Tech Tip: Replacing a Worn Oxygen Sensor increases Fuel Economy and Improves Overall Performance
Oxygen sensors play a critical role in the clean and efficient performance of a vehicle’s engine. However, it can be hard to tell when an oxygen sensor on a vehicle is beginning to wear out or has stopped functioning altogether. Shops see the big red flag most often when the vehicle fails the emissions inspection or if the check engine light appears on the dashboard. Otherwise, the symptoms of a slow or worn out oxygen sensor are not obvious, and, therefore, oxygen sensor check or ….
Oxygen Sensors: Are You Up to Date on the Latest Designs?
If you’re a technician who works on late-model import vehicles and diagnoses engine performance and emissions problems, you probably have a good understanding of how oxygen (O2) sensors work. You know that all late-model engines have at least one or more “upstream” O2 sensors in the exhaust system to monitor the air/fuel mixture, and one
DENSO Sales California Releases New 2008 Oxygen Sensor Catalog
DENSO Sales California has announced the availability of its new 2008 Oxygen Sensor catalog (#O2-cat-0608), which includes 344 new oxygen sensor part numbers, adding 8,095 new applications to cover an additional 57 million vehicles in operation. The catalog covers domestic and import automotive, light truck and van applications ….
Bosch Celebrates Production of 500 Millionth Oxygen Sensor Since Introducing it in 1976
Bosch celebrated the production of the 500 millionth oxygen sensors in May. For 32 years, this vital component has played a major role in reducing automotive emissions. Placed in the exhaust gas flow of an internal combustion engine, the automotive oxygen sensor measures the oxygen content in the ….
Tech Tip: The PCM Relies on Good Information from the Oxygen Sensors
Do you know your oxygen sensors? Oxygen sensors have been used for more than a quarter of a century, dating back to 1980 when the first computerized engine control systems appeared. The oxygen (O2) sensor is part of the fuel management system. It monitors unburned oxygen in the exhaust. The powertrain control module (PCM) uses this information to determine if the fuel mixture is rich (too much fuel) or lean (not enough fuel) ….
Tech Tip: Oxygen Sensors Help Maximize Performance
Computerized engine control systems do an amazing job of keeping engines in good tune, minimizing emissions and maximizing performance and fuel economy. To keep everything humming at peak efficiency, the computer needs good inputs from all of its sensors. Key among these are the oxygen (O2) sensors.
When Should You Replace an Oxygen Sensor?
Is there a mileage or time requirement for oxygen sensor replacement? Simple answer: No. Oxygen sensors were first used for fuel trim and emissions in the late 1970s and into the mid 1990s. A single sensor was installed into the exhaust stream to modify fuel delivery and maintain catalytic converter efficiency. Beginning January 1, 1996,
Diagnostic Solutions: Oxygen Sensor Diagnostics
Once considered leading-edge technology, today’s oxygen sensor has become a commonplace service item on modern vehicles. Popularly introduced in the 1970s, the Lambda or, as it’s more popularly known, the oxygen sensor, rapidly became standard equipment as it’s a vital component of closed-loop or feedback fuel control technology. By using a voltage input from the
DENSO Introduces Oxygen Sensor Training for Service Technicians
DENSO Sales California, Inc. has introduced an oxygen sensor training and promotion kit designed especially for professional service technicians.
Oxygen Sensors – Monitoring Converter Efficiency
In 1996, automakers did the aftermarket a huge favor. They added "downstream" oxygen (O2) sensors to their vehicles. The downstream O2 sensors are located just behind the catalytic converter, or on some Fords, in the converter itself.
