Nice job Matt, like your meticulous testing process, a much more serious approach than just swapping parts off the top of one's head.

Excellent video with test diagnisis,not just a parts changer untill you strike lucky. Top work

Good solid workflow. Learned something today thanks. That variable resistor box is a good option for validating values (or lack of)

[@MarkDaviesThailand]

Nice diagnosis. Thanks Matt.

Nice work Matt 👍

amazing very cleaver way of testing I have some questions I would like to know your answer what if we facing more than two wires oxgen sensor how I'm going to test it using the decade resistors box can we use it for testing airbags sensors thank you for sharing.

Proper job done 👍👍

Well done Sherlock! Great diagnosing easy when your in the know,outstanding sir 💯👈🏻🫵🏻

Any ideaa where I can buy that little resistor box, could we of pulled the voltage down using a test light? Thanks

[@mechanicmatt871]

Yes a test light works, you will see a reaction on the he live data on the scan tool. Just isn't able to adjust the resistance to where you want it. You can buy a decade box on eBay mate, there are other makes that are cheaper that work fine too.

Always worry me fitting aftermarket sensor as had so many failed or car ecu not like them. However I bet a oem for that car would have been £200 so customer would want aftermarket

MAT, YOU AMAZE ME EVERY TIME ,,, NOW CAN I USE A DECKED BOX TO CHECK A APP SENSOR , SO I CAN KNOW IF IT IS THE SENSOR THAT IS BAD AND NOT THE CIRCUIT PLEASE REPLY NEED YOUR HELP THANKS PLEASE ?????????????????????????????????????????????????????????????????????????????????????

[@mechanicmatt871]

Hi, that one would be a little different, due to it having two position sensors in the accelerator pedal position sensor. Usually one signal it double the other signal voltage. If it was me doing it, I would use a scan tool to look for a change when I press the pedal. If no change, I would check the five volt power and grounds at the pedal, then see what the voltages are on the two signal wires. If one was missing a signal voltage, I would maybe just use a test light from battery positive to bring the signal up, and see if the scan tool love data changes. You would need to know if the good signal went from 0.5 to 2.2 or if it was 1.0 to 4.5 volt range, for example if you were getting the lower range but not the higher range, you may be able use the decade box to put double the voltage into the other signal wire, by going between the five volt supply and the signal wires and changing the resistance settings until the voltage is where you need it, then seeing if the fault code cleared. I think in this case the test light method would be easier like scanner danner does. This may not come across clearly in a text message. Thanks for watching

@@mechanicmatt871 THE CODE I AM CHASING IS P2138 ON A 2013 BUICK LACROSSE WITH LOW POWER AND WON'T REV ABOVE 3000 RPM IN PARK . AND WHEN DRIVING IT'S LIKE IT'S STUCK IN A LOWER GEAR . THIS IS THE SECOND APP SENSOR THAT WAS THROWN AT THE CAR BY THE TIME I GOT THEIR . HOW WOULD YOU ATTACK THIS CAR'S PROBLEM . 🤔🤔🤔🙏

Exhaust Gas Temperature (EGT) pre-catalyst Exhaust Gas Temperature (EGT) post-catalyst How do they calculate the temperature? Because one calculates very quickly and the other calculates much more slowly. And lags behind. Volvo xc 60 2.0 disiel D4 engine
