EFI Fault and Oil Pressure of 99 PSI

[Bonedoc]

Drove to work early yesterday morning, very cold and frosty. For the first 10 mins had a repeated EFI fault and the oil pressure reading 99 PSI , once warmed up the fault seemed to go away and the oil pressure reading was normal. Do I have a problem?

Sounds like a potentially iffy oil sensor which is very common. May well also go away with time!

Thanks very much, I see you had a similar problem, did it spontaneously disappear or did the sensor need replacing?
Many thanks

I had an EFI WARNING as well (oil pressure was ok),took it to tvr dealers in exeter and they said it gave this warning because it needed a tune up.They did the tune up and all was ok for a great cost of £40

Oil pressure sensor replaced - along with most of the other sensors since then !

My T350 sits on the drive in all weathers.....
On really cold mornings I regularly get the EFI fault far fractions of a second...
Got used to ignoring it for now and put down to external temperatures...
Along with the 201 degrees temp on startup!!

Car's running like a dream all temps and pressures seem ok after a few miles.
