The blade opens wider when you step on the gas to allow more air into the engine. It has a moving flap called a throttle blade that’s connected to the gas pedal.

The throttle body controls the quantity of air getting into the engine when the driver steps on the accelerator pedal. Throttle Body and Accelerator Pedal Codes Oil that is low or of poor quality can cause the valves to go bad. Remember to lubricate the new solenoids before sliding them in and ensure your oil is at the recommended level. They each have a unique part number and cannot be interchanged. You’ll have to replace them with new ones. The valves are held by a 10 mm bolt just below them.Ĭlean out any debris and unscrew the solenoids. All you need to do is first pull the engine cover off and disconnect the solenoid connectors. One is connected to the intake camshaft and the other to the exhaust camshaft. There are two VVT solenoids that control oil flow in the four-cylinder engine. You may end up with an engine P0010 or P0011 code. Their failure is more common in the four-cylinder Chevy Equinox and can even cause the vehicle to stall. The VVT solenoids help to control the flow of oil depending on the load and speed of the engine. Exhaust and Intake Variable Valve Solenoids You’ll have to take the engine’s cylinder head(s) off, pull out the pistons, and replace them. Replacing the piston rings is a relatively challenging task. This then causes excessive oil consumption. When they get stuck inside the pistons or fail to seal properly, the oil will get by and burn. They also regulate oil consumption by removing excessive oil from the walls and sending it back into the sump.
These rings help to maintain the right quantity of oil between the cylinder wall and the piston. One of the things they do is to replace piston rings that are not sealing properly. General Motors has a technical service bulletin (TSB) for excessive oil consumption in the 2010-17 Chevy Equinox.
The main culprit behind this is usually a bad rear main seal which causes oil to leak just near the back of the oil pan where it meets the transmission. Oil leaks are also a pretty common problem in the second-generation Chevy Equinox. This then causes the amount of oil available to decrease at an abnormal rate. A valve seal that’s damaged will cause oil to leak out and get burned excessively. This keeps the air/fuel mixture clean and prevents contamination. Valve seals prevent oil from getting to the engine’s combustion chamber. If you see a lot of oil running through the PCV valve, you may need a new valve cover. You want to check that your positive crankcase ventilation (PCV) system is working properly. If this is your case, here are a few places you can check: However, a lot of users have complained about having to add up to four or more quarts per month. General Motors states that your Chevy Equinox should run less than one quart of oil within 2,000 miles. This is one of the more common problems encountered in the Chevy Equinox that runs on the four-cylinder engine. A way to prevent this is to change your oil regularly and ensure it’s always at the recommended level. If the tensioners are pushed out a little bit, then the chain is definitely stretched. You’ll need to take the front part of the engine apart to access the timing chain. It is one of the most common Chevrolet Equinox problems that is also difficult to diagnose.
This normally means that you have a timing belt that is worn out or stretched.

Other common signs that will indicate there is a problem with the timing chain in your Chevrolet Equinox is if you get an Engine Position Performance code or a Camshaft Position Performance code. The car’s computer will then think that something is wrong and bring up a Check Engine light. If it’s stretched, it will distort this process and affect the timing. If the timing chain works properly, the valves will open and close just in time. To make sure they open and close at the right time, a timing chain is used to connect the camshaft to the crankshaft to ensure the two are rotating in synchrony. The intake and exhaust valves are controlled by the camshaft. This expels the burnt gases through the exhaust valve. The downward push then causes the crankshaft to rotate, pushing the piston back up. The combustion process releases gases that push the piston down the cylinder. Once inside, the mixture burns to release energy. A mixture of air and fuel get into the cylinder through the intake valve. Timing Chain in V6 EngineĪ typical combustion engine consists of a fixed cylinder(s) and a moving piston(s). Save Up to 50% Off Chevy Equinox Auto Parts and More Common Chevrolet Equinox Problems 1.
