Remove O2 Sensors with LTI Shockit Socket Kit
Shockit Sockets access, loosen and remove frozen O2 sensors.
Maximize Engine Potential With O2 Sensors, Tuning
Oxygen sensors and the closed-loop EFI systems that utilize them can unlock amazing levels of performance.
Seeing The Big Picture With AFR Sensors
Air/fuel ratio (AFR) sensors have become commonplace in today’s automobiles, taking over where traditional O2 sensors have left off.
VIDEO: Nissan Maxima Mass Air Flow Sensor Codes
Andrew Markel explains how a mass air flow code and an oxygen sensor code on a Nissan Maxima can be solved with one simple check.
TPMS Give & Take – Common TPMS Sensor Corrosion
For TPMS sensors, a harsh environment isn’t a requirement to see valve seizing corrosion take hold.
MAF Sensor Installation Tips
A Mass Airflow (MAF) sensor, also known as an “air meter,” measures the mass of air entering the engine air intake at any given time. When a MAF sensor is used in conjunction with an oxygen sensor, the engine’s air/fuel ratio can be controlled with great accuracy. The MAF sensor provides the ECU with predicted
O2 Sensors Keep Watch Over The Air-Fuel Mixture
Keeping an eye on the air/fuel (A/F) mixture is an essential function of the engine management system because it affects emissions, fuel economy and performance.
Failing O2 Sensors Result In Increased Emissions And Fuel Consumption
The engine computer needs to know what the fuel mixture is with a high degree of precision so it can optimize fuel economy as well as emissions. If the information received by the powertrain control module (PCM) from its sensors is not accurate, it may command too much fuel or not enough.
Service Advisor: Diagnostic Tests for Catalytic Converters, O2 Sensors
The X1 ASE Certification Test has a section (eight questions) focused on emissions system diagnosis.
Component Connection: Emission Control — O2 Sensor Diagnostics
In recent years, the design of O2 sensors has changed. The ceramic thimble-shaped element in zirconia-type O2 sensors has been replaced by a flat strip ceramic “planar-”style sensor element.
