Hello, I had since replaced original cam position sensor with two aftermarket sensors. The new ones come with a spacer at install, but why do these go bad prematurely? Thanks in advance, Al
I would add that in recent years, I've come to trust parts by A.C. Delco in their "Professional" line. They also have their "Advantage" line, which are the economy grade. I've learned from experience to trust their Professional line.The "economy" line cam and crank position sensors may only last about 25K miles at best. Even the OEM and premium aftermarket sensors cam/crank can start to give bad signals around 40K miles. You need to buy the premium brand, because any parts coming from Commie China (PRC) these days for the economy lines at stores like Autozone are junk. Standard Motor Products makes good sensors, but you have to get their premium line parts, not the economy line. If you still have a Carquest parts store, they carry SMP, but Advance Auto took them over and closed many of the stores (morons). You can check Advance Auto and O'Reily websites, but again look for the premium (more expensive) parts. And take in a printout if you go to the store because a lot of the young guys at the stores are inexperienced with lookin up parts. Or the premium line at NAPA may be SMP or another decent brand. You can also check your local Dodge/Chrylser dealers for the Mopar OEM part, but like most dealer parts it will probably be more expensive - if they even stock them anymore. And the Mopar part would have been made by SMP or othe aftemarket company anyway.
Super odd thing, I had to replace the cam sensor on a 1G 3.5. Left spacer on. Car would not start. I removed spacer, made a guess at depth (bottomed out, then brought up just a smidge) and it fire right up. Forget the brand.They're supposed to come with spacer. You left the spacer on when you installed it - right?
"Aftermarket" may be the problem.
