It could be that the oxygen sensor is malfunctioning in the event that it fluctuates.

The oxygen sensor is operating properly if the readings remain constant. It should be in the range of 100mV to 900mV. It should be within the range 100mV-900mV. If it's lower than this, it indicates the presence of a problem. If the readings are higher than the range it is most likely that the sensor is malfunctioning.

The oxygen sensor could be malfunctioning if the readings do not match this range.

Diagnostics cost

There are a myriad of factors that affect the final cost of car diagnostics. While most problems are simple, complex conditions can prove costly.
