Note:Do NOT remove or back out the camshaft position actuator bolt(s) significantly, simplybreak them loose from their fully-torqued position. This puts the camshafts on “base circle”and will reduce their tendency to rotate from valve spring pressure when the camshaftposition actuators/drive chains are removed.

Just take your time, go slow, and give it some SLIGHT wiggling if needed to aid it in.Chevrolet Equinox Service Manual / Powertrain / Engine / Camshaft Position Actuator Replacement - Bank 1 Valvetrain Camshaft Anyone who hasn't ever had this part out before, when reinstalling you might note it feels a bit snug. It seems daunting, pulling something out of the side of your block that is a pretty important part, but it's not bad at all. This guide, while I didn't do the cleaning part of it, certainly helped me build the confidence to go through with this project. I'll tinker with the old part some more, if it turns out it's still usable I might hold it for an emergency replacement. Usually by the time I was almost to work (20 minutes of driving) the code would be confirmed, it would usually be pending by 5 minutes before. I could have cleaned mine, except the pressing that combines the outside half to the inside half appears to have partially separated as I could rotate them independently. Replaced, and after two days of 40-minute round trip drives to work, it appears to have satisfied the condition. The voice in the video is reaaaaalllly annoying, but gives a decent explanation of the system: The phaser has some parts around the outer radius that relays this information to the sensor. The position sensor also is unrelated to the timing chain, it's pretty much a little doo-hicky that picks up magnetic signals. The CPAS just pretty much acts like a valve to direct the phaser's motions. The actual actuator (or cam phaser) is a part on the end of the exhaust camshaft, directly connected to it (and thus the gears and timing chain) for the purpose of working the angles. The CPAS is not an actuator, it's a solenoid that supplies oil TO the actuator. No, but if the system detects you're holding the gas pedal in one position and the butterfly's stuck in another, you'll get the REP light, so it pretty well figures itself out.Īs for the timing chain retention: This is for the ACTUAL ACTUATOR.
