the z6 in my ef is throwing map, tps and iacv codes... sounds a little odd to me.
it's converted to multi-point, and obd-1.. running a chipped p28

i threw the map sensor on a running car and it didn't cause any problems or throw any codes.. so i have a feeling the sensors are all good.

could my chip be the problem, or the wiring, or...??

any ideas?

 

any ideas?

 

i'd check all the wiring first, it's possible something is not hooked up right or perhaps a wire came undone or melted. also, make sure that the iacv and the iat (white sensor on the back of the i/m) aren't switched, same with the map and tps wiring, then go from there

 

TPS and MAP are easy to get mixed up.
