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

 

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)

Damn...you better have meant OBDII 96-98 P-72..or I mgonna be pissed cause I spent all that time researching!

 

thanks man but it is obd 1...........sorry should have been clearer! Help me out again if you can.....appreciate your time

 

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

 

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.

 

you mean A8 ?

thanks

 

oops..yes A8
