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
How to check for a jumped timing chain or belt
This video can be used to support Section 1 pages 17-23 in my ebook.
The method of timing verification shown in this video can be used on any
car. Even on old school, non-computer controlled systems. I am also showing
in this video how to properly align the timing chains on a 2003 Suzuki
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
OTC #3857 TECH-SCOPE Introduction
The OTC Tech-ScopeTM is a standalone two-channel high-speed lab scope and
ignition oscilloscope with multimeter that allows service technicians to
quickly and efficiently test and measure virtually all of the electrical
and electronic components and circuits in a modern vehicle. The tool
features galvanic isolation not found on automotive scopes for hardware
protection and includes an ignition scope and a digital multimeter with an
The Tech-ScopeTM is capable of reading 40 million samples per second on
each channel with 10M ohm input impedance—eliminating the need for
special adapters to capture signals from critical components. The included
InfoTech software provides a vehicle-specific repair information database
for testing most common vehicle components with step-by-step test
procedures using a lab scope or multimeter.

Once again, Motor Age and TST teamed up to present professional technicians
with a free training resource, this time focusing on air conditioning
service and repair. Live attendees were told about the dangers of
counterfeit refrigerants and how to detect them, and shown new diagnostic
methods including thermal imaging and ultrasound detection.
And hey! Before you bust us on the sound quality...that's rain! This
webinar was shot during a heavy storm!

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.
Automotive Repair: Testing ECM Inputs and Outputs

Modern cars use dozens of electronic control units to perform a variety of
functions, from engine management to infotainment. Generally, these modules
are pretty tough but they still fail. The mistake is in replacing the
failed ECU without making sure you know what caused it to fail! Any of its
input or ouput devices could be the cause of its untimely demise. This
webinar shows how to make sure you don't fry the most expensive fuse on the
car! Click this link to subscribe to Motor Age! http://bit.ly/MA_YT_freesub

basic voltage drop testing for automotive electrical testing
How to use your meter to measure voltage drop in a automotive electrical
circuit. I do diagnostic jobs for many repair shops in my area, and one
thing I see all the time is the misdiagnosis of circuits and parts " hung"
that do not fix anything all due to improper testing.

To say I enjoyed making this video would be something of an understatement,
Paul Danner is a great teacher and he has some great diagnostic tools in
his class that are a lot of fun to play with, watch us as we go through the
process of diagnosing this Chevy pick up with a misfire, I think you'll be
surprised at what we find and how we find it.
Also check out ScannerDanners book on diagnosis, in a word it's awesome.
