200 miles into a new SC with no knock

[sleepydad]

And now all of a sudden I start getting knock codes every couple of miles

Are you running high octane and or any fueling upgrades?

Or intake mods? I was getting some knocking when I first installed mine with the deck plate. Went back to the stock air box and has been fine ever since. Definitely noticed a loss in power, but max hp was never my goal. Just wanted to get back the power I lost with lift, armor and tires. Have that now and then some. Very happy.

I only run 93 from a local bp station

The only thing I did was replace the inline fuel filter

I did install the 2.2 pulley right of the get go, swapped it back to stock last nite. No difference.

I did try IK22 after the horror started. No difference.

Seems like 2000 rpms is the magic spot, I can’t hear anything I can do it in the driveway with hood up watching torquepro and manually operating the throttle.

I ordered a couple OEM knock sensors and the wire harness last nite... should be a fun weekend project. I will need some me gaskets as well.

Nope the intake, Bone stock.

I ended up running a water meth injection system from Snow

dude! you should use distilled water. snow is all full of dirt and outside stuff.

how many miles are on your truck?
my knock sensor went out around 220k - but supercharger was on for over a year.

178K

my plan

take the charger off and put the stock intake back on

burn up some gas and see if I continue to get the bank 2, sensor 2 knock code. if I still get it... sensors and wire harness. drive it around and make sure I don't get that code.

if it goes away... that is a harder call I guess. I was hoping to do headers for sure then 7th if needed. I would try the headers first to see if does anything.

yes I agree it might just be the knock sensor/wire harness.

That moment when you hear engine knocking... NSFW! Lol

I bet it's one of the sensors, the harness or both.

Don't the knock sensors only kick in at 3k+ anyway?

Also, it's possible the engine was still adjusting those first 200 miles. How about going stock pulley then pulling the battery for 20 min, then giving the truck a chance to relearn?

I pulled the battery and let it sit overnight, I’m lazy and slow. Then I replaced the 2.2 pulley with the stock pulley. Knock code right away, @ 2000k rpm.

Honestly I have never seen any official Toyota information regarding knock sensor RPM ranges. I have seen all kinds of official “internet” ranges tossed out so...

Higher octane, lower compression, retatard timing, or sensor failure.

It's your sensor and/or wiring harness. The supercharger can cause pinging/knocking but not enough to throw a code. The code means that the sensor is out of range or there's a signal issue to the ECU, a normal functioning knock sensor will just pull timing advance. It's a common problem with these ageing engines.

I’m almost done putting the stock intake back on. Will see if I continue to get codes with it. If I do and actually I hope I do, it means I know what needs to happen. I already ordered the Toyota denso sensors and wire harness. Ouch. But for this I think it’s worth it for sure.

If I don’t get codes with the stock intake then I will have to go down the urd fuel mod path for certain. Regardless will end up doing knockers.

I should have just stuck to stock... now I want to go faster.

confirmed for now

I pulled the charger off... put the stock intake back on and went for a drive, bang same P0330 sensor 2 bank 2

had I just read the doco for the code... I would have maybe not blamed the charger. it for sure pulls timing @ 2000 rpms once the code blows.

thanks for your help. internet points for everybody!

note: sorry coho51 I just could not resit... blame it on years and years of reddit in my blood.
