The vehicle being tested is
The vehicle being tested is 2010 Jeep Wrangler but the tests shown in the video apply to hall effect type cam, crank and speed sensors.
Video Breakdown:
Introduction clip
:52 - customer complaint (cam sensor fault code P0340)
1:32 - fault code list
3:57 - clearing and re-creating the code
4:30 - know your circuit designs! (ScannerDanner Premium)
5:45 - Snap-on guided component test meter for help with wiring
6:50 - pin voltage tests
7:50 - confirmed signal circuit integrity (engine computer is NOT the problem!)
8:40 - what the cam sensor signal looks like with engine running
11:00 - internal design of a "pull-down" type hall effect (picture from my book)
11:10 - step by step flow chart (picture from my book)
11:22 - description, operation and testing (picture from my book)
11:42 - making sure the pins were wired correctly (new harness connector was previously installed)
14:00 - inspecting the cam sensor for damage
15:36 - hand drawn picture of the trigger wheel
16:44 - visual of the trigger wheel (tone ring, cam sprocket)
17:53 - trigger the sensor with a piece of metal
20:00 - switching the 5v ref and ground on the sensor (was it wired backwards?)
26:35 - some bonus material provided by ScannerDanner Premium taken from this lecture https://www.scannerdanner.com/scanner...
28:17 - what a pull-down circuit looks like in a hall effect sensor
32:00 - how fast a pull-down type circuit can be tested (end of SD Premium portion)
32:42 - back to the Jeep with a new cam sensor
33:00 - how to set a proper air gap on an adjustable sensor
34:48 - comparing the old sensor to the new sensor when triggered with a piece of metal
37:00 - start-up with the new sensor (long crank time is fixed, code is gone, what scan data PIDs look like with a working sensor and what a good waveform should look like)
40:10 - final wrap up pf what we did and where to get more training (ScannerDanner Premium www.scannerdanner.com)
For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.

On ScannerDanner Premium I will bring you right into my classroom at Rosedale Technical College. You will find page for page lectures taken right from my book as well as exclusive classroom type case studies. What is so special about these classroom case studies? I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. There is no better on-line training of how to troubleshoot automotive electrical and electronics systems anywhere!
