French term or phrase:top roue
Here's the full phrase:
Absence de détection apport carburant sur perte d'un top roue
In this case would 'top roue' simply be the 'upper float'?
TIA Chris.
Thank you for your words of wisdom. This is the 4th document that I'm working on, part of which has already been done, so I have to pick out bits that are not complete, often repetitive with only slight changes in the process command line. It's all good fun.
Due to loss of wheel sensor, no detection to add petrol. i.e. the onboard processor does not know how many miles have been done and that you are running out of petrol. I've seen the light, no the moon.
Thanks for putting up with my ramblings.
Chris.
We're certainly on with the fuel tank 'bouchon de carburant' 'ouverture ouvert' etc. So all about how much fuel left in tank and sending info to driver. 'top roue' obvously tells the onboard processor how many miles the car has done, but not how much fuel has been put in, which is one of the parameters, the other one being the float that tells them fuel has been put in. Ho hum. I think I'm getting there slooowly.
un capteur de top roue arrière seems OK to me; that's a sensor (probably the ABS sensor) which detects impulses (they are our "top") from the wheel as it rotates and, in addition to its ABS functions, derives the rotational speed of the wheel and from that the road speed.

Presumable: Disconnect a rear top wheel sensor!!!!!!!!!
The mind begins to boggle - tea time me thinks, or at least an apéro
It's not a sensor on "top of the wheel" — 'top' in French is a faux ami, it just means a fixed timing reference point (in Game shows, when the presenter says "Start the clock!", it is « Top chrono ! »)
And I'm not sure that this 'apport' is about putting fuel in the tank — only you can tell, of course, from your wider context, but I had assumed this was about metering the fuel in the injection system; clearly one of the parameters to be taken into account would be road speed, i.e. inferred from wheel rotational speed.
Or maybe it's something to do with "how many miles you have left in your tank" — my car makes an intelligent estimate of miles remaining, which is constantly updated based on your rolling average fuel consumption.
Am I missing something here? How does a sensor on top of the road wheel recognise fuel being put in the tank?
Perhaps its time for me to put something in my tank!!
Well, at least we do now know for sure it is indeed referring to the road wheels.
I have come across 'top' a lot used (rather in the way it is in game shows!) to mean a synchronizing mark, etc. — here, I feel sure it would be some sort of pulse (probably magnetically-induced).
I've just come across another example: Don't know f this tells us much?
Vérifier que dans le cas d'un apport de carburant avec stratégie d'apport par vitesse véhicule,
la détection d'un apport de carburant est toujours possible en cas de perte de l'un des tops roue AR.
La détection d'apport de carburant n'est plus possible sur perte des 2 capteurs de top roues.
Ce test est à réaliser sur véhicule uniquement.
Tony M has inspired me to look on the web and I've found a Toyota document that seems to support his suggestion as a possibility. It might be worth a look, especially page 5. http://www.autoshop101.com/forms/h36.pdf
My diesel-powered boat has two devices with a wheel spinning inside each measuring the flow to the engine and the excess returning to the tank. I agree with Tony that the 'top' is a pulse from such a device.
No, I think this 'top roue' is in the fuel tank. Later on I have 'flotteur', fair enough. Perhaps top roue is in fact a roller on the float that operates a contact?
I think the 'top' is a timing pulse, dervived apparently from the actual wheel; presumably, this is what enables the ECU to calculate the fuel consumption (or is this about injection metering?).
