CPS delete?
I am wondering if anyone has figured out a way to fool the pcm and get rid of the actual cps.
I have been having ongoing issues with my cps. I have tried multiple cps(international) any still experience similar issues with all. Most the time it acts up when its raining or snowing. 2 weeks ago it would want the shut the truck off to the point where I had the leave it at work. The next day I went to tinker with it. Let it warm up without a glitch then driving it, it got to the point where it would shut off every 5 feet. Everything else is up to par, no frayed wires, good hi and low oil pressue, good fuel pressure. The truck with just shut off. No SES. And would start back up just fine. I thawed the truck out that night and havent had an issue since.
I havent heard any issues with the cps mechanically, just the issues noted above. That said, would it be possible to make some sort or resistor to fool the pcm?
thanks,
Josh

Not saying it couldn't be done but....... it'd be expensive. The sensor is magnetic and pulses are read and used to time and control a whole lot of stuff on the truck. I wish somebody could come up with a way to do it. I'd be willing to try it ! Gas engines and most small engines are using a similar and harder to get to version of this approach. I changed a cam position sensor on a Jeep a while back and thought our CPS system was much easier to maintain while doing it. Hope your trouble can be found and fixed. Might be something else going on along with CPS issues.

Josh, are you hearing any abnormal beeping sounds, clicks..etc, within the cab? Reason being, it sounds as though it acts up when snow/rain are present. We (numerous members here) have been in the same situation, and reason being, is the GEM module is getting wet, from, the most part, a leaky front windshield. Unfortunetly, the water drips right onto the module, thus creating problems...

Can't be done, Just about every engine built today has a CPS of some sort. The computer needs to know the orientation of the crank/cam(s) in order to fire injectors, spark plugs, and in some cars the valves themselves. No getting away from some sort of crank or cam sensor.

no abnormal clicks except for the the truck wants to shut off. O have never heard of this "generic electric module" Can this be easily seen, if so, where. Perhaps I might be able to see water damage. I too question its solely the cps because when it last acted up, I replaced it with a brand new sensor and it cut out right away when iodling(in hi idol)

Normally the kit costs $18,000 but you're in luck, it's on sale right now for $16,900.

I have had good luck with mine (grey one). I did two things one by design and one by luck. First by luck I had a rock fly up and hit my windshield and put a giant crack in it that was not repairable. So I had it replace with a new one that seemed to fix the water in the cab problem. Second was I took some clear silicone and put a small bead around the electrical connections. Both where the wires come into the connector and between the connectors once it was plugged in. So far no problems and this is going on two years.

Check the wire harness from the top of the engine to the CPS as well. Mine had all of the insulation missing under the wire loom and the wires were green with corrosion too. I bought a replacement plug/harness at the International dealer.
Also, be wary of certain silicones to "seal" up electrical connectors. Most of them will corrode metal connectors until the silicone is dry.

Make sure there is not alot of dirt, oil sludge, etc. between the sensor and the front cover. It is crucial for the air gap on the sensor to be right. If you have alot of "crud" build up it could hold the sensor out a little and effect the air gap.
I have never seen a G.E.M. cause a vehicle to dike out. The GEM controls power windows,locks,radio,I.P.cluster etc.
