@Toyota Maintenance. Thank you Professor Peter for today's lesson. I now know how and what to check coming this spring since I don't have a garage and it's very cold where I'm located. Hope you and your family stay safe and well.
The little two wire device in the MAF is the air temp sensor. It doesn't need cleaning at all really. The circle in the middle of the maf redirects a small amount of air flow up into the housing a little further and it only samples that air. The reason they do this is that less dirt gets into the sensor itself. Many other MAF's have the sensor element in direct air flow but it is much more likely for it to get dirty
I would love to see more vehicles of all brands take this lead as well. I would hope the manufacturer's would keep the buyer and future mechanics in mind when designing their vehicles.. Make them more easy to work on for at least routine maintenance. Thanks for sharing!
Hey Peter! I’ve been watching your videos and love your content. I wanted to ask where you are located. I would like to get my truck inspected by you. It’s a 2000 Tacoma. Where is your shop?
Very good my friend , but is the part again that you are looking at on the MAF sensor the temperature sensor not the hot wire and cold wire ? I believe they are inside down in the sensor . ? I think your killing too many birds and some are flying away on you , Lol..
I have a 2011 Toyota Prius and it is not easy, as you say, master, I already changed the maf sensor and the code continues, no longer what to do because the engine light does not show on the dashboard, but the code continues permanently, I already drove it away and keep the code
Took my 2009 prius for oil change and they gave it back to me with engine light on. The cel light was on. They said car would not drive while running, they also said engine was running poorly. So when they found code p0101 they did more inspection. Checked and moved harness and noted loss of engine powers fault. Removed sensor, cleaned and test voltage with sensor pulling good voltage. Used another sensor from used car and sensor was reading the same. They saw rodent feces and probably rodent damage to the harness. Resseted and manipulated harness and pulled error code again. Resetted 3rd time time and noting no faults or problems.. They recommended more electrical testing?? They said if issued further happens...possible harness issue
I have a 2014 Toyota Prius 1.8 L 4-cylinder (2ZR-FXE) with 44K miles. I tried to clean the Throttle Body on the vehicle and when I pushed down on the Throttle/Butterfly Valve it did not move. I’m trying to determine if I have to disconnect the battery or remove the electrical wires going into the Throttle Body to allow me to open the Throttle/Butterfly Valve. Any information and/or procedures that you could provide on this matter would be greatly appreciated.
Many modern vehicles have very complicated internal mapping in the ECU that will slowly trim out small issues with the MAF sensor. It uses the oxygen sensors to read the actual AF ratio and compares that to what it thinks the AF ratio should be based on the calculations it performs for engine load etc. As the MAF reading slowly changes over time, the ECU compensates for this. Of course if the MAF is out very much then it will throw codes and any further than that it will bring performance degradation etc. There is some crazy shit happening in ECU's of modern vehicles
My footwell doesn't get any heat ('06 4runner). The windshield and dash work great. What might be the issue? Thanks, it's winter in Upstate NY and my feet always freeze while driving.
@@peterrudy9207 I would think if it were clogged the heat wouldn't work at all. I'm wondering if there's a "footwell only" fan that is broken or not getting power.
@@peterrudy9207 When I bought it I flushed out the green fluid and replaced with Toyota coolant. During the process I also changed out the thermo with an OEM. My BlueDriver won't diagnose the HVAC or the truck doesn't supply the info.
It's worth mentioning to remove the throttle body to clean it. There are dozens of RUclips videos of guys cleaning the throttle body while still bolted onto the intake, which forces the contaminates into the engine... Not good.
Get rid of the Subaru banner and don’t work on them again , they are horrible to work on ....stick with just Toyota, much easyer to fix and you’ll have tons of returning customers...You service Subaru you’ll have millions of costumers and your shop is not big enough to tackle that.

Peter, After 175,000 miles they are due for a good cleaning.
Very useful tip for me, personally. My 2008 only has 77,000 miles on it, but I will go check mine tomorrow to make sure it’s clean. Love your channel.
Always good to see your videos.
I would love to see more vehicles of all brands take this lead as well. I would hope the manufacturer's would keep the buyer and future mechanics in mind when designing their vehicles.. Make them more easy to work on for at least routine maintenance. Thanks for sharing!
Thank yo sir! Your channel is the best I’ve found! Excellent content!
Great video lesson
Great man.please continue with Toyota Prius hybrid.i want to learn hybrid new technology
You Are the Best! My friend!
Thank you Peter. Good stuff. You D man.
Thanks Peter.
Thank you!

i give you 2 thumbs-up!!!!!!!!!!!

Hej.
Jag är mycket glod när du arbeta med prius🌷🌷🌷🌷
I cleaned my MAF and TB at 100k miles (non-Toyota car). It didn't seem to make much difference in engine performance, as it was not that dirty

Is it recommended that we clean the MAP sensor (01 Civic Ex)?

Clogged heater core ? I grew up in Horseheads NY .

@@peterp.6249 Yes , some lever is not opening ? for the coolant to flow . Thermostat or radiator to be flushed ?

@@peterp.6249 Check out Scotty Kilmer - RUclips Mechanic . Just watched him on this issue . Said it could be a heater control module ?
You just killed three bears with one pic-a-nic basket 🧺
What a coincidence. I just got home and bought MAF and throttle cleaner with plans to clean them both!
It's worth mentioning to remove the throttle body to clean it. There are dozens of RUclips videos of guys cleaning the throttle body while still bolted onto the intake, which forces the contaminates into the engine... Not good.
I’m actually pro-bird, but I take your point.
I would have changed the air filter and cleaned out the air filter compartment .
