Hi everyone. I need help. I have a 99 RX300. The Track Off and CEL lights are on. Sometimes the lights go off, sometimes just the CEL comes on, but usually it's both. Now, if I start the car and the lights come on, the transmission will not shift beyond 60mph. The RPM revs at 4,000. If I'm driving 60mps(ish) and the warning lights come on then I don't have any issues with the transmission.
Went to AutoZone for code readout and got P0330 - Knock Sensors.
Called Lexus and got: Knock Sensors +labor $1150, Wire Harness/Gaskets $150, Platinum Spark Plugs $275. UGH!
Tried looking at the air filter but didn't see any hose at all. Don't laugh, but should I see this from under the car? Because I only looked around from under the hood - while on my lunchbreak.
How do I know if the Knock Sensors are truly bad, or if there's a kink in the computer?
