For the last week, the check engine light has been going on and off in my ‘99 ES300. Other than the warning light, the car has been performing normally. I took it to the dealer and they told me that the knock sensor is malfunctioning and that the engine is not getting the proper air/fuel mixture. They said it would be around $950 to replace. I realize that dealers’ are usually more expensive. Does anyone know if this type of repair must be done at the dealer? Also, can I get away with driving it for a little while without causing further damage/trouble?
Drop by a local AutoZone, Advance Auto, Checkers, etc. and have them check for codes. They will do this for you free. Post the exact results back here for further discussion and hold off on the 950 at this point.
From the sound of it there may be multiple codes and/or repairs, but a second opinion won’t hurt. And the best part; it’s free here too.
I agree with OK. Let’s start with a second opinion.
