LS400 Knock sensors 

I'm glad you didnt say driver's side and passenger side Kelvin, since the steering wheel is on the wrong side haha...I'm still trying to catch up on your vids but decided to jump ahead to the finish...Great job as usual !!

Knock sensors and starters are always FUN to replace on the 1-3uz's..pain in the ass if u ask me. Good opportunity to clean under the intake and check for bad vaccumm lines. Cheers

Awesome vide. Is there any way to test the knock sensors prior to buttoning up the engine?

Do you just use another length of wire connected to the multimeter for testing continuity to ecu? ( for reference, the yellow wire around 7:20)

I didn't hear you mention it but are the 3uz and 1uz knock sensors the same? I have seen conflicting information online that late 1uz vvti knock sensor are the same as early 3uz vvti knock sensors.

You think an unrelated constant misfire could cause a knock code to trigger? Cars got a dead fuel injector so I’m assuming that’s why it’s triggering a knock code

I know is possible you know about this but they are known to have problems on the insulation of the wires to shielding to ground I have see this problem a lot causing ecm damage

I cut into the loom of my 1JZGTE years ago when running an AFC2. It wanted a knock input for displaying knock I'm assuming. Not long after I had error 52 knock code. Long story short I had to run the engine on one knock sensor, split wiring from one and put two inputs to ECU. Do you think it's worth going back and adding factory style shielded wiring ? as I think simply cutting into the knock wires caused the issue. I just think it's too much of a coincidence that I splice into the wires and not long after get issues. Another great vid btw.

Why are gen2 3uz have 2 wires per knock sensor?, is the other one is a simple ground?. If so, are they interchangeable with a simple earthing the other wire?

informative video again kelvin. Hey can the knock sensors be wired in to my link G3 cheers Ants

Have a UCF10. Had caps replaced by LSCowboy. Replaced all S/plugs and Wires. Car idles smooth on 95 Octane. But........ Car when overtaking under load at say 75mph suddenly jerks. Same happens if I use Kickdown. Using 98ron in France as no 95ron Only place I can do this speed. No fault codes showing on OBD1. About to change the upstream O2 sensors. Could it be the knock sensors? No check engine light appears. Feel could be running lean at speed (slight engine noise change?) Changed Fuel filter, has original MAF sensor. New coil, the easy one to replace, not the other. Damned if I know why it jerks and I have to fall back. Runs beautifully all other times. Passes Omissions - Your wildest guess please

Do i have to take the intake out on 98-00 (ucf20) to do the knock sensor ?

I have a 1992 sc400 throwing a P0325 Knock sensor 1 Circuit 1 engine code; I'm wondering which brand knock sensor to use as a replacement. A link to a reliable and high quality replacement part would be highly appreciated.. Cheers.

If you swap the plugs with knock sensor #1 and #2 will that give you codes 52 and 55? Also, what if you get knock sensor replacements that fit but have different plugs? Will it still work if you hard wire them?

Average price to convert manual hilux surf to the 1uz?
