Hey guys. I just installed a 99 b16a2 into a friend's 98 civic ex coupe. I used the ex harness but I had to unused plugs. One was by the fuel injector wires which I figured out was for the emissions thing bolted to the fuel rail. Now I have a three wire plug hanging right above the oil filter.

Now I check the CEL and of course it threw the Crank angle sensor no input code. Naturally, Nothing was plugged into it. Now am I supposed to extend two wires from the three wire plug for the two wire CKF? if so, which colored ones? We're using the ecu that came with the swap and I doubt he'd want to do the whole OBD2-0bd1 harness with a p28...

Also, I took it for a spin and if I was easy on it, it accelerated with no problem. If I mashed it, it bogged down and didn't want to move. I was thinking map sensor but could this fix that too?

I know there's also a bypass trick but that's if nothing else will work.

Thanks.

Crank angle and fluctuation sensors are different. What specific codes are thrown?

 

I was in a hurry so I didn't get the exact number for the code but I got the code for Crank position sensor no input.

and Hondapartshero, so that IS the right plug?

 

CKP is code 4.

 

well I wont have the OBD2 tester until I fix this and see if it goes away.

Without knowing the actual code, it's just guesswork. Jump the service connector to pull the code ---> see CEL sticky at the top.

 

Yeah the CKF (by the crank) and CPS (in the distributor) are two different things. Pull the code and post.

as said, post the code.

 

its showing codes
14- IACV
54- crank fluctuation sensor
70- ??

 

Theres no reason to bypass it if it's already there. Just repin it

 

Well now I'm confused. do I need to wire up the one behind the crank pulley or is it something that needs done to the distributor??

 

Code 70 is an automatic transmission malfunction code. What ECU do you have?

Reset the ECU to see whether all three codes repeat. The ECU reset is done by removing the 7.5A hood Back Up fuse for at least 3 minutes.

 

P2E ECU

 

Is this^ ECU for an automatic transmission? Does your buddy have an automatic transmission linked to his B16a2?

Did you reset the ECU? If so, what happened?

 

i pulled the negative cable off the batter AND the back up fuse and all three came back

 

He ordered this full swap from ebay so I'm not sure about if the ECU is for an auto. No, it's definitely a manual transmission and so was his old D16y8.

 

wait, I just checked an ecu list and this came up:
P2E OBD2 no VTEC 1996-1998 Honda Civic DX

did he get the wrong ecu??

 

P2T OBD2b VTEC yes 1999-2000 Honda Civic Si

I believe this one's the one it's supposed to be

 

Yes, wrong ECU for the swap. That's the cause of code 14 and 70.

When he gets the right ECU, he'll also need an OBD2a-OBD2b conversion harness.

Code 54 may just be a wire problem or the CKF is unplugged. You need to remove the crank pulley to check it.

 

get a jumper and run a obd1 computer, problem solved.

 

That was my other question, I couldn't find a plug to run to the cfk.

And so either way I have to run a conversion harness??

 

I wouldn't have to run a different dizzy or injectors for the chipped OBD1 ecu? I've never had to use a conversion harness before.

why are EK's so damn annoying.... I wanna get back to my del Sol.... >_<
