ive been told by my mechanic that if an 02 fuel fails on my au xr6 a light will indicate on the dash.is this correct.thanks all

0'2 censor failure, resulting in illuminated dash light? That was your question I think.
If so, I don't think so.
This might show on a diagnostic fault scan, but never heard of that censor having a dash indicator. Why would such an insignificant part need to warn you of failure?

No
Your mechanic is misled.

Seems to be a lot of those getting around.
I'm amazed on a weekly basis of some of the irrational things said by mechanics. People that should know one end of a car from the other, but whom seem to have no flipping idea!

im just curious if this sensor should be ever checked to make sure its operating correctly.am i right

I think you may - called the fuel gauge. When it uses more than normal, may be the O2 sensor..

And you are right, these people should be able to tell you whats what or if in doubt - say nothing.

The rule of thumb is change them every 100,000, along with the plugs. Cheap insurance really

For the sake of $50 just change it bloke

david lee · 12-05-2015, 08:10 PM

this is the same mechanic who says useing 19.25 litres per 100ks city driving is normal for an xr6 tickford which to me is not right

is he talking about the check engine light coming on due to an emissions fault ?

On your exhaust headers, after the heat shield but before your cat.

Should be super duper easy to see and change as you don't have an LP Gas Converter (i'm deducing this because if you did have Gas you'd be fine with 19L/100k)

I think perhaps it only takes one spanner and one plug and that's it?

Blocked fuel pressure regulator can also cause high fuel consumption.
These are located on the back end of the fuel rail (inlet manifold), at the firewall.
Pull the vacuum line, remove the large "C" clip, remove the guts & check the gauze filter.

I hate mechanics that "guess'.
If your vehicle is not running normally, then there's a reason for this. Taking the "logical deduction" approach should quickly lead you to a problem part.
Ie: if a tyre is flat, it's a waste of time changing wiper blades!!!

I will add though that it's not unreasonable for an XR6 to use upto 20L/100km doing short drives.
Falcons are renowned for being fuel guzzlers. Try using the economy setting (auto trans) or just go easy on the go pedal for a week.
My stock AU2 sits on about 16L/100 around town & around 9 - 11 on the highway. It is high but the point has been proven.

its good to hear all this information.this is a short drive xr6 but has the get up and GO behind it.maybe a good highway drive wouldnt go astray
