Hi.
Imposible rear codes of my new 93 Jeep Cherokee 4.0 HO.

With the keys, i do....

ON OFF, ON OFF, ON OFF, ON

and the check engine is in off.. not light...

how is the procedure? Thanks
 
Unplug the CPS and see if the CEL comes back on. Then try unplugging the sync sensor if it isn't the CPS.

A shorted sensor and the CEL may not light.
 
Thanks and sorry for my bad english . What is CEL? perhaps the Check Engine Light?
CPS, is crank sensor position?.. i think yes, anothe time sorry for my bad english. by the way what is sync sensor?
