What conversion harness do you have? OBD0 or OBD1 map sensor location?

 

What?

I have the Non OBD to OBD1 conversion harness.

Map sensor is on the TB

 

Who's conversion harness? Do you know how to read the pinouts so we can check the harness? Also, do you have the 3 bar checked in Hondata? Or the correct map sensor selected in Hondata for your application?

 

Its a Hondata Harness , spent most of the day checking the pin-outs- They are correct, and the Hondata is set for the stock map sensor

 

What color wires are on the Hondata harness? Do you have a vacuum leak?

 

Colors ? most are just black-there all wrapped in Heat Shinked Nicely.
I dont have any vaccume leeaks,
I was running the AFC hack in OBD0 mode,no problems just running rich, then did the conversion today,
and WHALA- Map cell.

 

Please help my car is my Daily, It must be running by tommorow night.

 

So you confirmed the pinouts on the conversion harness are correct? Is the passage for the map sensor blocked?

 

I just5 Checke d, No its clean.

GOD, this is PISSING ME OFF

 

OK, I was miss informed the code is a 6 dor the Engine coolant temp, will that cause the same symptoms?
