I put in the .50 version of the Skip shift eliminator on about a week and a half ago and the "Service Engine Soon" light came on yesterday. I took it to the dealer to hook it up to the computer to see where the problem was. It failed emissions and the guy at the dealer said the computer is running the engine too rich due to the eliminator. From all of the threads I have read on this, I have not read anything about the Service Engine Soon light coming on. I am thinking the engine is running rich only when I use 2nd when it wants to go to fourth gear instead. The computer would not make the engine run rich all of the time would it? What a pain in my A-hole!

Would anyone like to elaborate on this for me??

DTC P0803 is set when the skip shift driver doesn't detect the correct change of state when it expects to see it (open circuit, which is why you put the resistor in) but all that happens is that the code is recorded, no MIL is lit, and there are no other actions, so your other issues are coincidental. Only an O2 eliminator would be implicated in a rich condition.

 

Thanks for the reply. so you are saying that the SSE is not the problem but I have a problem with my O2 sensors?

 

Not necessarily, just that the SES is being set by something other than DTC P0803. It's just that with the guy saying the 'eliminator' was the cause, O2 'eliminators' used when the rear sensors are removed may be what he was thinking...

 

OK - I think you are saying that the only time I would get a rich condition is when I had O2 sims or eliminators - which is not my case. I have done nothing to the O2 sensors by-the-way. I don't have aftermarket headers either...Still kinda confused but I think I know what you are saying..

Thanks

 

what he was saying is the person was full of it...... take it elsewhere for a 2nd opinion. thats wut i would do neway
