oil warning light : problem?

[engelborghs]

Just had my 6000 service,
Car runs good, however since 2 days the oil warning light goes on/off under acceleration around 5500 RPM.

Info : oil-sensor was replaced; oil : castrol TMS 10w60

Should I be worried? Anyone else had this problem?
At 700 RPM; oil-pressure between 0 and 3 !!!
Oil level OK

So one problem; being a defective oil-sensor OR a MAJOR problem??

Assume the worst until you know otherwise.

Do not worry if you have oil pressure up to snuff and good oil level, after my car's recent 3rd rebuild at 18500! I was worried about the light. THey said <peninsula> that the sensor was most likely dodgey. It goes like pooh and is fine. Have some faith!?! I have done 900 miles since and all is well...maybe

Hi, this is quite a common problem. Always happens after the oil pressure sender is replaced. Its a very common problem as the ones there in the first place have all failed. It seems like some people have even go through a couple of new ones.

When it happened to me, the oil pressures seemed different to before, and the oil light flickered at 5500-6000rpm and above. Nothing wrong with the car whatsover though. Apart from the oil pressure sender of course!

Hi,

Yes it seems to be a common problem. I also talked to my dealer and he was certain it was yet again a faulty oil pressure sensor. There’s a similar topic in the pistonheads database coming to the same conclusion.
Now when the engine is cold, the oil pressure sensor shows a very high figure at low RPM; more then 40 PSI gradually lowering to 0 when warm.

The dealer told me that it could be an air-bell trapped around the sensor.
So I’m waiting for a new sensor. TVR is supplying a different and hopefully better type.

Thanks and greetings

I've also heard that TVR are supposedly testing a new type of pressure sensor for the speed 6s. About time, as I am on my third, and it went pop after about 200 miles.
