Loss of seal in the combustion chamber, especially if that loss is intermittent, can be time consuming to diagnose and confirm with traditional testing methods. In addition, volumetric efficiency losses caused by problems like valve timing shifts, improper variable valve timing operation, and restricted Exhausts can also be difficult to nail down. But by using the power of an automotive lab scope and a few accessories, technicians can reduce their troubleshooting time and confirm faults that would otherwise elude them. And that's the topic of this Motor Age/TST webcast featuring guest expert Bernie Thompson of Automotive Test Solutions. Click this link to subscribe to Motor Age! http://bit.ly/MA_YT_freesub
2010 Subaru 2.5 Variable Valve Lift Solenoid and Switch Testing
This video is a great review of Section 2 "Switch Inputs" and Section 3
"Transistor drivers and Output Solenoids" in my eBook.
On this system the intake valve lift is varied by two different cam lobes.
A low lift lobe and a high lift lobe. I misspoke in the video calling this
a variable valve timing or VTEC mechanism. This system does not vary cam
timing, but it does vary intake valve lift.

John Q. Customer comes in complaining that the "Check Engine" light is on.
Drivability may or may not be affected depending on why the light is
illuminated. When facing this type of repair, consider whom you must really
satisfy in order to make the repair successful.
The same module that turned the light on in the first place is also the
same module that will test the quality of your repair. Even if your human
customer can't tell if the repair was correct, you can bet the module can.
And it will turn the MIL (Malfunction Indicator Lamp) right back on if it
isn't happy. So it pays to understand how the ECM performs its system
tests, and to use that information when performing diagnostic tests of your
own. And that's the topic for this month's edition of The Trainer! Click

Scoping Out Drivability: The Trainer video series (Nov 2011)
Diagnosing drivability problems on today's cars presents several challenges
to technicians. Many engine designs are unforgiving of even minor flaws,
and are quick to let their driver's know they aren't happy by bucking,
spitting, and turning on the Check Engine light. Finding these minor
discrepancies takes a trained eye, a little patience, and the right
One such piece of equipment is the Digital Storage Oscilloscope, or DSO.
This modern version of the old big-box engine analyzers many of us grew up
with is capable of much more than simply tracing secondary ignition
patterns. With the addition of a few accessories, it becomes a powerful and
time saving tool that can help you find those minor discrepancies when
other diagnostic techniques will not.
Join technical editor Pete Meier as he shares some of those techniques in
this month's edition of "The Trainer". Click this link to subscribe to

2003 Pontiac Vibe 1.8L Misfire, Rough Idle (Part 1)
This is a Toyota engine in this car and apparently is known for injector
problems. In this video I cover the following:
1. How to do an injector balance test with a timer tool.
2. How to monitor injector flow with a pressure transducer connected to the
fuel rail using a Picoscope
3. Using fuel trim for direction
4. How to use fuel trim numbers at different RPMs
Signal Circuit Integrity Update for my Ebook
This video is mainly for my eBook owners. I would like you to add this
additional information to your book.
How to safely check a sensor signal wire for opens and shorts without
having to disconnect the computer and use an ohmmeter.
Quick Tips for Evap Repairs
Global Leak Detection and TST present this seminar that is about how to
diagnose EVAP problems fast with a scan tool and a smoke machine. You can
use any scan tool and any OEM approved smoke machine such as a Smoke
Wizard, Bosch, OTC, MAC, and Snap On.
Voltage Drop Essentials - TST & Motor Age
G Truglia (TST) and Peter Meier (Motor Age) cover all the essentials of
using the meter, especially voltage drop testing. This training class has
been made free thanks tot he efforts of Motor Age and TST (an automotive
Fuel System Testing: Motor Age/TST November 2011 Webinar
In this Delphi sponsored webcast, Delphi's Dave Hobbs and TST's G. Jerry

Testing Engines with a Labscope
This is not a class on old-school engine diagnosis. The compression gauge
takes too much time to use. Using a labscope, easily diagnose a bad
cylinder and timing issues using relative compression and pressure
transducers. Extensive use of the Picoscope is covered.
Pete Meier of Motor Age, G "Jerry" Truglia of TST, and Bernie Thompson of
ATS all contribute to this presentation.
