Air-fuel ratio measurements are communicated to the PCM/ECU of a car by the oxygen sensor. Additionally, the engine's mixture is determined by barometric pressure, altitude, ambient temperature, and engine temperature.

If an O2 sensor fails, fuel injection levels won't be accurate, exhaust gases won't be regulated, and fuel combustion won't be efficient. Furthermore, the vehicle's engine performance may be subpar - resulting in harmful environmental pollutants being released.

It is important for drivers to know how to spot O2 sensor symptoms early on because they play such a crucial role in overall vehicle performance and emissions. Poor gas mileage, intermittent stalling, and a persistent Check Engine Light are just some of the signs to watch out for. How do you know if your O2 sensor is bad?

Unsatisfactory Mileage

In the event that a driver notices that he does not get the usual mileage per gallon numbers, it is possible that the Lambda sensor is not sending the vehicle's computer notifications to alter the air/fuel ratio, resulting in an air/fuel mixture that is too rich, wasting fuel. As much as 40% of mileage can be increased by replacing a faulty sensor, according to Fueleconomy.gov.

Hesitation or Unusual Lurching

During a red light or stop sign, a driver who feels the vehicle wants to surge ahead might notice an early sign of Lambda sensor failure in the form of uneven idle. If the driver applies the accelerator, the vehicle hesitates after the driver presses the accelerator.

Failed Catalytic Converter

It has been reported that red-hot heat can generate thermal failure when the air/fuel mixture is too rich and not corrected. A ceramic monolith could melt in this situation, blocking the vehicle's exhaust path. There may be a significant reduction in engine power depending on the extent of the damage.

Light on the dashboard

There is a possibility that the "Check Engine" light will illuminate. A reputable technician must check the code for a vehicle owner.

Smell

When there is unburned oxygen in the catalytic converter of a cold engine with a faulty Lambda sensor, the engine may smell like rotten eggs.

Cruising at Cruising Speed Results in a Decrease in Engine Power

An erroneous indication that the air/fuel mixture is too rich may be sent by a malfunctioning Lambda sensor. As a result, the vehicle's computer will reduce the amount of fuel in the ratio based on the Lambda sensor signal, causing the spark plugs to misfire.

Failure of the Emissions Test

An ill-functioning Lambda Sensor can cause harmful emissions to be released into the atmosphere (unused hydrocarbons and carbon monoxide).
