What is the malfunction code the repair shop had for the knock sensor's..
You got a very expensive quote was this the dealer's quote.
Good please do that .
Was ir Pep Boys with the quote.
Okay good .
Please get me the actual code as many issue that are very simula to yours can be different causes .
When you have a knock sensor issue this can cause you no top gear .
and is normal for the VSC and $WD light to come on ,when you have a engine malfunction it will go into safe mode and deactivate the use of the VSC and 4WD. this is normal does not mean you have a problem with these system .
Even a O2 sensor malfunction will cause the VSC light to come on.
So lets wait for the actual code that has been stored in your ECM.
Okay thank you .
These codes will trip the other warning lights .
The knock sensors 1 and 2 have an open circuit or the sensor itself is bad and needs replacing .
This can be repaired by any toyota repair shop or dealer .
