Hey guys, me again...
i'm SO close to getting my car on the road. It's a 90 crx with a B18C type R motor in it. I got the obd0-1 conversion going on with a p28 ecu chipped for the engine.

Now when i drive my car, or should i say when i TRIED driving my car, it goes into first gear fine at low rpm, and when i give it gas and rpms go passed 1500 it starts to jerk like CRAZY. like when you let go of the clutch way too fast. Thing is, is that the clutch is all the way up. Mind you it does seem like it engages way too high (i have a cable to hydro conversion from innovative)

I checked the engine code for the car thanks to the conversion piece i got from rywire it was easy to get it to display the code.

I BELIEVE that the codes are 4, 46 and 6. I'll indicate the morse code that it gives me

__ _ _ . . . .

__ _ _ . . . . (space) . . . . . .

Before I even start it, it gives me the second code i've put up. Then when i crank it and sometimes it cranks and stays on, and sometimes it dies shortly after. But when it does stay on, and i check the code again, it gives me both of those.

Can anyone help me? if they really are 4 and 46, it's the crankshaft positioning sensor and right fuel metering. I have no idea what either of them are.

Thanks in advance

-Jon

You paid for a conversion harness to read code? Didn't you know there is a 2 plug on the passenger side that when you connect the 2 together (jam a wire in the holes) it makes the engine light flash the code?

Just like the obd1 cars.

Code 4 should prevent you from revving pass 3500 rpm (limp mode) as it's crank position, a fairly important sensor.

Look up what the codes are, then check the wiring for those codes.

 

oh no... i didn't pay for it JUST to read the codes... the conversion harness was for obd0-obd1 so i needed it.. it just so happens that rywire also wired 2 extra wires on there to do the check engine codes...

know of any way to fix the crankshaft positioning sensor?? i DID change the timing belt but i made sure that everything was at top dead center....

 

Kind of off topic but in the instructions to a jumper harness I purchased not too long ago it said you jump the wires on the timing plug on the driver side of the engine bay to check the obd1 ecu codes. I could be wrong but that's what it said
