"Check the tires once a month." Right! Like anyone does that. I use my MaxiTPMS TS401 from time to time to check my 2020 RAV4 and my 06 Nissan Frontier. Yes I've replaced the 4 sensors in the 06 Frontier. Just before I retired April 1, 2016, the left front sensor would turn on the light. Usually on a Saturday morning when it was cool/cold outside. Borrowed the shop tester on Monday, sensor read normal, so I'd reset the system. This happened twice. so, I adjusted all 4 tires to read 40 PSI, and all 4 sensors read about 2 PSI lower. Borrowed the tester again on a Friday. Sat morning I gauge checked the tire pressure. Still at 40 PSI. Turn on ignition switch and BOOM! Light stayed on. Three sensors read about 2 PSI lower than gauge, left front read 5 PSI lower than gauge. Cool morning, "intermittent problem," 10 year old vehicle and it's TPM sensors. One new Nissan sensor, all's well in Nissan land. Two weeks later, same problem. Used my previous procedure, right front's bad. Bought 3 new Nissan sensors, no more problems. It's been almost 5 years now, still working well. Thanks for your videos.

My 2020 RAV4 gets a lot of "around town" driving. Then I put it on the freeway, cruise control on, 70 mph for several miles, then drive it back at the same speed. Not only the combustion chambers, but the PCV system, engine oil, trans fluid and more get good and hot and helps to eliminate the moisture that gets into those fluids. The next time it's driven, it's like a young kid full of energy instead of an old person who can't move well. Also, that very slight tip-in hesitation is gone! The vehicle has "less than" 9000 miles. Not a typo! And yes I'm retired 6 years now but still work on my own vehicles. I may do overkill on preventative maintenance, but the proof is in the vehicles operation. They run great! More important. "You take care of and maintain your vehicle, it'll take care of you!"
Thank you for this video. Hope the new building is coming along well!

Fuel trims can throw you. For example. Watch when your LFT reads 12.5 and your SFT reads -10.5. This can confuse people, but actually, your TOTAL fuel trim is +2.0 or 2.0. The short trim is removing fuel, but the LFT is taking its time to reduce. I've seen this after a repair. The fix was to reset the fuel trims and watch. The engine has about 40K on it and the SFT reads from -7% to +7%, and it stays that way. There's other scenario's, and only by learning how SFT and LFT work with the AFR sensors is it understood. I saw one Ford V10 van that both banks LFT and SFT reading at +25% each for a combined TOTAL Fuel Trim of 50% each bank. This was at idle. As the throttle was opened slowly to 2000 RPM's, LFT's and SFT's settled down with LFT's approximately between 6 to 8% and SFT's approximately between -7 to +7%. At idle, the van shook so bad, I thought the ladders would fall from their roof racks. The cause was a tear in the PCV hose on the bottom of the hose near the port on the throttle body. Ford had an upgrade for this with a thicker hose material. With the the new hose installed, fuel trims came down, no more shaking and all was well in Ford land. The tear wasn't big, only about 1 inch long, but the engine heat and vacuum caused the tear to turn inward toward the inside of the hose. It was that thin! A tech learning about fuel trims needs to work with vehicles that are running good to get a baseline understanding of that system. Disconnect then reconnect a small vacuum hose and watch the readings. I had to learn fuel trims AND the Ford WDS diagnostic system we had before we got the IDS which I understand is still in use. Thankyou for this video.

I have a Matco code reader, an Actron code reader and a little more, and a Matco MaxMe diagnostic tool.
This XTool looks GREAT! It obviously looks like it will do much more than the MaxMe.
The two code readers I have were used for monitor checks and any pending, current or history codes back when I was smog testing our fleet vehicles. That worked out great back then. This machine shows how far these Android Diagnostic Tools have come.
Also it's much less expensive than Snap On, Matco, Mac, Autel, Bosch and others. What kind of customer service do they have if there's a problem with the tester? What kind of warranty do they have for the tester?
With yearly updates at $99.00 after the three year free updates, THAT'S CHEAP! Hopefully that covers Domestic, Asian and European.
TPMS has reset only, and you need a tester like Bartec to test the sensors.

I have removed dash assemblies from Fords, GM's, Kia, and Nissan, but not on Toyota's.
When you remove what is needed to get to the level AMD is at, you sit back and look at it, sometimes shaking your head.
When I was finishing a Ford Truck at work, someone asked me, "would you do it again?" To which I said, "Yes....Just not tomorrow or next week!"
I learned to take LOTS of pictures during teardown, and I used Green (body shop type) masking tape to identify which connectors plugged into each other and what hardware and other fasteners held assemblies together. Looks like a lot of work during teardown, made life MUCH easier during reassembly.
Thank you for this video.
