We urge people not to drive with a faulty oxygen sensor as the powertrain is not operating on the right fuel combination. Even though it may appear okay, if the powertrain excessively uses fuel, it could obstruct the catalytic converter. Driving can be laborious and bumpy if the oxygen sensor is malfunctioning, as well as being inefficient with fuel and producing noxious exhaust. If the damaged sensor is left unaddressed for a considerable length of time, it could result in major issues with the motor and catalytic converter requiring significant expenditure to remedy or replace.
