Bosch Named Exclusive NASCAR Performance Partner, Oxygen Sensor Supplier for NASCAR Fuel Injected Engines
Bosch developed and introduced the automotive oxygen sensor in 1976, and as NASCAR makes the switch from carburetion to fuel injection in 2012, Bosch will be its exclusive oxygen sensor supplier.
Bosch Expertise on Oxygen Sensors for Vehicle Manufacturers Benefits the Aftermarket
Bosch has been manufacturing and supplying automotive parts and systems to vehicle manufacturers since the very beginning of the automobile. As inventor, manufacturer and supplier of many ground-breaking automotive technologies – such as the oxygen sensor which was introduced in 1976 – to original equipment manufacturers (OEMs), Bosch enjoys a unique position in being able to bring OE-level quality, fit and function to its aftermarket products.
Tech Feature: Oxygen Sensors are Key to Performance and Fuel Economy
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).
Code P0420: Diagnostics of Catalytic Converter Replacement and Oxygen Sensors
You just pulled a P0420 from a vehicle indicating the catalyst system efficiency for one of the banks is below threshold. What is next? Could it be just the oxygen sensor? Or, could it be the catalytic converter? These articles will help you understand why the OBDII code was set and what further test must be performed to determine the root of the problem like a coolant leak, oil blow by or other problems with the engine.

Diagnostic Solutions: Rediscovering Oxygen Sensors
If you’re like me, you more often than not find a correct diagnostic direction by going back to what trainers are fond of calling “The Basics.” I capitalized “The Basics” because they are the foundation upon which all of us should be building our diagnostic strategies. The Basics were brought to mind recently when I
Oxygen Sensors Read the Amount of Unburned Oxygen in the Exhaust
The O2 sensors located in the exhaust manifolds provide the essential feedback for the fuel control loop that regulates the air/fuel mixture. On V6, V8 and V10 engines, there is one O2 sensor in each exhaust manifold. On four and straight six engines, there is usually only one O2 sensor in the exhaust manifold.
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
