Oil Pumps & the Engine’s Lubrication System
p can restore gear-to-gear clearances but not gear-to-housing clearances. The end plate that covers the pump often develops a heavy wear pattern that is most noticeable on the outlet gear side. Regrinding the face of the plate smooth can restore end play tolerances between the plate and gears but it can’t compensate for wear inside
Diagnostic Dilemmas: The Effects of Warm-Up Laps on a Running Engine
Most diagnostic technicians have experienced the frustrations of troubleshooting temperature-related engine performance problems. All too often, the true nature of the problem is concealed by the very fact that it occurs only at specific engine temperatures. If the engine quickly passes through the critical temperature range needed to duplicate the problem, the problem can easily
The Origins to a Breakdown
It’s interesting to see the look on a technician’s face as a vehicle gets towed into a shop on the back of a truck. That’s the opening scene for a no-start problem. You can usually tell when a technician thinks it’s good, and you can definitely tell when he thinks it’s bad. Not many techs
The Top 5 Favorite Tools of the Country’s Top Technicians
Dan & Kris Cesena Honda Hospital, Inc. San Mateo and Milpitas, CA Our top five favorite tools (and why) are: The Snap-on MicroVAT Battery/Starter/Alternator Tester. Why? Well it makes it much easier to test batteries, alternators and starters; it has an infrared port, which sends the data to an optional thermal printer; and with these
Detouring Comebacks
se, how you handle (or prevent) a comeback becomes even more important to the success of your shop. Go ahead ‹ ask yourself, “Am I allowing comebacks at my shop to get out of hand?” First, don’t be discouraged. There will always be some comebacks. According to one shop owner, you can expect about a
Checking into Mode $06
Mode 06 is the actual system test data that OBD II looks at when it decides to set a pending code or a current fault code. If the test data is within the limits established by the vehicle manufacturer, the item gets a PASS and no codes are set. But if a value is out of range, OBD II flags it with a FAIL and keeps an eye on the component until the system monitor has run at least twice. Then, if the problem is still there, a DTC is set and the MIL light comes on.
Selling Service for Low-Maintenance Ignition Systems
ition system maintenance as long as it feels like it’s “running good.” In reality, spark plugs eventually develop high electrical resistance because the electrodes wear away. When this happens, the secondary ignition voltage will increase until the ignition coil, ignition cable, spark plug boot or spark plug develops a high-voltage leak. When a high-voltage leak
Selling Oxygen Sensors
As modern OBD II technology marches on, it’s clear that the zirconia-based oxygen sensor now is being sold more as a basic repair part than as a preventive maintenance part, and it changes the way we diagnose and sell oxygen sensors. To illustrate the difference, let’s remember that an oxygen sensor replacement used to be
Diagnostic Dilemmas: Playing the Diagnostic Shell Game
More often than not, deciphering diagnostic trouble codes is like playing a high-tech version of the old circus sideshow “shell” game. In the trouble code shell game, we are led to believe that the pea (diagnostic solution) is hidden under one of the shells (DTCs) stored in the diagnostic memory. Unfortunately for the diagnostic technician,
