Need 1998 Civic Coupe EX Automatic P2P ECU Pinouts! i just notice there are 4 plugs to this auto ecu. and i got a scan tool and code came up as P1337. which is the Crank Fluctuation Sensor..i think.

i read this and i wanna try it out. but pinout for those manual ECU are different. (they have 3 plugs for both OBD2 A/B)

is there anyone with a diagram for the Auto P2P ECU pinouts? much help is appreciated.

ok so i used this.

to locate the wires im looking for..the link above said to use these wires

CKFP - C1 blue/red
bind to
CYPP - C4 yellow

then

CKFM - C11 white/red
bind to
CYPM - C14 black

(C1, C4, C11 & C14 colors matched up perfectly on the "C" plug on the Auto P2P ecu)

i bind the 4 wires into a pair and it eliminated the "P1337" and later came "P1382"

"P1382 CYP Sensor A No Signal"

what did i do to get no signal to CYP Sensor?

so i decided to put all wires back to singles and i guess imma try to fix this by replacing the sensor? any instruction to changing our the sensor?

I'll have to cross compare the ecu pinouts for the 4-plug auto EX ecu vs. the 3 plug EX ecu and see if there's any differences in wiring for the CKF sensor. Usually the 4th plug is mainly used for the Auto tranny, and the rest of the plugs remain the same (use the same pinouts for engine functions and sensors).

For now, I say try performing the CKF trick as explained on my tech site and see if that eliminates your CKF code as well as the CYP code; cuz you can always undo the wiring for this trick if it doesn't work...
