Where is the Camshaft sensor position located?

If this car is a 2003 CHEVROLET CAVALIER with with a 2.2 liter engine it does not have a camshaft position sensor. Let us know if you need anything else.

if the obd2 sensor reads the error, there must be a sensor. Im having the same problem.

Yep, the CPS is part of the ignition control module on this engine.
