P0460 Fuel Level Sensor Circuit Malfunction


P1687 Metering Oil Pump Stepping Motor Circuit Malfunction
P1687 Motorised throttle(stop learn)
P1687 Throttle driven [signal implausible]

take your pick

Welcome to FF!

Dont worry too much about P0460 i always get it and it doesnt cause a problem...
P1687 is throttle body related id suggest doing a 'Throttle Relearn' for starters and see if it solves it. make sure you have good battery voltage before you start its no good trying it with a low battery as it will most probably fail.

1) switch ignition on (DONT START) for one minute
2) switch ignition off one minute
3) start car (DONT TOUCH THROTTLE AT ALL) and let idle until cooling fan cuts in (10-15mins)
4) switch off
5) repeat step 1
6) repeat step 2

Thanks, I'll give it a go

I have two error codes on my fiat punto 00850 and P0505? can any one help me out

just to remind you: all codes up to P999 are standardised for all manufactures and can be easily found on the internet.
For codes from P1000 onward you need the manufacturer-specific info for their codes.
