EFI Fault

[dvpeace]

I have an EFI Fault or sometimes 0 volts. Very odd, car goes fine, alert clears in an out when you are driving.

Any suggestions?

Yep - keep driving

Sounds silly I know, but if I wash my car, or there's a heavy downpour, I get the EFI for a few minutes, and occasionally the 0 volts bleeps for a few minutes.

It's always gone away pretty quickly though!

As for the 0 volts, if you actually mean .0 volts, this can come up when you nudge the right hand pod rotary knob, and it's not seating properly. When you rotate this you can feel the knob gently clicking into place, sometimes you can knock this without realising, and the .0 volts comes up, just turn the knob a touch, and it should clear.

I must have done that because I now have the EFI fault back, I'm sure is another corroded wire.... I've had a spate of these recently.

I thought it was the rain, but has not gone away!

Still driving though...

A persistant EFi warning which will not go away with the POD knob will mean a trip to your dealer unfortunatly they will plug into the lap top and see whats occuring
P.S Low volts/oil pressures/fault codes ect i tend to ignore if they disappear with in SECONDS of startup
it`s a TVR, mine has a mind of it`s own at times

I also get the EFI Fault warning quite a lot. My oil pressure is reading from 8psi (idle) to 38psi (hooning), and recently my water temp has been getting to 110 while in traffic.

The dealers had a quick look about 10 days ago and suggested the oil pressure and water temp sensors were knackered.

I also get stuttering under acceleration sometimes so its going back for a proper look this week.

Just to clarify, I advised checking the r/h pod knob setting purely in an attempt to clear the .0 volt reading, I did not mention this as a means to correct the EFI fault.

Thanks everyone. The dealer did check the car and cleared the EFI warning but it came back, my guess is it's a loose connection. I've had a spate of silly electrical issues caused by corrosion.

Mine turned out to be a dodgy oxygen sensor. The dealer replaced it and since then the car has felt a lot better. It no longer stutters under acceleration and it seems a lot smoother through the revs.

Very happy with that

Cheers,
