![]() ![]() ![]() If you're in CALIFORNIA and you’ve taken your Equinox or Terrain to a dealership for issues above, from engine stalling, abnormal oil consumption, high pressure fuel pump failure, balance shaft chain failure or engine failure, we can help you…. The complete recall notice is accessible here. This system benefits your car by raising your fuel efficiency, increasing horsepower, and lowering emissions using the intake and exhaust valves operated by the camshafts. Please ask your dealer if you wish to know how much time will be needed to schedule, process, and repair your vehicle. The variable valve timing solenoid is new technology found in select vehicles as part of the VVT system. Instructions for making this correction have been sent to your dealer. What You Should Do: Please contact your GM dealer as soon as possible to arrange a service date and to assure parts are available. This service will be performed for you at no charge. What Will Be Done: Your GM dealer will reprogram the engine control module and replace the camshaft position actuator solenoid valves. Reason For This Recall: The camshaft position actuator solenoid certain 2011 Buick LaCrosse, Regal Chevrolet Equinox and GMC Terrain vehicles equipped with a 2.4L gas engine may stick, resulting in the illumination of the malfunction indicator light, rough idle, poor driveability, and/or possible stalling at low throttle opening. This notice is sent to inform you that General Motors is conducting a voluntary emission recall that includes your vehicle. The camshaft actuators generally fail due to low or dirty oil, which is related to the Oil Consumption issues that many Chevrolet Equinox and GMC Terrrains have. Just take your time, go slow, and give it some SLIGHT wiggling if needed to aid it in.This is from August of 2011, but I think it's still important to post to get 'out there'. 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. ![]()
