Honda Electric Power Steering

The first patent for power steering, granted in 1900, describes a mechanical system that never went into production. Hydraulic power steering was developed in the 1920s, and it was first used on big Army trucks in the 1940s.


Electrical Wiring Basics

This article provides a basic primer regarding wire types, gauges and more, for a better understanding of the wires we deal with on a daily basis. Granted, this information may not apply directly to all OEM wire, but it will provide a better understanding of wire basics.


Emissions Gas Analysis: Five-gas Analysis and the Importance of Lambda

The actual combustion process that takes place in the modern vehicle with a gasoline engine hasn’t changed much since the four stroke engine was invented well over 100 years ago. Yes, it’s been immensely fine-tuned to reduce the pollution that it creates and increase the fuel economy that we get when we fill up the tank, but the exhaust that is created is the same. When gasoline as a fuel is burned, chemically we should only get a few things; water (H2O) carbon dioxide (CO2) and heat.


Don’t Lose Your Cool

Look around as you drive along your daily route. Chances are, you’ll notice a few late model vehicles that feature curiously small grille areas. You may wonder how the engine maintains proper temperature with such tiny air inlets.


Tool review: Midtronics' DSS-7000 battery analyzer -- A very sophisticated diagnostic tool

If you're thinking that the world doesn't need another battery tester, you haven't seen Midtronics' DSS-7000. Comparing this tool to a good/bad tester or a multimeter is like comparing the space shuttle to a child's kite.


Brake basics booster shot

When was the last time you had a tetanus shot, asks the doctor when you arrive to have that cut stitched up. You need a booster every 10 years. Every year, 10% to 20% of people who contract tetanus will die. Auto repair is risky business. Make sure your booster is up-to-date.


Ford Powerstroke diesel: Engine background and tech tips

As anyone familiar with diesel engine operation knows, a diesel engine differs from other liquid fuel engines in one major respect: The fuel/air charge is ignited by cylinder pressure and heat, instead of via an electrical ignition system (diesel-fueled engines don’t use spark plugs).


Camry generations five and six: A brief tour of the Toyota Camry fuel and EVAP systems

Since the day it was introduced to the U.S. market, the Toyota Camry has been one of the most reliable cars on the road. With normal maintenance or even a fair amount of neglect, it seems these cars almost never break down. When problems do arise, the diagnosis is rarely a challenge.


Advanced O2 sensor diagnostics: Tracing sensor wiring and checking for ‘lazy’ sensors

Over the years we covered a lot of the basics concerning oxygen and air-fuel sensor diagnostics. This includes their basic operation, the differences between oxygen and air-fuel sensors, air-fuel ratio sensor voltage specifications, the differences between zirconium and titanium dioxide oxygen sensors, and using emissions analyzers to verify Lambda.
