well if that is the case erm my ECU only throws a code with one componant, the TPS which is pretty busted up, and currently replacing it. I cant seem to find info on pre 90 resistances for the TPS, i mean if resistances are the same then......
One thing i noticed was
MKIII Supra Graveyard has the 7mgte auto ecu/ect all grouped together.
Why i bring this up is my TPS part number is for a 86.5-89... and the 90 sensor doesnt fit the same, the plastic bit on the inside is verticle instead of horizontal if i remember right.
I guess ill just install it and see if engine code goes away if not you think just a throttle body from a 90 and the 90 tps will fix the problem ? lol
