I have this error code:
"P1170 - Mixture ratio [Minimum lean fuel]" on my punto 1,2 8v 2001.
The engine yellow light is on.
To be spark plugs, lambda sensor or else ...
Thanks!
codes which start with 1 are manufactuer specific so generic readers are no good as these only read EOBD errors (some 'snap on' [mt2500 etc] do bit more but not a great deal)
The Check engine light means an O2 sensor problem.
Anyone who has taken this to be true and has spent quite a bit of money on replacing oxygen sensors knows this is not true.
