Testing Reference Voltage and how it is affected when Shorted. 

"The scanner told him "!!! I love that. I wish my scanner told me what to change. I gotta get me one of those. But his parts cannon is definitely defective. Nice job sir

Perfect example of why we test and don’t just throw parts at things. Good fix!

You are good at teaching ,and I like the clear zoom in so we can see better.👍

These Trained By Techs videos are a great idea! TYVM for taking the time to make these. Look forward to more of them. Great job. Take care

After a correct diagnosis, and no need for the parts cannon, the happy dance is always mandatory🤣👍🇦🇺

Good theory and follow through. In this case you searched for a common denominator, but I'm sure if you would have followed through on any 1 of the components throwing the code, you would have found it anyway. Great job!

Diagnosed and repaired professionally! Great Video!

Cool vid. You DID get a code for the Accelerator Pedal Position sensor. It was the 1st code, it said "TPS/APP circuit low". Thats why the PCM didnt just throw a TPS code by itself...seeing how it could have. It gave you enough to have to take a look at the APP.

Thank you very much for sharing your videos. Good job. Bless you

Good video, and a great example of why you should ‘test not guess’. 👍

The dance jig at the end was cool!

Great video Carlos , please i hope you have the time to make more of them .

Awesome works sir. I really enjoy your videos. Cheers

Strange. I felt a “Rocky Mountain High” when you found that shorted wire in the harness

Yep the same scan tool probably that they advertise on TV & the Internet to make sure your mechanic isn't screwing you at least that's what they say when in reality we know that's just what the module interprets the data as. If it's a pin fitment or wiring issue they are going to be changing a lot of parts & spending a lot of $$ trying to save $$. Nice diagnosis & repair.

Good Evening Trained by Techs take care and have a great day 👍 Great tutorial thank you From Nick Ayivor from London England UK 🇬🇧

Thanks for the videos. This one was interesting to me as I have seen similar issues like this.

Very good explanation and demonstration thanks 👌👍💐

i know I'm 4 years late but The accelerator pedal did throw a code the TPS/APP refers to the throttle positioning sensor and accelerator pedal position sensor it's a 2 in one code

excellent video Carlos thanks like the PP

Good work! Thanks for sharing.

good video and great find on the bad wire. dont give up the day job for the dancing. just kidding, you got good moves. LOL

Good video!!!

Very nice video.thanks.

Thanks. that was a good diagnostic

Good fix boss. Love the content .

The best part was the song and the dancing

Very good job!!

Thanks clear explain

me paso en un nissan sentra, no aceleraba y tenia códigos del app,los, 5 voltios no los había, el problema era el switch del compresor a/c que estaba en corto circuito, ya le habian cambiado computadora y throtter body,solo esa el switch del drier 😉😉😉😃😃

Nice video ! I’m still wondering why that app sensor didn’t set a code also. Thanks for the solid content as always

Nice work

Hi there, I am getting a '00538' reference voltage-011 Open circuit error in Central electronics of my VW Polo Gt Tdi, which includes battery and charging system. The fault code stays static when the car is turned on but can be erased after turning the engine on. Checked the live data and the reference voltage is at 10.24v when the car is switched on and specifications say it should be between (11.5 to 13.5 ), but the moment the engine is turned on the reference voltage goes up to 12.4 and that's when the fault code gets erased and doesn't recurr until the car is turned off and turned on again. The air conditioner gets cut off randomly. Had sent the car to workshop they checked the wirings, fuses, climatronic, BCM and even replaced the battery, but the fault code won't go. Can you please give your valuable inputs?

Where are you getting the electric diagrams, my online Manuel's are not that nice

Wish my scan tool talked to me too! 😂 Maybe not since apparently it’s a liar! Typical Chrysler bubble gum wiring insulation.

Today I have I guess the same problem, 2005 Grand caravan, I don't have the 5 volts reference just 0.3 sometimes ground, thanks
