[arnaud_mr2]

hi,

who have the wiring for put Q45 tps sensor on 3sgte please?

I have 6 wire on the Q45 and 4 on 3sgte

on Q45:
RED
White
Black

and

Red
Black/yellow
green


on the 3sgte TPS i have only 4 wire

Purple for IDL
White for VTA
Bronw for Ground
red /blue for VC

have you wiring for put this sensor on my 3sgte?

[arnaud_mr2]

i have find this:
FOR NISSANA TPS
Red: Power
white: Signal
black: Ground

idle plug
green: Idle signal
black/white: Ground
red: Not used

i think this:


toyota white goes to nissan tps white
toyota blue/red goes to nissan tps red
toyata brown goes to nissan tps black and nissan idle black/white
toyota purple goes to nissan idle green


please confirm me this tomorow i put my nissan sensor

You can work it out with an ohm-meter.

Arnoud,I asked a similar question,
Bob hatton was very helpfull,
i have included the gist here,
but,some q45s depending on age have different coloured wiring.

This should help.

The Nissan TPS uses two 3 wire connectors on it. One is on a short section of harness about 6 inches long and handles the actual throttle position signal and the other made to the body of the sensor is for the idle validation circuit which you also need or you get a code (51 I believe). With the sensor standing up, with the mounting tabs on the right side and the TPS wiring harness coming out of the bottom while your looking at it the top 2 pins in the connector made in the sensor body are your idle validation pins so disregard the bottom pin. Your TPS wiring harness that comes from the bottom of the sensor will terminate at a 3 prong plug and have red, white, and black wires in it. The wires colors correspond with these functions:

Red is the 5 volt input wire

White is the TPS signal wire

Black is the sensor return wire

With the connector lock up the white wire will be in the center, the red wire should be on the left, and the black wire should be on the right. My car is an 88 so I can give wire colors for an 88 Toyota Supra.

Brown is the E2 wire for the sensor return

Blue with a red stripe is the Vc wire for a 5 volt supply

Yellow with a blue stripe is your IDL wire for Idle validation

White with a red stripe is your VTA or throttle position signal

You take your brown E2 wire and branch it into 2 seperate leads. One will go to the idle validation switch and one will go to the TPS harness connector. You can put the one E2 wire(brown) on either the top or second post of the idle validation connector( the one made on the sensor body itself) and the IDL ( yellow with the blue stripe) will go to the other. Then the other E2 wire(brown) will go to the black wire in the Nissan TPS harness, VTA wire(white with red stripe) will go to the white wire in the Nissan TPS harness connector, and the Vc wire(blue with red stripe) with go to the red wire in the Nissan TPS harness connector.

When adjusting this sensor I found the best TPS voltage was around .385 on the sensor check of my S-AFC. This will trigger the idle validation at 3 to 4% throttle which takes alittle getting used to at the pits at the track or light cruise loads but it turned out the code and gets a 100% throttle reading on the afc. I hope this helps any questions I can answer feel free to ask.
