4Wd Light


Recommended Posts

Hey all

4wd light came on my car last night in traffic, basically no real drive is going to the front wheels

Took it to a workshop i know that has a diagnostic tool and was told it is spitting out, throttle position sensor.

Does anyone have the fault isolation flowchart by any chance or had this happen before??

Any help will be greatly appreciated

Thanks

Nick

TPS at idle should be around 0.4 to 0.5v, any lower or higher iirc can make the ATTESSA light come on.

voltage of tps at idle (shown on power fc control) is 0.41-4V

yes this is a very common problem. It can also be temporarily fixed by taking it off and giving it a clean with contact cleaner and wire drier. But you will need are new one they are a common fault. Mine is playing up and only in cold weather.

Hi, I have had the same problem, It was the left front ABS Sensor, There is one to each wheel. Front sensors mount through the inner guard were the wiring attaches down too the outer hub were the sensor pick up mounts, On the rear the sensor pick up mounts into the diff housing on the inner hub, they run up to the wiring plug above the diff to the floor. From memory they are all inter changeable, Just about bet its one of them, Hope this helps Jamind

    • The springs just lets the valve bleed off pressure/oil and it bypasses the feed gallery and heads back to where the pickup feed is On the LS the oil gets the the bearings...eventually  This vid explains the OEM pump well IRT the pressure release valve and how the bypass works The oil pressure light coming on intamitantly could just be a sticky valve, but, why pull something apart and not put something better in  I believe the low oil pressure light comes on somewhere between 5-10 psi Well will stick a gauge in after the installation to see what difference it makes at hot idle and higher RPM, and by high RPM I mean 6300 RPM.....LOL
    • My bottom end was rebuilt... so I think it's standard? Or refreshed.. standard? I didn't do it - I bought it with a lot of receipts but it has new bearings, new pump and was re-assembled. Apparently I have the standard flow, standard pressure pump. I did notice the oil pressure for a LS at idle is quite low, but not critically bad, I am happy that it's at about 28psi now (that my gauges work/don't leak). I would have probably specced the high pressure one, but I'll admit my ignorance after making my other post, I don't see how the pressure spring changes things. Given the pressure is a resistance to flow... high flow should also = high pressure, and your oil pump specifications should be dictated by how the engine is built (hence the sincere thankyou video man)
    • my first time on the track, just after getting the 32. tyres were 3yr old NT01's, rotors were cactus, pads were street pads. You can see the vibrations when I hit the brakes lol. After this is when I put new BDA rotors, Hi Temp Brake fluid and Intima type 2 pads. Wow what a difference
    • I second the recommendation to use a power bleeder. Pressure on the cap, if you want you can try some vacuum on the bleeder too with a hand pump. Pressure is needed on the cap to make sure that everything only goes one direction instead of potentially getting air sucked into the bleeder. 
    • Which one do you use? Your bottom end is still standard isn't it?
