96 Camry LE V6 - P0330 - knock sensor 2 circuit malfunction bank 2
Over the last couple weeks I have been getting a P0330 error - knock sensor 2 - circuit malfunction bank 2 and it reappears 5 to 10 minutes after I clear it with my OBD2 scanner. The CE light comes on and it doesn't seem to correlate to any speed or RPM...
A little background. The son is now the primary driver of our old 96 Camry LE V6 (that may the the problem lol), which has 120,000 miles and is well maintained by myself. I recently change plugs, wires, filters and 2 of the 3 O2 sensors (the one downstream and one of the upstream ones) due to poor gas mileage. The mileage did improve and plan to change the other O2 sensor shortly. (I have 3 Toyotas with the same 1MZFE engine and thought I had replaced one already but it was on the Sienna). Changed out most of the exhaust system last summer except the cat converter. Replaced the header pipes because the flex pipe failed, and replaced the muffle and tail pipe with a Cherry Bomb or something similar making it overly loud.. KIDS!!
He did have a mishap in December, over the hill and clipped a tree. Had to replace the front passenger side door with a used one and full the wrinkle out of the roof. Looks like hell but I don't have to drive it!! lol Also had to put the exhaust system back together, had pulled a slip joint apart.
Also there is a slight hesatation when accelerating through 3,500 - 4,000 rpm, in second gear only.
So the question is... Does this error mean that the KS has failed? and if so where is it located and how easy is it to replace? Have a short window since it has to be inspected soon and they will not pass it with any error codes present.
Any help hould be greatly appreciated.
