That's a lot of work to replace a couple of sensors. Showing the proper removal and reinstallation of the components is so important to get everything back to its original place. As you stated leaving a ground bolt out would cause a lot of problems thanks great video Jim
I can't tell you how many times I get a car into my shop that was repaired by another shop and they left out some bolts or wiring harness holders.Thank you for your input and for watching.
I would hate to be on the receiving end of the invoice for this massive job and it’s not a job for a do it yourselfer to take on. He makes it look easy because of his expertise and knowledge.
Hey Jim, I know this was a year ago but hoping you can give me some advice. A month or so all of my coolant shot out of my engine via the water pump and my engine overheated. I let it cool down and started it back up, no issues (was worried I blew a head gasket or damaged something). I went ahead and replaced the water pump, timing belt and tensioner. A week or so later I started getting a p0330 and p0325 code "Knock sensor 1 and knock sensor 2" code at the same time. I went ahead and followed your video, replaced both knock sensors and the harness, checked the connections, protected them with dielectric grease, I cleared the codes and they came right back after going about a mile down the road. I went to some forums and some people mentioned grounds on the ECU that crack and up causing issues with the knock sensors so I took that out and reflowed the solder on those points, still the same issue. I'm at a loss of what to do at this point, I suppose I could replace my ECU but I don't know if that's going to resolve anything and I hate guessing. Any tips?
Great video. I’m about to do my own on the same vehicle so this was extremely helpful. Question though, aside from the vehicle not wanting to go into OD, would there be other issues such as engine stumble, or lugging?
Still having knock sensor bank 2 code 0330 and engine drops to limp mode. Yes had work done. Aside from sensors, throttle body gasket set, spark plugs, fuel system cleaning, valve cover gasket set…very pissed off at this point
I'm a DIYer and I did this job in 2020 on a friend's 2001 Highlander. While I was in there I replaced that large diameter coolant hose that sits in the middle of the valley because it was old and kind of hard and I didn't want it leaking later down the road. Because the valve covers were leaking some oil, I replaced the valve cover gaskets. Since the manifold was off, now was the time to get to the rear valve cover easily. I also replace the spark plugs since there was easy access to the rear three plugs. It was optional but I replaced the PCV valve since it was slightly easier to get to with everything apart. Because you have to remove the fuel injectors and rails, I took that opportunity to replace all of the rubber o-rings that seal the injectors. I also unbolted the throttle body and cleaned it. I'm not saying you need to do all these things but that's what I did. Unrelated to that job I did a timing belt job at the same time. New belt, pulleys, tensioner, water pump, cam and crank seals and engine belts.
Mine is an 03 with 360,000 kilometers just failed. Found out because my transmission wouldn't shift Into overdrive. The computer does this to minimize knock. Top gear pits the most stress on the engine.
@@sturomain would it shift up to 3rd gear only and restrict speed? Is that what not shifting into override is? I'm getting a code for knock sensor and this last described symptom. I would really appreciate any information you share to help me find the issue and fix it. Thank you!!
Yes my 03 highlander would only shift 1..2..3..relpaced knock sensors 2 of them and now it shifts perfect through all 4 gears. 2003 highlander was the last year with the 4 speed auto transmission

Excellent video Jim! Side note here you can definitely see this is not a car guy, all those leaves waiting to fall and plug the water passages 👍🇨🇦
You are right for sure. Some people never open the hood to look at anything.Thank you for your input and for watching.

Thanks for watching and your comment John. This is a little difficult for a do it yourselfers for sure.

Can't believe he didn't replace wiring harness with a new one!
Yeah I heard you should do both the knock sensor and the wire harness
I enjoy your videos, even though I don't own any of the cars you work on. 🤓

Are there any other items you should change or replace since you've taken so much apart?

Thanks Jim another great video.
Thank you Bill for your input and for watching.
Hi dont know if you monitor this recently, but question do you need to drain both radiator and block of coolant?
Great video Jim.
I appreciate you stopping by and watching.
You're great, I love it ! Thanks!!
Great video sharing
Thank you for watching.
Thank you beautiful job
What brand did you use
Good luck 👍
Thanks for stopping by
JIM body, you has to improve the lights.
Thank you for your input and for watching.
What is the mileage of the car at the time of failure? Just curious to know how long they last.

Not good, torquing????
