1996 Toyota Avalon Knock Sensor

Posted in Crank, Oil and Piston
  • My beaterific 1996 Toyota Avalon has failed emissions testing. It has recently undergone mass-air-flow sensor replacement along with plugs and wires, but the technicain at the garage seemed to indicate that the code shows a bad knock sensor. It’s $670 to replace and the quote shows only one sensor priced at 275. I’m seeing some things online that suggest the 96 avalon has two sensors under the intake and they run about 170 each. Anyone know if there are one or two knock sensors? If I order the parts and replace the sensors, is that likely to clear the emissions testing, or is this something I should leave to the technicians? (My mortgage is due so I’d rather save as much as possible, and I’m about to drive this thing off a cliff, so any help is appreciated)

      There are 2 and they are very involved. The sensors may not be bad though. If the “hear” a knock, they kick over indicating possible low combustion due to needing a tune up, to bad gas that has low octane. Try and octane booster to see if the knock indicator will go off.
