The 2008 Cadillac CTS driving rod position sensor can be found on the right half of the motor under the power controlling siphon on the rear of the motor. The sensor is found right at or underneath the valve cover to the chamber head fixing line which is on the belt side of the motor. The camshaft sensor's fundamental intention is to distinguish the place of the camshaft as it is connected with the driving rod. This information is then shipped off the powertrain control module to use with the fuel injector and start framework control to decide how much fuel it requirements to infuse for burning and power. A portion of the signs to pay special attention to in the event that You assume You have a defective sensor are the check motor light on,issues beginning the vehicle or no beginning,and the vehicle jolting or flood forward while speeding up.
