EFi Fault!!! Help!!!

[robsrollers]

Recently I had the horror of the EFI warning fault spring up on the dash, I have taken to my reliable TVR garage in Southampton to magic it better, but sadly he is unable to cure it. He seems to think it a speedo fault and told me to head for Racing Green TVR. (as they are local to me)

To all the people in the know, is this the only solution and has anyone else suffered with the same problem? If so do you know what was done and roughly a cost to fix?

The problem only started to when I drove through a bumpy field..i'm aware that the tuscan doesn't double up as a 4x4...but I was directed to park in the field at a local show!!

Thanks

visit www.mytuscan.co.uk for a list of the codes.

If it is the speedo then a simple replacement

Not an expert by any means, but why would the speedo throw up an EFI fault? The only time I get an EFI fault is if I'm running the engine with the airbox out and thus the sensor on the airbox pulled out. Might be worth checking this? Could be as simple as a loose/poor connection!

Worth a try!

I get the fault if the car has been out in the rain or has been washed, not a big venturer under the bonnet so others will tell you what gets wet...

Only time I got the EFI fault was when the battery was jump started. Quick trip to Dulfords and got the ECU reset all has been well since.

I used to get that fault but again, only on rainy days or when it had just been washed.

Mine was giving fault code L, I was told cleaning the sensor on the back axle fixed it.

And since you have been rallycross-ing...

I had that one too. It would try and stall the engine and then the error message would pop up.

Turned out the throttle bodies needed a slight adjustment.

Thanks guys!

All your posts have been helpful, I will have a go at a few of the suggestions and keep my fingers crossed!!

How I love owning a TVR, life would be boring without these curveballs they throw at you!!

My EFI faults have always been coil pack issues - again easily fixed...

good luck!

BEWARE WHEN PARKING IN FIELDS,, the cats can set fire to long or dry grass,

I burnt 2 marks in our short lawn with the Cerby a few years ago (took me a while to realise why the lawn had 2 dead patches on it)
