hey guys i have a question i just wanna double check on something.

i put a gsr motor (obd1) into my civic. im using the old d16y7 obd2 wiring harness on in.

my question is... will i run into any problems if i use obd2 to obd1 jumper harness and a p28?

ive heard yes and no from many people i just wanted to see if anyone knew for sure.

thanks guys.

 

no why would u? just make sure u have an obd2a jumper harness

 

i used an obd2a to obd1 jumper harness. and yeah the iacv is giving me problems. i also had to extend some plugs. when i give it gas it revs up just a little then it cuts off.

 

is it a three wire iac? if so you need to convert it to a two wire and switch the pinouts around.

 

This is a good link for the 3wire-2wire conversion

he did convert it to 2 wire from 3 wire. with the conversion harness and obd1 p28 will he still have to do the crank signal trick?

 

no. the obd1 ecu does not look for the csf sensor

 

CKF.....y0

 

right, obd1 is in the dizzy. we still did that trick and have obd1 to 2 conversion and switch the tps wires runs better but still feels like hes towing a trailer at 5k rpm and it seems maxed out and loud. and cel is on for manufacture igintion misfire....? any suggestions

 

No CKF sensor isn't in the distributor. It isn't needed for the OBD1 ecu. You are thinking the CKP sensor that is in the distributor.

What code is on? Two wire switch on the TPS? why

 

yeah thats what i meant. original motor was a y7 with the TB that faces up and the butterfly opens backwards. dude put a gsr motr in. the engine thinks its wot when its shut. we switched it and it runs alot smoother but still feels like towing a train and maxes out at 5k rpm. il have him ina few minutes post the codes

 

alright so i got a few more codes from the last time we had it checked.

p1382 misfire/ignition

p0500 speed sensor

p0135 o2

p0141 o2

im gonna change the tb tomorrow morning see if the difference in tps sensors.

 

Splitting hairs??

 

Nope. Just clarifying for others out there on the most missed labeled sensor ever.
