Thanks for your help. I replaced only the sensor, but it was all chewed up
inside. Must have fallen apart sometime ago.
After replacing only the sensor, I still get the P0340 reading and the idiot
light. Should I now replace the assembly with the gear etc?
what usually happens is the shaft/bearings wear out in the whole assy then
it will hit the sensor and break it. Hopefully it didn't ruin your new
sensor. Take off the intake hose, take all the bolts from that big wiring
harness so you can move it out of the way, I could be forgetting
something....sounds like you got it figured out anyway. When I wrote about
marking the shaft on the old and the new I was talking about the
shaft/housing assy....When your done remove the neg battery cable for a few
minutes to clear the code. Have fun.
Did you check yours for play? IIRC the play is what breaks the sensor in
most if not all cases. Given the failure rate I'm sure it would be best to
get a new one but....if you could find a used one in good shape(no play) and
cheap it would be worth a try. You might see if there is a way to grease the
thing too before you install it. I dont remember its been a few years since
I've seen one. Do you know anyone that works at a shop? Does your place of
employment have a maintainace dept/shop? Ask the parts guy at the dealer to
give you a shop discount, lots of times they will if you just ask. Also
search for Ford parts online. Seems they sell them at discount prices, about
the same price as a shop would get it from the dealer. I did a search on a
few ford parts sites but no luck. I think its called a cam sensor drive or
something like that. Good luck.
Dear Shoe Salesman,
I got a wrecking yard replacement and followed your advice about installing
it "do it like a distributor" and even though I didn't have the half
cylinder of metal on the shaft of the old one, I was able to make a good
enough guess as to the alignment and put it in. It is working, I cleared
the codes and they are staying cleared after about 10 miles of driving.
Now, I need to get it past the Department of Environmental Quality (DEQ)
test tomorrow. With no codes it should pass without a problem.
Thanks for your help!
Cool! Here in CA you have to drive the car a while to get the ECM to
relearn before it will pass (smog). (because they check the ECM for being
recently cleared is the best way to discribe it I guess)Its hard to say but
10 miles might do it, just to make sure drive in town and highway a little
at diff speeds. It could be where you are that they just look at the light
to see if it works, and its not on. If it doesn't pass get a printout and
have them tell you why and post here.
