Engine Mechanical problem
1992 Toyota Camry 6 cyl Front Wheel Drive Automatic 226700 miles
I have a 1992 V6 XLE Toyota Camry. I have found that trouble codes 12 and 28 flashed when I diagnosed my check engine light. I know from looking on line that trouble code 12 is the knock sensor signal and code 28 is the No. 2 Oxygen sensor signal. What I need to know is what specifically might need to be repaired based on this information?
