Why O2 Sensors Fail To Calculate Exhaust Levels Over Time

As miles accumulate, O2 sensors effectively “catch a cold,” meaning they can’t breathe like they should.

VIDEO: Wide Or Narrow? What Is The Difference Between Oxygen Sensors And Wide-Band Air/Fuel Ratio Sensors?

In this video, Andrew Markel explores the difference between the two types of oxygen sensors and how the ECM sees the amount of oxygen left over after the combustion cycle. He also explains how new technology allows modern engines to see more of the fuel trim of the engine. Sponsored by NAPA.

Understanding Crankshaft Position Sensors

Modern engines need to know the position of the crankshaft and camshafts. Why? The timing of the valves, fuel injectors and ignition coils are continually optimized for the most efficient combustion event depending on the load and speed of the engine. But the other reason for knowing the position of the crankshaft is for misfire detection.

HVAC Sensors: More Than Just Temperature

HVAC systems have come a long way in the past 15 years. While the basics of heating and cooling may be the same, the controllers and sensors have improved dramatically. No longer does a driver have to worry about dealing with fogged-up windows or bad smells driving behind a semi-truck.

HVAC Sensors: More Than Just Temperature

When a driver sets a temperature in the control head of an HVAC system, what does it mean to the vehicle? Seventy-two degrees could mean many different settings depending on the outside temperature, humidity and even the position of the sun.

Omnicraft Introduces New Oxygen Sensors For Non-Ford/Lincoln Repairs

New to the Omnicraft line, OE-quality oxygen (O2) sensors are built with attention to detail and continuity testing that is approved and backed by Ford Motor Company.

Selling Four TPMS Sensors

If a single sensor has reached the end of its lifespan, it is highly recommended to replace all sensors at the same time. Similar to headlights, once one sensor dies, the rest are likely to be close behind. This is an important point for your customers to understand. Taking care of the issue before there is a problem also provides a convenience to them.

Rethinking Fuel Pump Diagnostics And Sensors

The technician diagnosed the 2011 Rogue as a bad fuel pump by squirting propane into the air intake. With propane, the engine runs, without propane, it stalls. But, after the fuel pump was replaced, the Rogue exhibited the same problem, which was a very slow, unsteady idle followed by an engine stall.

Oil Level Sensors – More Than A Warning Light

Oil level sensors have been used on import and domestic cars for more than a decade. Some of the first applications only monitored if the oil level was low using a switch attached to a float. The sensor would just trigger a message or light in the instrument cluster and only measured oil levels when the engine was not running.
