Alright.. Emissions has hit me again, and I'm screwed. Here's the back round, I have a 97 Civic Coupe Dx.. obd2a, I swaped a 94 b18b1 LS obd1 in to the coupe.. right now I'm runing an obd1 ecu with a conversion harness. In order for me to pass emmisions, due to the new law, they plug a scaner into the obd2 port and read the ecu. Since I'm running a obd1 ecu I can't pass. My Question is what can I do to get it to pass.. if I plug in the stock obd2 ecu I through a couple codes. One of wich is my Crank Position Sensor.. what do I have to do to install one if possible. I've heard something about swithcing Oil Pumps with an obd2 oil pump, and that will have the obd2 CPS which will get rid of the code.. If so how do I go about doing so.. the rest I can figure out.. Any ideas and proven solutions would be helpfull.. THANKS!!!

 

any one?

 

that Crank Position sensor is in the Dist. if im not mistakin. It reads if your timing is wrong, you cant just add the sensor( i dont think). When you throw the code usually you have to change th dist. but this isnt your case so im guessing get a chipped ECU

i think im thinking of the CYP sensor code. But maybe the ECU thing might help. We dont have emissions here so i wouldnt know any tricks to get around it.

 

you can not pass you put an older engine in a newer car, you can only get around it if you put a newer engine in an older car

 

well basically if i run obd2 ecu ill pass ... nut i need to get rid of all the check engine codes!! all i need to know is if its possible to change or add a cps

 

you can put an obd1 motor into an obd2 car as long as you put all the obd2 sensors on the motor. You'll need to get an obd2 oil pump and really it has nothing to do with the actual pump itself, the obd1 pump doesnt have the threads to mount up the crank angle sensor and thats the only reason why you need to switch. If you've ever changed a timing belt you're doing pretty much the same thing in order to get to the oil pump and just putting the sensor on. Pretty simple. I have both parts if you need it. 80 shipped

 

how about you just de-pin the the wires that run to the sensor? Meaning take that **** out from the ECU.

It would still throw a code, taking the wires out of the ECU doesn't change it's code.

 

Slo97coupe have you resolved this problem yet ?
I would like to know also.

 

OBD1 cars have crank position sensors but they are in the distibutor maybe theres a way to wire it up so that the OBD2 ecu reads it from the distributor?

not yet!!...

can some one clarify where the ckp sensor is located!!

 

the CKP is in the distributor
the CKF (crankshaft fluctuation senor) is near the oil pump.

ppl get this mixed up alll the time. like jdm motors do not have the CKF

 

so my ls has ckf!! but doesnt have ckp??
how can i fix that

 

People pm me atleast once every month asking how to do this so here it is,

All you need to do is wire it to the ckp from the dist. you can just tap the ckf wires to the ckp wires at the ecu, you should have A wht/red wire from the ckf that needs to connect to the wht. wire from the ckp and the ckf blu/org wire goes to the blu. wire from the ckp...your just stealing the signal from the ckp sensor in the dist. you shouldn't need to cut any wires at the ecu just connect them together with A wire connector or solder them. It will eliminate any codes and it will not have any performance issues.

 

i may be wrong but the ckf just looks for speed variations in the crankshaft, as a way to check for misfires

 

It's A mag pick up just like the ckp
