimingĬamshaft position timing how your Chevy Equinox’s intake and exhaust valves close relative to the location of the crankshaft. Here it is separated into its separate pieces, with a quick explanation of each. The technical definition of P0011 for the Equinox is “A” 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, VVT Intake Solenoid, timing chain/belt jumped Stalling, decreased MPG, rattling, engine running rough, check engine light P0011 “A” Camshaft Position Timing Over Advanced or System Performance (Bank 1) P0011 Trouble Code: Quick Info Definition If the oil level is too low, the camshaft actuators won’t work properly. The first thing you should do when you have this code is check your Equinox’s oil. ![]() It indicates an issue with your vehicle’s Variable Valve Timing (VVT) system. In fact, P0011 is observed on the Equinox MORE than any other vehicle. P0011 is a common (and serious) OBD II diagnostic trouble code that can occur in the Chevy Equinox. ![]()
