8 Common Diagnostic Mistakes
Many diagnostic mistakes that become “diagnostic dilemmas” are caused by basic oversights or incorrect assumptions on the part of the technician. Research time and testing time have become the cornerstones of modern diagnostics.

Diagnosing A P0301 Misfire Code On A 2001 Mercedes-Benz E320 Sedan
Since the advent of OBD II, every vehicle is equipped with a sophisticated system that measures each cylinder’s contribution to engine power, becoming one of the most difficult challenges we face. Each time a cylinder fires, the misfire monitor uses a highly accurate crankshaft angle measurement to measure the crankshaft position. This system needs to have an accurate crankshaft position sensor that is able to read the crankshaft position, even at high RPM, sending a clear signal to the PCM. Then the PCM monitors the crankshaft acceleration time for each cylinder at the firing time.
Memory Lane: Welcome To My World
I have often been accused of living in a time warp. And, I would have to plead guilty, but with an explanation. All of my customers are working on vehicles that are 60+ years old or older, so that’s the environment I am in every day.
Tuning In To The EFI Market
There are many variables that need to be calculated and calibrated when it comes to electronic fuel injection (EFI), but simple fuel flow is just the beginning. EFI goes far beyond a replacement for a carburetor, and the electronic part of the equation is where these systems seem so complicated. Many EFI systems give you the ability to control a wide range of parameters of the vehicle, so it’s more involved than simply controlling fuel flow.
Diagnostic Dilemmas: Approaching No-Code Diagnostics
Thanks to the increasing reliability of modern vehicles, most diagnostic technicians are seeing fewer pattern-failure driveability complaints. For that reason, many techs won’t gamble expensive shop time chasing an illusive no-code driveability complaint. Instead, many will write “no problem found” on the repair order and move on to the next vehicle. Unfortunately, at some point in time, the intermittent, no-code driveability will either be solved or the vehicle will be traded or sold for scrap.

Maximizing Current Ramping Techniques In The Shop
Although modern on-board diagnostic systems are becoming far more comprehensive than in years past, it’s still important to know how to use a lab scope and inductive current probe to analyze the amperage flow through the primary ignition and fuel pump circuits.
