installing d16z6

[wisemansoji]

I put a d16z6 into a 93 sedan civic, and the engine is throwing map sensor codes, o2 sensor codes and a bunch of others. The car was not pre wired so I ran wires for the vtec. Any was the when I use the 1.6L map sensor the cars idle bounces between 1500-2500. I have to use the 1.5L mapsensor which is on th ecars body and the idle is constant but really high.

I found out this is happening becuase theres three more wires the cars bodies harness is missing which are right by the vtec wires,
its missing pinout D21 -SG1 D17 Map( explains why) and D19- VCC1

My question what do the D21 SG1 and D19 VCC1 stand for, and also should I expectg to find other wires that aren't pre wired for installing a d16z6 ina 93 sedan.

All three of those are for you MAP sensor.

What 93 Sedan?, not that it really matters, it shouldn't be missing those wires anyway.

MAP - YEL/RED --|| -- YEL/GRN -- ECU at D19
""" - WHT -------|| -- PNK/WHT -- ECU at D17
""" - GRN/WHT --|| -- GRN/BLU -- ECU at D21

|| indicates the engine bay canon plug.

There's no way they are missing. It's not a special sensor that changed based on model, maybe you're looking at it backwards.

yah its totally missing all those wires, thought it was weird cuz I put this motor ina 94 HB and it had all tose wires but noo vtec wires. noticed today when I looked at a civic with a sohc vtec.

its a base model sedan..........only option it has is tilt sterring wheel and power steering.

 

[wisemansoji]

no I can send u a pic if you want, the top of that plug from the body harness has no wires coming out, it has the vtec wires now , but not those other 3.
Should it have those plugs to be running a 1.5 L. this is weird.

 

[xj0hnx]

Yes, it should have the MAP sensor wires.

did any 5th generation sedan civics come with sohc vtec engine from factory because I'm guess ing the didn't because of the missing wires

del sols si93-95,civic si hatch 92-95 and civic ex 92-95 all came with the sohc vtec(d16z6)

 

[wisemansoji]

so no sedan came with v tec engines.

So is a non vtec civic sedans wireing harness different then a vtec civics harness.

sohc vtec d16y8s came in civic EXs, which had a 4 door and 2 door platform.
