CAM RELUCTOR-WHEEL BLUES
On the 2006-2016 GM 2.4L Eco-Tech engines, beware of the reluctor-wheel attached to the intake and exhaust camshafts for the cam sensor. These are just pressed on. If they get hot and lose their press fit, they will come loose and move. The engines will run poorly and throw codes due to the timing being off on these sensors. It appears the camshaft(s) need to be replaced to fix this.
