Analyzing Oxygen Sensor Failures

Keeping the internal combustion engine as close to the stoichiometric ratio as possible will result in optimum catalytic converter efficiency and fuel economy. The stoichiometric ratio simply means that all the air (14.7 parts) and fuel (1 part) going into the cylinders are being converted to water and carbon dioxide exiting the exhaust. This is the perfect combustion reaction, but this desired stoichiometric operation can’t happen without fuel control.

How to Isolate the Issue and Service Them

Unless you have just started in the automotive field in the last few weeks, you likely have faced this work order. A customer is concerned about exhaust noise. You get in the vehicle and start the road test. The exhaust is quiet, but the familiar hum or growl of a wheel bearing is oh so familiar.

Developing Diagnostic Strategies

It’s Important to Establish a Plan of Attack

Performing diagnostics is something many of us do each day, without much thought, but most seasoned technicians have a detailed diagnostic approach that they employ. They have an action plan — a diagnostic checklist — that they follow from start to finish with remarkable success.

Engine Oil Technology

There’s More to Consider Than Merely Viscosity Numbers

While the installation of the correct engine oil may not be an important item to a customer when they arrive at our shop for service, the type of oil that is installed in the engine is beyond important. As technicians it is our job to ensure that the correct engine oil is installed that will meet or exceed what the manufacturer expects.

Spark Plug Tech

Interpreting Spark Plug Condition

The spark plug has a straightforward job to do. It’s responsible for igniting the air/fuel mixture in the engine’s combustion chamber initiating the power stroke. But this task is far from simple. The spark plug’s operating environment is extreme with combustion temperatures reaching 1500 F and peak cylinder pressure reaching 1,000 psi or more.

Overview of a Modern Electronic Power Steering System

EPS Isn't New, But It Has More Capabilities

Electronic Power Steering (EPS) is now standard equipment on virtually all new models of vehicles sold. One reason is clear: it removes the parasitic drag of the constantly turning, belt-driven hydraulic pump used to supply the hydraulic force to move the steering mechanism.

MAF System Diagnostics Need Special Attention

Mass Airflow Sensors are Critical for Obtaining Proper Air/Fuel Ratio, but Understanding This Sensor is Important for Diagnostic Efforts

For an engine to run most efficiently and supply the catalytic converter with the proper gasses, it can convert to non-harmful emissions, the engine’s air-fuel ratio must run as close to the proper stoichiometric ratio as possible.

Examining Coil On Plug

The Most Reliable and Durable Ignition System to Date

Today’s modern ignition system normally will use a single ignition coil per cylinder, mounted directly or very close to the spark plug: the Coil On Plug (COP) design. Some systems use an individual coil and a small ignition wire in a Coil Near Plug (CNP) setup because the location of the spark plug in the cylinder head won’t allow enough room to directly mount a coil on the spark plug, I consider this a version of COP.

Keeping Up With Change: Continual Research and Education Is Vital

Automotive technicians all have their own individual style and approach to diagnostics and education. But most techs will tell you that if they understand how the system is supposed to work and the components involved, the diagnostic repair journey is usually easier. Automotive technology is constantly changing, it never seems to stop, but keeping up with this constant change is a demanding task.

Diagnosing a MOST Bus Code

When We Have a Failure to Communicate

Diagnostics can seem tricky and daunting at times. Just the sight of a “U” based code can be intimidating to even the best diagnostic technicians, but if a U0028:00 MOST bus code is set and you are dealing with the complaint of no center stack or no radio operation on a GM car or truck, where do you even start and what the heck is the MOST bus?
