Error Code 35 help

[silentstu]

i have just checked my error codes and got error code 35 its turbocharging pressure sensor signal (pim)

Car is a Rev 2 running a HKS fcd and running 0.91bar of boost
tvsv is unplugged

i cleared the code and then started the car up (didnt drive it) and
the code came stright back

Whats broken then and how do i go about sorting it ???

Thanks

Hmmm, I wonder if the MAP sensor has been unplugged (cheap way of disabling the boost cut, not saying you did it though!) and that's throwing the fault up?

[silentstu]

ahhh ok what am i looking for there ?

[Slarty]

Well the easiest way (assuming that you are indeed talking about a rev1/2) is to see if the stock in dash boost gauge is working. If it's not, then there may well be an issue with the MAP sensor (i.e. it's unplugged)as that's all it's used for on a rev1/2.

If it's working, then that means the MAP sensor is at least plugged in. It could still be faulty though I guess...?

[silentstu]

yeah the std boost gauge works and always has since ive had the car car is deffo a Rev 2.

Try unplugging the MAP sensor then, just to see if it stops the error being thrown up. It's mounted on the rear bulkhead (the one between the boot and the engine compartment), a grey box about 2 inches or so square with a hose and small wiring plug going to it?

Ok I'll give that a try when I got time to play with car again cheers

Presuming the label on them is the same, it'll say SENSOR ASSY, TURBO PRESSURE on it

According to Toyota Manual

Fault
open or short circuit in the turbocharging pressure sensor signal (PIM)

Trouble area:
Turbocharger pressure sensor circuit
Turbocharging pressure sensor
ECU

It then sends you to this page

cool where did u get the toyota manual ?

[silentstu]

cleared the code unplugged map sensor and code came up again

think ill need to do the voltage test on the plug to it see if the fault is before the sensor or if its the sensor itself

i had a similar issue. my thinking went along the lines of: if the sensor is unplugged it cant be that causing the problem. That leaves sensor circuit and ECU. As i hadnt modified the wiring and there werent ant snags or disconnects i concluded my ECU was fubared. however i stopped short of changing the ECU to prove my theory correct. not stating this as fact, just my experience.

That sounds great except the TPS has a switch in it that engages at idle, and the ECU will flag an error if it doesn't see this. To be honest, unplugging a sensor will work the same as a sensor failing, so the ECU will report it as that. Unplugging stuff is not the answer!

i unplugged it due a suggestion here, Think ill have to check the wiring where the fcd is but we solderd the wires up so shouldnt have a problem
gonna check it with a multi meter when i get hold of one.
