no it won't work with the ignition system.

sounds like you damaged the harness that goes to the Throttle body if you are truly unplugging the "TPS".

PS our TPS is built into our throttle body, which is making your posts very confusing.

battery tested fine. but i did find a Mazda TSB for the 2003-2004 mazda 6s throttle body. here is the link. http://sdbhost.com/cms/docs/Mazda6s-TBHarness.pdf seems like this is the same issue i may be having, what do you think. my CEL codes are P2135, P2110, P0123, P0223. thanks for all your help

that harness is related to the new TB's that just starting being made. if you used an old throttle body, then it isn't your issue.

ahhhhh thanks for sinking my ship. lol im not sure i will have to look at the part number on my TB. may have been replaced before i bought the car possibly. if so is that something i can make? it looks like all there doing is bridging the yellow and brown wires together.

it is just diode based on what everyone says. later models are already covered for this condition. it also only happens when the car is warm.... during cold start it isn't an issue.
