3.0 l v6 base
SOURCE: I have a 1996 Plymouth Grand Voyager SE with a 3.3
The coil pack unit's circuit #3 drives plugs #3 and #6 directly from the PCM. If the cam sensor was defective, it should not fire any plugs. Suspect bad wiring from the PCM to the coil pack, the PCM unit itself, or a segment of the camshaft position sensor surface has lost magnetism causing missing signal to the PCM. An oscilloscope is the best test instrument for chasing down a missing pulse problem. The missing timing signal also explains why the PCM would report a 'bad camshaft sensor'. Hope this helps!
Testimonial: "I appreciate the in depth explanation of what could cause those specific plugs not to fire. I was told to maybe try changing the crankshaft pos. sensor. I figure it can't hurt. Thanks a lot."
