Salut. As vrea sa stiu cum stati voi cu voltajul de la cei 2 sau 4 senzori de o2, la mine se joaca intre 0.8 si 0.1 cea ce din ce am citit pt senzorul dinaintea catalizatorului e bine, dar nu stiu cum ar trebui sa fie la cel de dupa catalizator...... de precizat ca am avut un p0402 ( eficienta catalizatorului sub pragul limita) la mine valorile sunt cam egale atat inainte cat si dupa cat. La itp ( facut acu 2 sapt nu am avut nici o problema cu emisiile de co2 )
A doua intrebare... mixul aer/bemzina este calculat dupa primul senzor sau ii ia in calcul pe amandoi ???
From the oxygen content, the ECM can determine if the air/fuel ratio is rich or lean and adjusts the fuel mixture accordingly. A rich mixture consumes nearly all the oxygen, so the voltage signal is high, in the range of 0.6 - 1.0 volts. A lean mixture has more available oxygen after combustion than a rich mixture, so the voltage signal is low, 0.4 - 0.1 volts. At the stoichiometric air/fuel ratio (14.7: 1), oxygen sensor voltage output is approximately 0.45 volts
