if you left the sensor on the front side of the motor then your rear tgv isn't lined correctly. you need to take the sensor off the front then close the tgv, put the motor on then the sensor. the sensor is spring loaded so it needs to be twisted before bolting in. hope this helps but till you do that do not try to beat on your car. it's very possible one side of your tgv's aren't opening. if that's how you put it on then recheck your codes.
