I have done some searching and cant seem to kind the right answer to my problem so ill give it a shot here...
i ripped my upper engine wiring harness in half and blew my ecu on my 92 se hatch, So i got another #30 ecu and another harness.. the harness i got was a little different then the one i had, it had a extra plug near the ecu about 1 1/2 inches long with foam around it. and another extra plug near the TPS/ coolant sensor its a 3 pin black plug. and the tps sensor was alot different..
So me being ancy i decided to swap the tps plug for my original one and hook it all up and see what happens, so i do that and the car starts but idles around 1000. i turned the car off and back on and i had a cel. i then drove the car and it was loud as balls and had no pull at all... so i read the ecu and got 43, 12, 34.
so the ecu isint seeing my tps, maf or knock sensor.
So my questions are
1. What harness did i get
2. Is it because of the harness that im not getting a reading from these sensors
3.is it the sensors them self's
4. Could i rewire the harness a little to get it to work
what i mean is would the harness forsure do this? before i start buying new sensors...
i can post pics if necessary thanks for any help :)
