I have been working on this 03 too long. I have tried new crank sensor, new fuel filter, Double checked belt timing because it has been replaced about 20,000 ago(136000 miles) It keeps throwing camshaft sensor code. I did'nt think it would run if it was bad, maybe it will run but not right. Will a camshaft sensor do that? Any help would be nice. Thanks.
Did some tests on camshaft sensor. Getting 5 volts at pin 1 & 3. When I check for power at pin 2 with key on with connector plugged in, I get 10.8 volts and when I turn eng. over by hand it should go to zero when it passes air gap at sensor, mine stays at 10.8 and never moves off it. I ordered a camshaft sensor.
