Well, it's about time. Car stalled at redlight, then started again, limped home, threw the OBDII reader on and got 0335, CPS. Fortunately, thanks to the forum I am prepared with a replacement Bosch sensor and appropriate tools. Just waiting for the car to cool down and then to work. Sure glad this didn't happen on the way to Carlise, I would have had to make up a country song about it! LOL

 

Nope.
Country songs are ONLY about trucks, women, drinking or prison/jail.

 

I was thinking something like "I dropped a pile on the way to Carlisle. Almost as bad as walking down the aisle." ????

 

And Dogs....dont forget the Dog.

She took my money...stole my truck and ran over my dog. Thats when I killed her and went to jail...

 

Ummm.. yeahh... sounds like you might want to keep the day job..

 

What day job? I are retired. I was tired once now I'm retired. As a friend of mine related, his wife asked him what he was going to do one day and he replied "nothing", she said you were doing nothing yesterday, to which he replied, yes but I didn't finish.

 

Jim, How many miles on the XF? I assume this is your first CPS replacement.
Retired, doing Nothing tomorrow.

 

It has 46+K on it and yes, this is my first CPS. Car cooled down, replaced the sensor, checked OBDII, no codes, all seems well. My car had a plastic shield attached to the bell housing which made any tightening by hand, impossible but I used a small ratchet with a long extension and it didn't take long, about 15 minutes. I have a question for the real brains here, what is it that goes bad, it does not appear to have any moving parts. I was wondering if a good cleaning of both the sensing end and plug contacts with electrical contact cleaner would make it perform as new. Anybody know?

 

It is a magnetic reluctance pickup, excited by teeth in the flywheel.
( used to be called a 'reluctance head' pickup back in the day )
Cleaning the sensing end would have NO effect.
I think the problem is one of two things :
1. The engine vibration and heating/cooling cycles eventually causes a break in the internal coil wiring around the permanent magnet
or
2. The harness contacts just get dirty/corroded, unplugging and putting in a new sensor fixes that.

 

Thank you for that info. I think that I will do a clean up on the old one and this winter, when I have nothing to do, I will try replacing it on the car and see what happens. Of course I will buy another Bosch to have on hand.
