Bosal Launches New Catalytic Converter Catalog
Bosal’s new Catalytic Converter catalog covers the company’s comprehensive line of direct-fit and universal catalytic converters for cars, vans, SUVs and light trucks. Application coverage ranges from 1975 to 2007 for both import and domestic vehicles. The new catalog includes ….
Tech Feature: Catalytic Converter Diagnosis
The catalytic converter is probably the most important emission control device on a vehicle because it cleans up the pollutants in the exhaust. Thanks to fuel injection, oxygen sensors in the exhaust manifolds, and a feedback fuel control system, emissions are kept to a minimum. Even so, some pollution is still produced and must be eliminated by the converter. So the converter must be in good condition and working correctly to keep tailpipe emissions to an ….
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
‘Sensing’ Problems: A Drop in Fuel Economy and Higher Exhaust Emissions Signal O2 Sensor Replacement
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. Part of the fuel management system, the oxygen (O2) sensor monitors unburned oxygen in the exhaust. The powertrain control module (PCM) uses this information to determine if the fuel mixture
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 ….

Diagnose and Solve the Root Cause of Sensor Failure Before Sensor Replacement
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) ….
Volvo Tech Tip: Updated Routing of O2 Sensor Wiring
New routing has been developed for oxygen sensor wiring on 1997-1998 Volvo 850 models, S70/V70/C70, to prevent contamination from reaching the probe’s reference air. If one oxygen sensor is replaced, the new adapter wiring must be installed for both sensors.
