Egt Lamp Keeps Coming On!

[wind1]

My EGT lamp keeps coming on and flashing and I don't know why, I have looked through the R32 service manual and it didn't help me very much.

Any Ideas?

Are you running a PowerFC ecu?

If so the FC uses the EGT warning lamp for knock.

Mine used to flash if i was forced to use 95 ron.

I'm pretty sure that it is just the standard ecu, the light is inconsistent flashes too.

Maybe if the car had a different ecu in it when it came from japan and had been removed incorrectly, could this be a problem?

[CEF11E]

this can also happen when the rom is not seated in the cradle in the stock ECU (only if you have a remapped ecu)

[Beer Baron]

also happens if your cat temp sensor has been removed but the dude that did it has left part of the wiring where it can contact and earth out on the car body. this causes the warning light to come on.

Just had a look at the cat and under the seat and it all looks to be connected OK. Haven't looked in the ECU yet to see if anything looks loose. The temp sensor looks pretty rusty though don't know if this would affect it.

[InterCooL]

does it do it continually or just when you give it some stick?

my temp sensor would go off when i gave it a hard boot, came from a restrictive exhaust. clogged cats can cause it

It's pretty much constantly going on and off, but in inconsistent flashes.

I might pull out the cat and have a look it might be that.

Just an opinion but usually means cat is blocked by melting or broken pieces inside blocking it.

I had a similar issue, & discovered it was my ecu. After replacing it(socketed ecu) my car was back to normal. try a different ecu...Hope that helps...

I just looked at my cat and it looks fine, but only from the front side haven't looked in the other end. Could the muffler block the exhaust at all?

Very true

[wind1]

I was just reading through the service manual and the EGT lamp is used in conjunction with the ECCS self diagnosis system so what it's flashing is actually a fault code from the ECU. I pulled the ECU out and put it into test and sure enough the lights both flash 55 for normal systems.

I just need to go for a drive now and see what the code is while running.

Explains why it was so inconsistent.

slide your hand under the car, where the EGT probe goes into the cat, grab ahold of the cable, give it a gentle pull TOWARDS the cat (So that you'd be pulling cable from the car towards the cat)

You might find that it's cut, like mine is.
