I Gotta Question

This is the second swap ive done, same engine both times, the only thing is that the harness i used this time had the jumper switch gone so I dont know what i need to jumper together to get the light to blink the code.

So I need to know if a disconnected Oil Pressure sensor or a disconnected O2 sensor would throw the light. Im going to connect them anyways but I want to see if there is another problem before I finish up this swap. TIA

I Gotta Question

ttt that dropped way too fast. come on guys I did a search and didnt tell me about a code from oild pressure sensor.

click the ecu thread in my signature below and that should guide u to your answers

uhh,yeah a disconnected O2 or oil pressure sensor will both throw a CEL.what do you mean the jumper switch is gone?

I Gotta Question

whoever had this harness before i got it had ripped of the wires. I dont even see where they ripped it from. Does anyone have a pinout for those 2 pins that the wires run to? Thanks for the info about the unpluged sensors throwing codes I thought they might but wasnt sure cuz it didnt on my last car.

should be able to find where they go here.
or DL or buy a shop manual and trace the wires on the chassis wiring schematic.

This is the only thing that I could find that was even close. which I dont think they go together.

D4 BRN SCS service check connector

D7 LT BLU TXD/RXD (data link connector)

the brown wire is one of the wires on the service connector you short to get codes.the other wire(D7)i don't think is right....
you need to get a shop manual and trace the chassis wiring schematic to see where they go.simple as that.you should have a shop manual anyway.

yeah I know I had one for my CRX and for my D16Z6, but the one for my Engine i gave (accidently leftin my car) to the impound. So I did this swap by my memory, it really sucked cuz I had all my notes in there including those wires.

I Gotta Question

Do you think that maybe the brown wire just needs a 12volt current going threw it to make the cel blink or what?

I Gotta Question

Well i got to thinkin it may need a ground to go through it instead. So im going to get a circuit tester and see if that brown wire has power or not. I let you guys know how it goes.

EE_Chris

Yes, it needs a ground. When you reach up under the dash and short the 2-pin connector, one of those wires is ground.

The other is as follows:

92-95 Civic: D4
96-98 Civic: C7
99-00 Civic: A10
98-99 Teg: C7
00 Teg: A10

These are from the Helms.

cool I'll go fix the jumper first thing when I get to my car.
