Alright I know this has been discussed before but there has never been a for sure pinout for a 2000 maxima ecu for a vafc-II

This is a pinout for a 2002 after looking it over I believe its different from a 2000.



This is an exact pinout for a 2000 maxima.






for the vafc-II the wires that need to be used are

green (tach) 23 on ecu

black and brown (ground) 48 on ecu

yellow and white (maf) 61 on ecu

red and red (power) 110 on ecu

gray (throttle signal) is the throttle signal the same at tps? would it be 16 or 91 on the ecu?

blue (o2 sensor) I can't find any o2 sensor wires.


Can you look over this and make sure it looks right and can you please fill me in on the throttle signal and the o2 sensor.

also the purple wire on the vafc-II harness is for the knock sensor. gtr-rider told me I dont need to hook it up is that true for a 2000?

 

Don't use the o2 sensor wires, it's a waste of time.

Use the FSM for more accurate representation of said TPS sensors.

 

I dont have a fsm

 

phatg20, use it

 

which section in the fsm should i look in?

 

Ec















.

 

what page?

 

Read it ands see which sensor changes V when the throttle plate is opened.

 

dude forget that its like 500 pages

 

Use some of your more common senses and go to the TPS section.

 

well from what im looking at pin 91 is the tps

 

Thanks for doing a bunch of work for me... I was going to do this if I attempt to install my VAFCII this comming week.

 

you're welcome but I wish over people on this forum would help out as much as im helping others.

 

alright NmexMax I figured everything out.

in the fsm its ec - 114 through ec - 121

tachometer green wire on the vafc-II harness : goes to the green wire with the white stripe. this harness is found behind the cluster and it is the harness that goes to the tach gauge



ground black and brown on the vafc-II harness goes to pin 48 on the ecu.
you tap both brown and black onto ground wire 48. brown goes closest to the ecu and black 1 cm away

maf yellow and white on the vafc-II harness goes to pin 61 on the ecu. you have to intercept pin 61 on the cu harness. in other words cut 61 and then the yellow wire from the vafc-II harness goes closer to the ecu and the white wire goes on the other side.

power red and red on the vafc-II harness goes to pin 110 on the ecu. tap both red onto pin 110 1 cm apart

throttle signal is the gray wire on the vafc-II harness goes to pin 91 on the ecu. tap gray wire onto pin 91

and thats it according to streetz lengend you dont need to hook up the knock senor or the o2 sensor

 

and

tachometer green wire on the vafc-II harness : goes to the green wire with the white stripe. this harness is found behind the cluster and it is the harness that goes to the tach gauge.

 

Quit being lazy and do something yourself

 

BTW: thats you just complained about having to look something up yourself.

 

whatever get out of my thread
