We finally got my car fired up last night. But it is throwing a Crank Position Sensor code (CEL Code 4)


Info:
Built B16 swapped into a 1989 Civic DX
Still OBD0 with a Pr3 ecu
DPFI>MPFI conversion

We also threw a IAT, and Vtec Solenoid, and TPS code...but thats only because we havent hooked these up yet. (Hasport Sub harness) We were just making sure it would crank.

So my first question is...would these three codes be linked to the CPS code being thrown?

And second...how would i go about correcting the CPS code.

Thanks guys...

Bump?

Any Info would be greatly appreciated...

i think the cps is in the dizzy so u might need one. i have a spare b16 obd0 dizzy if u need it lmk.

KraziCivicSi

Are you sure? Im just asking because some1 else told me that it was in the motor itself (by the Crank pulley?)

Lol...i would hate to have to get another dizzy...i just got this one...this is the second one...

crx_si-r

i think the newer GSR's have the cps near the crank pulley. i thought the b16'a had it in the dizzy?

KraziCivicSi

This isnt an ordinary b16a...the block is b16a3 (from the USDM del sol

i thought only the d series had it in the dizzy...i searched for about an hour and nowhere could i find where it is exactly

No, the CPS is not located near the pulley.

The CYP (Cylinder Position), CKP (Crank Position) and TDC (Top Dead Center) sensors are all located in your distributor. The sensor that is located near the pully is for OBD2 cars and is the CKF (Crank Fluctuation Sensor).

Do a continuity check on all the sensors between the distributor and the ECU.

correct just buy a new dizzy off ebay and then reset your ecu

I've never seen any of the CYL, TDC, or CKP sensors go bad. I have seen several CEL's because they were wired incorrectly.

Same here.


How did you wire it at the ecu? When i first did my mpfi swap and connected the two wires at b10 and b12 for the CPS i didn't depin b12 and repin the new wire. I tried to splice into it and it threw code 4. Well i depined b12 and repined the new wire and the code went away.

Thats what happen. Went back and repined the new wire in and everything is all gravy. Thanks guys!

Great

My 91 hatch is also throwing code 4. It also won't go above a certain rpm, is this because of the code. I have an obd0 dizzy and an obd1 ecu. Do I need both to be the same obd? And of course it's a B16. Thanks in advance for the help.

Slurp56

Yes.

OBD0 works with OBD0 Dizzy only.

OBD1 and OBD2 are interchangeable but they have different plugs on the dizzy.

I'm surprised your car even runs.

91_Civic_Hatch

That's what everyone says, they're surprised it starts. Thanks for the info Slurp . Another quick question, can I put obd0 plugs on an obd1 dizzy?

Slurp56

Sure, use a small screwdriver to depin the plug. The actual pins should be the same size, so its just a matter of getting them in the correct order in the plug itself.
