Tech Tip: 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.
Eastern Introduces New 2006 Catalog Featuring Catalytic Converters and Related Components
Eastern Manufacturing, a manufacturer of catalytic converters and related components, has introduced a new catalog, which features the complete line of direct-fit, performance and universal catalytic converters for cars, vans, and light- and heavy-duty trucks.
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. The training kit features a 12-minute sales training video that provides detailed information for the professional technician on how to explain to consumers just how oxygen sensors function, the importance of conducting regular system checks and why proper servicing of oxygen sensors is important to maximize a vehicle’s performance.
Exhaust & Emissions: Converters & O2 Sensors
What’s the most important emissions control device on a vehicle today? The catalytic converter, because it cleans up any exhaust pollutants that exit the engine. It’s a hot job (literally) with operating temperatures running between 600 to 1,000
Tech Tip: Air Flow Sensors – Understanding Their Function and Potential Problems
Most of us remember the "good old days" when an engine’s air/fuel (a/f) ratio was controlled by a mechanically operated carburetor. Due to the inherent design limitations of mechanical systems, however, carburetors don’t respond efficiently to changes in barometric pressure, temperature and humidity.
Diagnostic Solutions: Air Flow Sensors…Understanding Their Function & Potential Problems
Most of us remember the “good old days” when an engine’s air/fuel (a/f) ratio was controlled by a mechanically operated carburetor. Due to the inherent design limitations of mechanical systems, however, carburetors don’t respond efficiently to changes in barometric pressure, temperature and humidity. In the quest for improved fuel economy and reduced exhaust emissions, import
Replacing Oxygen Sensor: Saving the Environment and Your Customer’s Catalytic Converter
The oxygen (O2) sensor is the master switch in the fuel control feedback loop. The sensor monitors the amount of unburned oxygen in the exhaust and produces a voltage signal that varies from about 0.1 volts (lean) to 0.9 volts (rich). The computer uses the O2 sensor’s signal to constantly fine tune and flip-flop the
Monitoring Emission Efficiency With O2 Sensors
As modern OBD II technology marches on, it’s clear that the zirconia-based oxygen sensor now is being sold more as a basic repair part than as a preventive maintenance part, and it changes the way we diagnose and sell oxygen sensors. To illustrate the difference, let’s remember that an oxygen sensor replacement used to be
