To learn more troubleshooting techniques go to www.scannerdanner.com
Once again, this video covers why we need to learn proper troubleshooting techniques and to not be so reliant on manufacturer "flow charts". If you think your engine computer is bad, you must watch this video! Are there more tests that can be done to prove a computer is bad? What else should you check before computer replacement?
The following is a list of other tests and how to checks that were performed in this video:
1. How to test a 24x hall effect crank sensor
2. How to test sensor wiring integrity (both opens and shorts to ground)
3. How to test a hall effect cam sensor
4. How to test computer powers and grounds.
5. What is a shared reference circuit?
6. What do you do when you have low reference or power supply voltage to a hall effect?

The vehicle used for this case study is a Chrysler 300m.
Honda-Acura Surging Idle Speed (case study)
What causes a surging idle speed on a Honda or Acura? How to determine if
the cold fast idle valve is operating properly. How to adjust a cold fast
idle valve. How to test the IAC solenoid.
1996 Jeep No Start Case Study Part I
An example of what we do at Rosedale Technical Institute in Pittsburgh, PA.
This is an all live work school, no make-believe car problems here! My
students and I used this oppurtunity to review certain concepts and testing
proceedures written in an Engine Performance/Troubleshooting book I wrote
for my class.
1999 Dodge Avenger Misfire Case Study
A good review of Sections 21 and 22 of my eBook available at
In this video I show how to properly troubleshoot a misfire condition
caused by a misadjusted crankshaft position sensor.
1999 Honda Accord No Start (case study)
For more on Engine Performance Diagnostics go to my website at
I am doing field work in this video on a 1999 Honda Accord with an
intermittent no start complaint. Other symptoms include: stalling, long
crank times, surging, bucking, poor transmission shifting.
2003 Mercury Grand Marquis (how to test the cooling fan)
For more on Engine Performance Diagnostics go to www.scannerdanner.com
For this case study we have an electric cooling fan that will not turn off
on a 2003 Mercury Grand Marquis. In this video I cover all aspects of this
cooling fan system. From the inputs involved to the output controls and
detailed testing methods.
For more help with some of the terminology used and testing methods shown,
refer to Section 2 and 6 in my eBook available at www.scannerdanner.com or
the paper version available at www.aeswave.com
No Start Diagnostics Training at Rosedale Tech
Join me (Paul Danner aka ScannerDanner) and my class at Rosedale Technical
Institute while we troubleshoot a no start problem on a 1999 Subaru
Impreza. This was an unscripted video, everything was filmed live from
inside my classroom, with all of my students involved. For each new step in
the diagnostic process, I pause to explain what we are doing and why, so
this is a longer video than my normal upload, but I promise it will be
worth it. Even you veterans that are following me will learn some tips
along the way.
During my time teaching (14 years), I have developed a "field manual" to
help my students troubleshoot automotive electrical and electronic
problems. This book is available to you at www.scannerdanner.com as an
eBook. I also have lecture videos available to help you be part of my class
even more. With the purchase of the eBook, I will give you some of these
lecture videos for free.
Finally, if you are looking to go through auto technician training program,
I would love to have you as part of my class in person! We are located in
Pittsburgh Pa. For more information about Rosedale Technical Institute go

2000 Chevy S10 2.2L No Start (Part I)
For more on Engine Performance Diagnostics check out www.scannerdanner.com
This video is part one of a two part series. The following testing methods
How to check for spark, how to test if an engine is getting fuel when a
test port is not available, how to perform a relative compression test with
a picoscope, how to test if ignition timing is correct using a scope, how
to test a 7x crank sensor, and how to test a hall effect cam sensor.
I also show some of variables to the relative compression/timing test and
how the results at times can be misleading.
How to test an electric fuel pump (GM CPI case study)
For more info. on fuel system testing go to www.scannerdanner.com
This video covers the fundamentals of fuel pump pressure, amperage, power
and ground testing. The information contained in this video can be applied
to ANY electric fuel pump.
P0133 O2 Slow Response (2007 Hyundai Tiburon)
For more on O2 sensor testing go to www.scannerdanner.com.
This video covers some of the variables that can set a P0133 O2 slow
response trouble code.
What causes an O2 slow response trouble code?
What does an O2 signal look like in open loop?
How can you tell if a system is in closed loop?
How to identify O2 sensor wiring without a diagram.
O2 sensor frequency and amplitude testing.

This video is to be used with my next upload which is a 91 Buick 3300 with
good spark and no injector pulse.
Toyota Echo No Communication Case Study
This is a 2001 Toyota Echo with a no communication problem. You guys have
been asking for one of these and I finally have a good one that goes beyond
a blown fuse for pin 16 of the DLC. Also covered in this video is comparing
the ohmmeter to a voltage drop test and which one is more accurate.
Magneto Resistive ABS Wheel Speed Sensor Test
In this video we are working on a 2006 Chevy Colorado with a left front
wheel speed sensor code. This is a digital type wheel speed sensor, so
testing methods vary from the standard VR sensor.
