I'll try to give the short story version. 1997 Dodge Grand Caravan 3.8 liter
Was getting a code 54, the code for camshaft position sensor. Autozone tested and confirmed this. Bought and installed new camshaft position sensor. On first test drive, within a block or so, got a bucking and jerking with backfiring. I figured it was the paper spacer on the end of the sensor wearing off. Got the car home, let it idle to warm up and another test drive. Everything working great. Drove the car for 50 some miles last night, ran great, in fact seemed to have more pep than usual.
This morning the wife drove the car to kid's school (a little over a mile) and got jerking and hesitating. Service Engine Light came on. On the way back got jerking for about two blocks then smoothed out and ran normal. Now I get a code 11. Most curious.
Code 11: 11 No ignition reference signal detected during cranking (bad Hall effect) OR timing belt skipped one or more teeth; OR loss of either camshaft or crankshaft position sensor. Can cause the engine to stop working entirely with no limp-home mode.
I'm figuring it's not the cam sensor, doubtful it's the timing belt skipped since it ran smooth last night. That leaves no ignition reference signal or crankshaft sensor.
Any ideas? Is there a way to test for these problems before I start buying more parts?
