37,505

The code is low voltage for cam sensor. This is a rather involved code to trouble shoot. A scanner is need to conduct all tests necessary. From my experience it has always been a bad sensor. This does not rule out a connection problem at the sensor or computer so really all you can do without scanner is unplug/replug computer, do same for cam sensor. If the light still returns, suspect bad cam sensor. Usually if there is a wire connection problem, work was recently done to engine, wires unhooked, etc. If all has not been handled recently, this makes it more probable the sensor is the problem.
