speed sensors
 

Back to the cold weather firing problem. A bud told me that dirty speed sensors will prevent the engine from firing in cold weather. Has anyone had this happen?

CH

true..

What are and where is the speed sensors ?
Thanks for your answers in my engine problems post, I need time to check all the hoses, I hope this weekend ?

I just took mine out and mixed them up I noticed that their is a D stamped and a B stamped on the bell housing and little yellow stickers on the sensors that tell you which one they are.

Good luck to clean up will take bout 1/2 hour

what do the speed sensors do? Do they need cleaned from time to time? How do you know if they need claned, what are the symptons?

Back to the top - help.
We all know that there are two sensor that appear to be megnetic pick-up sensors. One should be reference to top dead center (TDC typical for #1 piston).
What does the otherone do? They appear to work in tandem somehow.
How does the DME use this signal to advance/retard the timing?
Can anyone shed some more light on this subject?
Thx
