Volumetric Efficiency Diagnostics

A few years ago, I obtained an OBDII scan tool/dynamometer simulation/calculation program that can graph volumetric efficiency (VE) over rpms. Using real world vehicles, and no useful instructions, I devised a test sequence that allows a technician to see things another way. What is Volumetric Efficiency? Let’s keep this simple to start. An engine is

Making Money with Mode $06

Nothing is more frustrating than “fixing” a customer’s vehicle and then have it come back a few days or weeks later with the check engine light on and the same fault code or a new fault code. You look bad, lose your customer’s confidence in your ability to fix their vehicle, and in states that

20 Years of OBDII Connection

In 1994, select Toyota, GM and Ford models were sold with OBDII emission systems. To the amazement of many technicians, all of these models came with the same ­diagnostic connector called the data link connector or DLC. In 1995, 40 percent of vehicles sold had a common DLC. By the 1996 model year, all vehicles
