I was a motor mechanic in the 1960's, early 70's then moved into the aviation industry so I missed the whole shift from simple mechanical linkage operation to electronic sensors, ECU's and actuators. I'm retired now and have just started working on my own cars again, upgraded my tool kit, bought an OBDII scanner, and am re-training myself to understand the tangle of pipes, tubes, sensors and wires that are under the bonnet of modern cars.

This is pure gold, thanks for taking the trouble to make and upload this. Just one thing I would like to add, regarding fault-finding: very frequently the sensor isn't actually at fault. Instead, it's a connector somewhere between the sensor and the engine management computer. Replacing the sensor will often clear the fault because a new sensor comes with a new connector. Still, I always suggest, before spending time and money replacing a sensor believed at fault, separate connectors, spray with contact cleaner, re-assemble, re-test. I have been repairing electronics systems for 4 decades and have more experience of failed (or intermittent, even worse) connectors than I would wish on anyone!

[@d4a]

Very sane advice! I wish I had mentioned it.

[@moabfool]

Even worse, my Idle Air Solenoid was bad. My truck would die when I'd shift from forward to reverse or just as I'd leave a stop light. It was intermittent and incredibly annoying. I finally decided that it was the Idle Air Solenoid, which it was. And it wasn't. I had removed it to clean the air passage in the throttle body. When I reinstalled it I bent one of the terminals. It was a simple issue, but since I had already bought a replacement I just installed the new one. The truck ran great after that.

[@allenashkar3748]

Well done! This demonstrates how complicated engines are. I was driving once on the highway and suddenly the speed dropped from 110 KM/h to 50 KM/h. The vehicle wouldn't accept speeds of over 60 KM/h. From idle, when I try to accelerate, the engine would shutdown. So I took it to an automotive shop and they used the latest diagnosis tools and they couldn't find the problem. They said the transmission (automatic) needs to be replaced, and they said that they see a misfiring on one of the cylinders. They charged me $200 for their diagnosis without finding out the actual problem. They failed to check the very basic components, which I then did myself, and I am not a mechanic, and found the engine air filter ripped. I went and replaced the air filter with a FRAM filter that cost me $11 at Walmart and everything was fixed. Obviously, the ripped air filter allowed large air mass to flow in and the ECU couldn't accommodate the high signal reading of the MAF sensor, hence it was shutting down the engine. This is one useful example of this great video of what sensors do and how important they are to running the engine. PS. that vehicle I had was a Nissan Pathfinder 2000 SE 4X4 model.

[@kootnygreen]

I once had a car do that from a plugged catalytic converter. I would suspect the ripped air filter was caused at the dealership. This would only allow a little extra air because it is no longer restricted by a filter. The throttle body regulates airflow, not the filter. Your throttle body might need to be cleaned, maybe check fuel injectors and fuel pump/ filter. Try some Lucas trans fix for the transmission if it seems to perform poorly.

I started a fulltime automotive job back in the 70's and seen the advancement of electronic engine control over the years until I retired (ASE Master Tech) in 2017. When I started, Chrysler is starting to add electronic ignition on their vehicles. Then GM and Ford fallowed. Then they started making computer controlled carburetors. Oxygen sensor was called Lambda then. European and Asian were using CIS (Continuous Injection System). The big three were using TBIs ( Throttle Body Injection). Then non-sequential (gang bang) port fuel injection followed by port sequential fuel injection. The ECM (Electronic Control module) was changed to PCM (Powertrain Control Module) when the module is controlling the engine and transmission. Now they have Direct Fuel Injection but it wasn't perfect because of the carbon build up in the valve seat causing driveability problems. They had to go back and add a port fuel injection to wash the carbon build up. I've learned that even you memorized all the function of the sensors and know how to use the scanner, there is a time that a problem exist but no DTC. Also start your troubleshooting first by visual inspection. Sometimes you can fix the problem without even connecting the scanner. Don't make a mistake by thinking its an electronic problem right away. Nice presentation.

Oh. My. 😮. You just might have literally saved my life by creating this video and sharing it with the world. I'm not even exaggerating. Somebody hateful recently vandalized my vehicle from the inside out with the intention of disrupting its functioning but in a manner so that the effects are delayed enough to allow a separation of time between their actions and consequences so as to appear as having no part in the vehicle's malfunctioning (whew, long sentence, sorry). I didn't have enough of a global understanding of the engine operation to be able to explain the situation to anybody else....but I really think I might be able to now that I watched your video! Omg thank you for this info, presented the way you did!

Outstanding video mate. Most of these sensors were a mystery for me and now it all makes sense.

This is a hell of a video, compact, precise, clear, etc. I don't even know anything about cars but to put gas and put it on D. Great Job.

[@paigecollyar9098]

Thank you for your given information of knowledge. Perfect to watch, over and over to be able to learn a little more without having to go into serious debt by going to a technical college!! I swear if I had the given availability to do so I'd jump at the chance in a heartbeat.

Brilliant! Thank you for taking the time to educate us. I knew the majority, not all. Putting a video together like this, is very helpful.

[@aqwaaqwa7819]

Extremely good. Impeccable. Comprehensive yet simple. Well organised. Well done.
