Sure

Hi

You are right. Reusing an old gasket like that is a very bad idea. You are asking for trouble. Those gaskets are meant to be compressed just once. You can end up with another trouble code for an air leak and an air leak somewhere in the induction system can be very difficult to find. He also should have put paper towel into the intake ports to prevent anything from falling down inside there.

+David Blaine Glad it helped, and you should feel good about doing it yourself. Thanks for the comment.

I'm in the process of replacing on a 2006 Sienna. Thanks for adding your experiences. The one thing I am realizing is that I need smaller hands!

Jo Daddy's Garage Do you have to drain the coolant before you begin?

Yes. Drain the coolant.

Thanks. I just look at things differently. I don't remember what I did for that clip.

Djpoints Well, honestly, I think I used a crescent wrench...

Jo Daddy's Garage Thanks! Ended up getting a big (1 1/16) combo wrench. Had just enough angle to grab just enough of the sensor. Changed both sensors and the wire harness...and after about 20 miles so far so good! One tip to other novices like myself, I think you better drain the coolant before opening the intake manifold. I didn't and coolant leaked everywhere. I imagine that's common sense in the auto mechanic's world, but figured I throw that out there. One other question Jo Daddy -- How in world did you get the passenger side bolt off the back of the plenum against the firewall? More precisely, how did you get it back on??? Unbelievably inaccessible and was by far the hardest part of this job :)

Djpoints Glad you figured it out. Definitely want to drain the coolant. That bolt was rough. I thought I went into some detail on that. I thought I unbolted the bracket from the engine, and pulled the bracket with the plenum.

Yeah, I wasn't totally sure when I started. I was hoping I wouldn't have to go so deep.

@@JoDaddysGarage how much does this cost just labor I have the sensors

I don't have a good answer for you. I did this for a friend.

Also, how long did this take you to do?

Pretty sure the hose needs to be out of the way.

I did it in about 4-6 hours I believe.

Sorry to hear that.

If I remember correctly, I got it from underneath the vehicle.

very similar to a honda accord,have to go from the bottom....

Thanks! That was easy enough however, there is another 10mm nut holding a hose bracket on the support bar for the plenum. Do they expect you to lift the entire engine out in order to release the plenum on the 2006 Sienna or am I just missing something. This is the most ridiculously engineered vehicle I've ever owned...

Thanks!!

I've seen worse.... Not sure what to tell you on the other bolt.

Dustin Nealy It solved the shift issue, and it increased gas mileage from what the owner told me.

Dustin Nealy dam this is the exact same thing that is going on with mine. a mechanic wants me to replace the whole transmission.

I had same problem on my 01 highlander, goes into limp mode and doesn't shift to 4th, I changed knock sensor wire harness, still showing knock sensor codes tho, half of my engine is running lean to which I think is causing knock sensor to show, any suggestions?

I don't really remember, but it's likely I got them from Advance Auto.

I'm getting mine (Knocks Sensor 1) from auto zone for about $155!

Not really. I just bought a brand new set of Denso knock sensors and the original Toyota wiring harness for $43 off Ebay.

@@rgt8309 Just to be clear. What you actually purchased were Chinese knock-off parts and not Toyota original. Hopefully they worked out for you and have lasted. I'm not suggesting they are inferior ... just not original.

@@PresidentGas1 No. the description said they were original Toyota parts and the label verified it. Plus, when I took out the bad ones, they matched perfectly.

Tghis video is so old. I probably got them from Advance Auto. Vehicle ran for years afterwards. They finally sold it.

I just made them tight. Didn’t check torque.

Didn't have any. I drained the antifreeze before I started removal.

Hana my dumbass didn't drain the coolant before starting. Thankfully it only entered 2 intake ports and the valves were closed. Took a windex nozzle and drained them out. Rookie mistake tho to be sure

Hmm. That is odd. Loud jerking, like won't turn at all?

Nope the starter does a hard jerk moving the engine but not turning it over. Before everything was fine.

@@claywint5977 That's really odd. There's no interaction of parts...

Sorry, I do not.

I just loaded up $300 worth of Toyota parts on amazon!!!! 2002 sienna 205K 2 knock sensors 1 harness 1 coolant hose under there Fel pro gasket set (3) in set True 1 harness for both sensors?

I believe one harness is correct.

Thank you for your video and help

I have a scanner I bought at the parts store that can clear codes.

Thanks for the answer!

you can also unhook your battery for about 5 mins and it will clear it as well

Sorry, I don't think I have access from home.

No problem

The critter did not chew it up. The wire is in a plastic sleeve. Thanks.

It was a little more complicated than I had hoped.

It took about 4.5 hours to take apart, and about 2.5 to put back together.

Very cool. I have an original 1931 Model A Tudor that I restored. It was my grandfather's car. I may do a video of that car soon.

Sorry. I do not.

What happened?

@@JoDaddysGarage not sure I put everything back together but now the coolant on the radiator is overheating.

@@marco209lodi5 Air in the system. Need to burp it. May have to jack it up on one side, and make the radiator cap the highest point. Add antifreeze.

That is not a failure. The engine computer locks out the overdrive when the knock sensors fail. This is to protect the engine from undetected engine knock until the sensors are fixed. Once the code is cleared the overdrive works again.
