Singapore Nissan Oxygen Sensor

Description

CAN YOU DRIVE WITH A BAD OXYGEN SENSOR?

The short answer is “Yes,” your vehicle’s engine can operate without oxygen sensors. But without them, your PCM won’t know how much fuel to inject into the engine. Depending on how it fails, you may end up with an overly rich fuel mixture, drastically reducing fuel economy and clogging your catalytic converter with excess, unburnt fuel. This excess may become burnt in the catalytic converter, raising its temperature and potentially shortening its lifespan.

Note: It’s much cheaper to replace an oxygen sensor than a catalytic converter. 

So are oxygen sensors necessary? Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
