Stays fixed at a particular voltage; Web several of the most obvious signs that the oxygen sensor is failing include: Web oxygen sensors detect the amount of oxygen content in the exhaust stream and turn this information into a voltage signal that your car computer uses to control fuel ratio and emissions.

In Essence, This Could Mean That There’s An Excess Of Oxygen In Comparison To Fuel In The Combustion Chamber.

The o2 sensor can be considered a small battery that has an operating range of 0 to 1 volt when fully warmed up to 600°f. One or two wire unheated oxygen sensors should be inspected or replaced every 30,000 miles. If the oxygen content of the discharge gases is too high or too low after the catalytic converter, it means the cat converter is not working properly and may need to be replaced. Web a simple test using the scanner to see if the o2 sensor is capable of reading correctly while monitoring the o2 voltage is to make the fuel mixture artificially rich by feeding propane into.

However, A Voltage Output, Higher Than The Base Amount Around 0.8 V (800 Mv) Dc., Would Indicate A Rich Mixture.

This voltage range can vary slightly depending on. The oxygen (o2) sensor can be used as a diagnostic tool on today's computerized vehicles. Web the base voltage is approximately 0.45 v (450 mv) dc., keeping the air and fuel mixture, at the optimal ratio. Web in most vehicles, the downstream o2 sensor should produce a steady voltage of approximately 0.45 volts for optimal fuel or oxygen usage.
