CPS question


Recommended Posts

Still dealing with my non running 92, and a lot of people have said check the CPS, but i was wondering what it actually does. Yes i know, crank position sensor, and yes i know its on the bell housing, but what am i checking for, and what does it do? I'm sure theres a connection to my problem, but i can't figure that part out

It reads indentations in the flywheel to tell the ECU when the pistons are in the correct position to open the injectors and ignite the coil.

 

If the CPS is bad, the ECU will think the motor isn't spinning, and therefore won't turn on fuel or spark = no start. You can check the resistance with a multimeter, it should read between 125 and 275 ohms.

spray brake cleaner down in the CPS hole while off and running to clean off your pickups on your flywheel just to be safe when your RMS leaks oil and $#!& flys all over the mag pickups and causes it to misfire and whatnot. and sometimes not start.
