I have a 2000 RX300. I have an odd knock sensor problem. The knock sensors have been replaced (twice), but the knock sensor code came back. When it comes on, it goes into limp mode...if I turn the car off, wait 30 seconds, restart, limp mode goes away. The check engine light stays on...but the next time it throws a code, back to limp mode.
Any suggestions would be helpful.
Thank you
Jim
