2000 Lexus Es300 Engine & Trac Off Lights On

[Stephen8229]

Hi everyone. These two lights have been on for over 6 months now. Car runs fine (126,000 miles), but I was wondering if this was an easy (inexpensive) fix?

Midas Muffler did a quick code check and came up with this @ code check:

Knock Sensor 2, Circuit Malfunction, (bank 2)

Lexus told me that if the engine light isn't blinking, that it's probably nothing serious, and the light is steady. So is the 'Trac Off' light.

Can anyone shed some light on these codes?

Thanks for your time!

I replaced my Knock Sensor it took 6-9 Hours. Here is the link

Knock sensor isn't a disabling condition, but when it's out, the computer does things to prevent knocking, like enriching the fuel mix, advancing the timing, and sometimes turn off overdrive; overall reduces effiency. Usually the problem is the wiring harness, but in my case, both knock sensors were toasted as well when I got to them.
