CAUTION to persons using CAGS eliminator- Potential problem.
I recently noticed a check engine light and diagnostics gave me a fault code of PO803. This relates to a problem in the CAGS skip shift 1 to 4 control circuit. Resetting the code turned the check engine light off but it went back on after two cycles of turning the car on and off, which it is supposed to do. The CAGS eliminator that I used was the older variety where there are two black plastic ends separated by 2 black wires which are in turn soldered internaly on one end to a resistor and then sealed in some type of translucent rubbery sealant. Upon physical inspection, I found that the sealant had melted and had dripped onto the exhaust. the device was tied almost 5 to 6 inches from the closest exhaust pipe but obviously too close. I replaced it with another CAGS device that I temporarily borrowed until my new one arrives and the system runs fine without any codes.I would suggest that the next time you put your car on a lift check the CAGS eliminator to make sure it is OK. I do not mean to alarm anyone as I believe the major problem I had was in the location of the install.

There is a more common problem with some CAGS! eliminators. Some vendors have the misconception that the resistor used must be the same low resistance as the CAGS solenoid coil. This is fine, but they then use too low a wattage resistor. The resistor burns up over time.
The PCM does not care if the resistor's value is the same as the coils resistance. You just have to have a resistor that will pull the CAGS solenoid readback input voltage high enough to force a binary "1" for the PCM.

I doubt if many people will have this problem but if it keeps one other person from having a problem then the post did its job. My CAGS was tied to a brake line running on the underside of the floor of the car. I wouldn't have thought it could melt that far away. Its conceivable that my exhaust coupled with some runs on a 90 plus degree day did it in .Its really not important. While I was under the car I noticed that the plug that goes into the tranny was not weather tight so I gave it a Permatex silicone coating. These cags really should use weather resistant connectors but I have not seen any and the General doesn't seem too worried about it either.
