! Warning EFI ! Buzz bloody buzz!!!!!

[john purdie]

Ok, so I take my car out on saturday have a great hoon from peterborough to silverstone race circuit (not to a track day i must add!!) but to a ball that I attended that evening, anyway parked car there overnight first time I have ever left it outside overnight, I started it up and fine no problem started to drive it less than 100 yards and boom ! Warning EFI Fault !, all sounded ok no drop or increases in temps etc, sounded fine, drove fine and felt fine but just this bloody buzzing noise.

I spoke to Paul at PPC today and he has said that usually if left outside water can get into car engine etc and cause this or it could be lamba sensors (Or something!) however not to worry if all sounds / drives ok. I am dropping car off to him in the next couple of days to complete a few bits well quite a lot of bits but it is a TVR remember so he can clear it then,

now my questions are:

has anyone else had this is it really nothing worry about or should I be panicking!
Can I stop the buzzing noise or clear the fault myself with the aid of Laptop etc
is there anything I can do to the car (not really technical) to help clear this or assist in helping this

All advice comments well appreciated
Cheers
John

This sort of happend to me last week( read PIXIE~~~~~ DIED, on tuscan station), then on saturday I had the EFI thing , but everything was ok, I think it was because I had got her wet, and had an empty tank, been told to keep an eye on things, but not to worry as TVRs are STRANGE,,(well I say so)

Search on this!!

Happened to mine first time I washed it - press the button to silence it and it goes away....until next time it pours/you wash it!

[john purdie]

Yea Hi Red I agree wiht you there they are strange hows yours now all ok ????


Hi Murph what button cancels it?? it is a 2000 car?

[da_murphster]

Mine is 2000 yr. Press the rh twisty button (right of pod)

This cancels on screen messages...low on fuel, below 2 degrees C, EFI etc etc.

I would only worry if a fault stays on permanently...although search to see if others agree.

+1 for "they all do that sir"

I get it if I splash through a puddle, so I try to avoid them!

Oddly NEVER had it after washing the car or being sat out in the rain (My car lives outside, only under a cover about 1/2 the time)

Well, not had her out since saturday, but after the efi thing, I drove for ages, and it didnt come on again. so fingers crossed,

[john purdie]

once my efi came on I drove back home to pboro from silverstone and again it felt drove etc fine, however it stayed on throughout the whole journey but having said that have not tried to see if it is on today.

so am i right in saying cause mine stayed on instead of going off etc it could be bad news????

[stillgrinning]

I sometimes have efi warnings when it's wet, and almost always when going through a puddle (front near side). So far they have never been "real" and tend to go away on their own. I do however, sometimes get other warnings "stuck" on the screen - No oil pressure, door open, no voltage, low fuel. All have proved to be wrong and all go away, not with a push on the knob, but with a single click left or right.

Spooky...... Still alive to her trying to trick me by blowing up when I think the warning is not real !

[john purdie]

Mmmmm went home last night and my EFI Fault is still on and still buzzing still hoping it not serious

[Sicob]

Mine was out in the rain the other day. This warning flicked on for a few seconds and went away. Do believe it's purely when it gets very wet.

[john purdie]

Hi Sicob,

Yes but is it still on now or did it go off? mine was on for a long journey home and was still coming on last night when I started her up!

Mine goes on stays on a short while then off. It hasn't come on since. Not sure what's best if it stays on, maybe have it looked at?

[john purdie]

ARGHHH!!

Ok am I doing my car damage by still driving it with the "EFI Fault" warning light and buzz? car sounds ok drives ok feels ok and pulls like stink but im a bit concerned now can tget it booked in for a couple of weeks also cant stop driving it!

tried the "KNOB" on the left to clear the buzz but nothin anyone else got any little secrect to help me get rid of it other than taking it to the garage?

cheers

That should be the knob on the right. I'd take it along and get your garage to plug in and look at the diagnostics, only takes a couple of minutes of their time and could save a lot of your money in the long run.

[andyoleary]

Ditto that, get it looked at asap. If it's a persistent error then there is a problem with one of the sensors feeding back info to the ECU or possibly something else more serious. As a rule of thumb, I reckon if the EFI warning doesn't disappear after a couple of resets and a few miles driving (in case it was moisture causing it) then there is something that needs looking at.

Just my tuppence...

Deffo knob on right. Just give it a push.......

[john purdie]

Tuska nope this doesnt work!!!

[Tuska]

It could be a lot of things, but i doubt its actually a genuine problem with the car.
Does the right hand knob scroll the pod screens ok? Coz there is an 8 core ribbon cable that connects from this knob to the main PCB behind the pod. In the past my ribbon cable got snagged (when i was trying to change the pod screen!) and was shorting out. This caused all kinds of malfunctions with the knob itself.
I had to strip the pod down and get the ribbon cable re-soldered.
Anyhow, good luck with it.....

[john purdie]

Hi Tuska,

I checked that this morning actually did not start car just turned on ignition etc, and I went through the screen fine, god I dont know whats going on, as soon as I start car it comes on and I cant get into the screen it just keeps saying "EFI Fault" it wont let me do anything

no worries

cheers
