Oxygen Sensors And Catalyst Efficiency
Newer air/fuel ratio or wide-band sensors can detect a wide range of fuel conditions.
Completing Catalyst and Oxygen Sensor Monitors Post Repair
The biggest challenge of an oxygen sensor or catalytic converter replacement is completing the catalyst and oxygen sensor monitors to confirm the fix. This webinar will cover what it takes to complete the monitors and diagnostic strategies post-repair.
Diagnosing Oxygen Sensors
Picking the right tool is critical. This video is sponsored by Auto Value and Bumper to Bumper.
Understanding The Operation Of Oxygen Sensors
They play a vital role in achieving the stoichiometric ideal – but there’s more to it than just that.
Oxygen Sensor Questions Answered
If an O2 sensor is not reading properly or is borderline, it should be replaced regardless of its age or mileage.
VIDEO: Tips For Removing Seized Oxygen Sensors
Andrew Markel covers Nissan TSB NTB10-009b and the strategies for removing seized oxygen sensors in downpipes and exhaust pipes.
VIDEO: Wide Or Narrow? What Is The Difference Between Oxygen Sensors And Wide-Band Air/Fuel Ratio Sensors?
In this video, Andrew Markel explores the difference between the two types of oxygen sensors and how the ECM sees the amount of oxygen left over after the combustion cycle. He also explains how new technology allows modern engines to see more of the fuel trim of the engine.
VIDEO: Understanding Oxygen Sensors And Air Fuel Ratio Sensors
Early oxygen sensors could only see a very narrow range of the air/fuel ratio. Modern air/fuel ratio sensors can see a wider range of lean and rich conditions. Andrew Markel discusses what this means to your diagnostic approach when it comes selecting the correct sensor for the job.
Oxygen Sensor And Catalyst Efficiency
The catalyst efficiency monitor verifies that the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within predetermined values.
Oxygen Sensor Heater Codes
One of the most difficult problems to cure is an oxygen sensor code related to the heater circuit. If you decide to just put in a new sensor and clear the codes, there is a chance the code will come back because the malfunction in the circuit is not in the oxygen sensor.
