does some one have the diagram of the TRAC system? I specifically need to know the TRAC pump location. I did the tc to e1 diagnostic and got 5 flashes then four flashes from the ABS light and four flashes then three and also 5 then 1 from the trac light . I know the abs light flashing signifies the trac pump but what is the trac flashing?

code 54 for ABS is TRAC pump moter operation frequency excessive, look for leaking fluid and repair. Otherwise check and replace ABS and TRAC ECU.

code 51 for TRAC light is engine and ECT SYSTEM MALFUNCTION Check engine for codes if none. It's no voltage to terminal TR5 of TRAC ECU with engine speed over 500RPM's for more than 1 second, check for short in all the harnesses and ecu connected to malfunction indicator lamp.

I got two engine codes I think one is for the o2 sensor and the othe I think is the o2 sensor/ heater\? but heres the deal these have all been on since I changed the engine. I used the newer intake from the 94 my car is a 93 The plate on the new intake says traction control and on the older one it says TRAC do you think there are any differences in any of the wirings?

Sounds like there is a difference in wiring or ECU's as everything points to a short or malfunction

The TRAC pump is on the drivers side near the master cylinder. Both the TRAC and ABS SYSTEMS monitor the TPS and SubTPS reading from the ECM, so check them for differences from 93 -94

also the airbag light is on. So we have the trac off (always on) check engine , air bag and occasionally the trac light will come on, but the trac light will stay on along with the trac off light. hmmm... anyone have any suggestion? by the way I'll post some pics later in the week so you can finally see another hot first gen gs.

help!!!!!

Also ..Turbo where are you getting your codes from?

turbogs300

factory service manual, is there any other place?

when you say tps do you mean throttle position? This is really driving me nuts
So I should

1. check trac pump for leaks
2. check tr5 terminal for voltage
3. find the paper I wrote the cel engine codes down on

You have to excuse me for being so Unorganized, as I am living out of boxes at someone elses house becasue my builder did not finish as he promised he would before I closed on my house, So if any of you have ever gone through this you know, it just makes doing everyday things more of a pain in the ...

turbogs300

That is correct! Throttle position sensor or the wiring

turbo, whats up with the humping thing anyway

I have an extra tps sensor , so I was thinking of just swaping them out to see if it makes a difference If not I set up a diagnostic with Mcdermott Lexus in east haven CT on friday, It was prety inexpensive.

You don't enjoy humping? I have a 91 Nissan TT300ZX and we always get the honda guys who think they can outrun any car on the planet. So, it's a joke on them

I have an extra idle speed sensor. actually all the sensors on the intake and engine I have duplicates of does it happen to be one of them? or is it somewhere else? Plus I noticed the trans is leaking but when I check the levels it seems alright. My pops told my I have an ocd with this car I told him I have to or the bill for not taking care of it will be much more than if I pay clsoe attention to some things..

It s kind of funny that a couple guys I work with thought that my car was brand new... they actually argued about it one guy swore it was an 03. so of couse I just let them believe it.....why let them know its a 93 right?

do you have any picks of your nissan, turbo?
