VEMS and EGT

[Billman]

Have some issues lately with my EGT sensor. I see always up and down 0 and them 1125 Celcious. nothing in between. Is the sensor faulty or should i check something else?

[Billman]

? Nobody

What does it do with the sensor disconnected.

[Billman]

Interesting, I didn't check but I suppose it shows only 0??

Can you measure DC voltage ? it changes appr +1mV for +25C - when you heat the tip this should tell you if your probe is dead or you have it in the wrong mode

No, it should show you 1150 or something like that.
Is your sensor 2mm or 6mm one? If it´s 2mm one, then most likely it´s broken, usually from that spot where you fixed it´s position), try to get the sensor out from the manifold/downpipe.
Or, your lucky and there is short circuit inside the connection plug or somwhere on the cable (because at short circuit it shows 0, without connection 1150).

mine shows 0-1125 every 2 seconds. I have the 6mm sensor....

[diesel des]

I think that mine shows 0 when disconnected... will check tomorrow night

i think you should read my post again

[Billman]

yes i had three bad ones

my probe is doing low readings at the moment.

i have a thinker probe./ the wires are the weak spot not the probe tips on those

[Billman]

Yes I think my busted where the cables start after the sensor.

[GazzaG60]

does it touch the bonnet? mine does slightly and over time rubbed through the casing breaking wires

[Billman]

Don't seem to but maye during the engine swap it had to move here and there...maybe it happened that way.
