want to know how to adjust s2 tps as i have been told it is different to adjusting s1 tps

mine has the 2 plug tps with 2 harness connectors plugged in but mine is manual :/

could someone please give some detailed post everything about adjusting and the steps please

i know this but need to know if i am correct

top plug

1 volts should be 5v

2 is signal

3 is ground

bottom plug does not matter too me cause my car is manual or does it ???? should i go get another tps with just the one plug?

ok now with multimeter check that your getting 5v supply?

probe the back of harness connector wires 2 been (+) & wires 3 been (-) & check & adjust to 0.45v-0.50v ?

then check with them in same position that you get somewhere close to 4.00v on WOT with ignition in on position?

then do u reset ecu like u have to for old ones?

if somebody could just clear all this up for me would be greatly appreciated

and also just 1 more thing is it true that you can adjust base timing on s2 without a consult to put it into base timing mode?

cause yer i been told that you cant or does the old trick of unplugging the tps work if it does do i just unplugg the top plug? (the only 1 i should have plugged in if its manaul)

or can u trip the consult connector thing into thinking its in base timing mode someone please help me with this?

Adjusting is the same as a series 1, just twist the sensor left to right.

Pin 1 is the power for the TPS

Pin 2 is the TPS opening signal

Pin 3 is the earth

You can check the sensor by reading the resistance of pin 2 and 3, With the accelerator not pressed it should be 0.4V, with it pressed fully it should be 5.0V and half depressed around 2~3V, IF you measure the resistance between pin 1 and pin 2 thats for the TPS SWITCH. Because the sensor is a 2-1 setup. It should have 0 resistance not pressed and then increase when you press it.

The test you said above sounds like reading voltage of the harness which is just probing the 1st terminal and earth it on anything, it should be 5V.

You can check other parts of the harness but you need a diagram of the ECU so you know which terminals to probe etc etc

Also if you unplug any sensor the car just puts itself into a fault mode and will idle at 1500rpm flat.

Yer that's what I sed check 5v supply witch is pin 1 and earth

And so I was right mine sed.

probe the back of harness connector wires 2 been (+) & wires 3 been (-) & check & adjust to 0.45v-0.50v

At the TPS on harness side pin 2 and 3 shouldnt it be O.45v to O.50v not 0.40v like you say and isn't it 4.1v at WOT not 5.Ov ?????

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
