Exhaust Temp Gauge Not Working R34 Gtr

[sr20dettttt]

Hi guys,

My exh-temp is not working on my mfd. It does not display a value.

This happened when I had to take my engine out to replace welch plugs... placed everything back into the car.. everything works perfectly except the exh-temp doesnt show.

I've checked if the sensor is connected, which it is.

What do you guys think? I will take it back to the mechanic, but if its an easy fix, wouldnt mind just fixing it up.

Thanks in advance

Take engine out for welsh plugs?

[sr20dettttt]

yeh.. a few of them are leaking, replace one, then replace all i suppose..

replace sensor? it was working prior to taking the engine out.. are they fragile or something?

[Ben C34]

What welsh plugs did the engine come out for?

Take engine out for welsh plugs?

Yep....

Can you get to the one at the back of the block and head while the engines fitted?

Cant get to the one at the back of the head even with the gearbox removed.

If you know a way kindly enlighten me.

Ah yeah.. I'd fully chemical weld that shitt.

Engines goanna need to come out for a real reason soon enough.

Unplug, replug sensor.

If no go, replacing it would be a good start.

Also make sure all your chassis grounds are all on......just in case.....

chassis grounds... wouldn't know where they are.. could be everywhere lol..

Try resetting you mfd, let the car warm up first. Turn off engine, push and hold joystick in, turn car on, let go once gtr logo is displayed, straight away push joystick 5 times, should go into diagnostic mode, wait till all sensors turn green, exh temp takes awhile if engine was cold, drive around the block to get all sensors up, then turn off engine and start back up, exh temp should display.
