Crankshaft position sensor ? 94 Cherokee

I have a 94 Cherokee that stalls during warm up. Will usually restart immediately somtimes have to wait a minute or 2 but will not fail once it is up to operating temp. After reading other posts here it sounds like CPS. I do not get a check engine light or any codes. How can I check it and will it store a code?
Any help is greatly appreciated.
Thank You

HI IT SOUNDS LIKE YOU NEED TO GET A CAN OOF SPRAY CARB. CLEANER AND CLEAN THE IDLE CONTROL VALVE THERES A SLOT IN THE BACK OF THE THROTTLE BODY BORE. USE THE LITTLE STRAW ON CLEANER CAN AND SPRAY CLEANER INTO SLOT ----KEEP THE ENGINE ON A HIGH IDLE DON'T STALL IT. IT WON'T SET A CODE HOPE THIS HELPS DALE [email protected]

sorry,but i beg to differ,you want to use throttle body cleaner only,carb cleaner will leave a gummy residue,that is not good for the injectors... :2cents: :sunglasse

Not sure your problem is the CPS, but here's a link to a page with a test procedure.
