can someone send me a link for the ecu pin layout for a p-72? Or can you tell me what locations for the o2 sensor? Need to get rid of check light.....Thanks

HX_Guy

Here ya go:



The O2 sensor pins are in section A number 5 and 6.
#5 is the Secondary O2 Sensor Heater Control (SO2S HTC).
#6 is the Primary 02 Sensor Heater Control (PO2S HTC)



And also in section D number 7 and 14.
#7 is the signal for the Primary Heated O2 Sensor (PHO2S)
#14 is the signal for the Secondary Heated O2 Sensor (SHO2S)

HX_Guy

Damn..should have known...let me see what I can find...

Ok..heres the OBDI ECU plug:



A6 is the O2S HTC (heater control) - wire will be orange/black
D14 is the O2S signal - wire will be white/red

so another words, on OBD II
the A5 is the same as D14
then the A6 is the same as D7 ?

so I can tap in in either one of those to get an O2 signal right ???

BTW, which is the VTEC solenoid wire on the OBD II, is it A8 ?
thanks

HX_Guy

No the yare not teh same. D7 and D14 are signal pinouts.
A5 and A14 are heater controls...you wont get a signal for that.

If you are trying to hook up an air/fuel ratio gauge...you tap into D7 on OBDII ECUs.

A7 is the VTEC pinout.

Flamenco-T

you mean A8 ?

thanks

HX_Guy

oops..yes A8
