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
Selling Oxygen 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
DENSO Expands Its Line Of Oxygen And Air/Fuel Sensors
Today’s automotive engines are extremely sophisticated and are controlled by state-of-the-art onboard computers. If a sensor malfunctions, it can reduce fuel economy or negatively affect emissions. That’s why DENSO First Time Fit Oxygen and Air/Fuel Sensors are designed to meet or exceed the original equipment tolerances set by the manufacturers. DENSO has just released its
DENSO Makes It Easier To Find The Right Oxygen And Air/Fuel Sensors
DENSO has just released their 2013 First Time Fit Oxygen and Air/Fuel Sensor Catalog that offers one of the most complete product lines in the industry, said the company. It includes 67 new oxygen sensor part numbers to cover an additional 7.7 million units in operation.
DENSO Sales California Releases New 2012 Oxygen and Air/Fuel Sensor Catalog
DENSO Sales California has announced the availability of its new 2012 Oxygen and Air/Fuel Sensor Catalog (#O2AF-CAT-0412), which includes 98 new oxygen sensor part numbers, adding 959 new applications to cover an additional 7.2 million units in operation.
Mass Air Flow Sensor Cleaners
What can you do both for maintenance and for service and diagnostics to confirm a mass airflow sensors functioning properly? Andrew Markel shares the secret in this video sponsored by Auto Value and Bumper to Bumper.
Adapting Sensors For Changing Inputs
Let’s focus our attention today on one small facet of the technology inside modern vehicles: Adaptations.
Fuel Trim Diagnostics: Should You Trust The Sensors?
Fuel-injected engines can adjust the fuel trim by altering the injector open time. The longer the open-time of the injector, the greater amount of fuel is injected into the engine.
Catalyst Efficiency Monitors: What Are The O2 Sensors Telling The PCM?
The catalyst efficiency monitor verifies that the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within the predetermined values. The PCM compares the signals from the upstream and downstream oxygen sensors to determine the state of the converter. These “tests” are called readiness monitors.
O2 Sensor And Air-Fuel Ratio Troubleshooting
The key to locating bank one/sensor one, is to identify the #1 engine cylinder. In a V-type motor, sensor one is in the exhaust system before the catalytic converter. In an inline motor, the rear sensor (or sensor two) is in the exhaust system after the catalytic converter.
