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. When adjusting this sensor I found the best TPS voltage was around .385 on the sensor check but this car vary from car to car. i used this on the SUPRA we built for AutObarn.

Q45-------------to -------------r33 series 2

white-------------------------->orange/black ----> signal

black ------------------------->white/blue-----> ground

white/black------------------->black/white------> 12volt power

Thats for a series 2 r33 afm as that what i have.

Its pretty easy to work out, just get ur multimeter, check for power and ground with ignition switched on and the other wire will be signal, i did mine that way, started first go. r33 s1 afm has two signal returns just connect them together, also normally if the loom hasnt been played around with the power wire is always seperate to the signal and ground wires which are isolated with a shield in the loom, make sure you use isolated loom aswell if you are extending as it could cause problems with the signal.

pauls site is good if you dont know the colours etc, thats all you should need really need

    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
