There's some pretty easy diagnostics to find out what this is, but the bottom line anyway will be replace B1 and B2 knock sensors, plus the short wiring harness.

It's buried in the V between the two cylinder banks. Remove intake manifold after removing plenum. There are two sensors, one on each bank. Could actually be in the wiring to the sensor, of course.

If you DIY, get your parts from garys@toyotaofnewnan.com. Thirty% off MSRP to TN members.

I think that your ECU should go into fail-safe mode and be very conservative on spark advance. This will prevent engine damage, usually at a cost to fuel economy. If you want to add suspenders to that belt, you could use premium fuel until fixed.

Oh, change the coolant bypass hose while in there. Give you a little more room to work, and avoid wanting to shoot self if it started leaking in a year or two or...ever.

Listen to any other advice from Gary.
