Yet Another CPS Thread....food for thought
My truck recently started randomly shutting off and was progressively doing it more and more often. The truck had the recall done 4 years ago to install the improved grey CPS. Back when it was installed, I noticed that my TS HUD RPM reading while at idle would lock on a number anywhere between 700-1100rpm and would not fluctuate until revved past the number. I never really paid this much mind as the truck ran alright but always had the surging/miss at idle and mileage decreased. Since this latest issue, Ive been reading up on everyones opinions and experiments with the different CPSs and the conclusion I have come to is that the original Black(big magnet) CPS is MUCH better than all the rest minus the fact that it will leave you stranded when it fails. Coming to this conlcusion, of course I immediately start searching for a genuine International black CPS but they are LOOONNNGGGGG gone so I start searching for alternatives and found that the aftermarket companies are still manufacturing black CPS replicas. Im not one that would usually purchase anything other than OEM parts in this case but at just $22 shipped for the Standard Motor Parts PC139 sensor(what I read to be the best of the aftermarket options) I decided it was worth a try AND............................................... .... My rough idle is gone, truck runs smoother and stronger, sounds much better when the converter is locked and you load the motor at low rpm, the HUD has an accurate rpm reading at idle that fluctuates ~10rpm as you would expect, and I will find out if mileage increase as time passes and of course I still keep a recall CPS in the glove box.
Sorry for the long winded thread but I was pretty excited about this. Hoping my mileage improves considerably.
P.S. does anyone have any experience with any aftermarket black CPS? I cant seem to find any threads where someone has done a PERDELS test on the aftermarket sensors.
