Welcome to the ScannerDanner Free YouTube video page! We have YouTube videos from the beginning to September 2012 and January 2016 till now. We will be filling in the missing videos as time goes on. Please check back often!

This was the first time I have ever seen 12v on a potentiometer style throttle position sensor. The spec for this sensor is around .5v at idle at around 4v at wide open throttle and this Jeep was fixed at 12v all the time. Scan data was misleading as the TPS data parameter showed a constant 5v regardless of throttle angle. Also when performing signal circuit integrity type testing, you will now understand why we use a resistor instead of a jumper wire.

This is an excerpt from a case study I did on SD Premium. I really wanted you guys to know about the Picoscope Waveform Library and in this video I show where I am using it to identify a jumped timing belt on a 2006 VW Passat. Below are the links to the rest of this series on SD Premium.

This car had multiple problems. In this particular video I will be showing you the cause of fixed lean oxygen sensor signals (both banks) and very positive STFT and LTFT numbers. I will also show you how to use fuel trim after the repair to determine if you have any other problems.

This seems to be a common complaint on this car. Though I did not find anything with my visual inspection of the IAC valve, a new IAC valve or solenoid did fix this issue.

In this video I will walk you through some basic tests on verifying spark, injector pulse and fuel pressure. All you need is a digital multimeter and a small pocket screwdriver. I will be using the Power Probe IV but this is not a necessary tool to handle this problem.

After showing you guys (and my class) the operation of an oxygen sensor on a motorcycle, I used this opportunity to discuss a very difficult topic from chapter 5 in my Engine Performance Diagnostics book. The topic is "Oxygen Sensor Bias Voltage".

Join me and my entire class at Rosedale Technical College as we take a field trip to Latorre's Auto to troubleshoot some problem cars. This is one of four that we did together. One of them didn't make it on camera (broken timing belt on an Eclipse) and two other ones that did that are available on SD Premium.
