Hello Gang

I am new to this site however now deciding to take part in the forums to hi!!!!!! You all have been huge help in the past with several things.

So... I just swaped a B17A1 in my 92 Honda civic DX hatch.... Its running with a P06 chipped ECU tested and working great.

Issue is its not running correctly kinda ruff however timing is great! ... I have 3 plugs all 3 wire.. unsure where they go right near he intake where the throttle body is.... tried to search google for some help but its a bit beyond me... Now these 3 plugs are near the intake.. I would assume TPS MAP and ?? I have been swapping with them map to TPS and 1 would make the engine rev up till like 2 grand.... The others no response..

I am almost sure its in the wiring and hoping someone can help.. The rest of the engine bay I am 100 percent sure is wired and all attached correctly..

HELP!! I am learning but fairly smart...

Wish I could attach pictures I am sure that's connected as well.

What are the colors of the wires on those three plugs?

Also, for posting pictures, upload them to a site such as www.imgur.com and then post the "forum link".

If its a '92, it will have a 3 wire MAP sensor in the body harness, and depending on the wiring harness your using, there can also be a 3 wire MAP sensor in that harness if its not the original '92.

The 92 Gsr has the map sensor on the firewall if I remember correctly but I'm not sure if it is tied into the engine harness, so the plug on there should be tps. Map is white, yellow green, and green blue.

yes you are right! its an external map sensor I have two of them! original one from my 92 civic and a gsr one.. tried both not much difference.

3 plugs total all three wire combinations are:
-yellow/green white/green green/blue (from body of car)
-yellow/blue red/black green/blue (from engine harness)
-yellow/red green/white white/yellow (from engine harness)

You may have use the one from the engine harness and tie it back to computer... Have you tried putting the ignition on and doing a tps voltage sweep?

DanTheMan83

No Tps sweep yet... is that just checking with the OHM meter and making sure its under .45 volts?

halfakneegrow

.5 volts closed and between 4.5-5.00 at wot (wide open throttle) that will also let you know which plug is giving you voltage to the sensor

Try and find a civic engine harness it will make your life easier
