Lexus ES300 Posted February 10, 2008 Share Posted February 10, 2008 2002 Lexus ES300. Check engine is on, code is P0420. Idle is too low, 300-400 rpm and after 5 minutes ECU throws ABS, TC and VSC. Any advice? Quote Link to comment Share on other sites More sharing options...
djspawn00 Posted February 10, 2008 Share Posted February 10, 2008 You probably need a new catalytic converter which still may be under warranty! Quote Link to comment Share on other sites More sharing options...
Lexus ES300 Posted February 10, 2008 Author Share Posted February 10, 2008 What about post cat O2-s? Quote Link to comment Share on other sites More sharing options...
djspawn00 Posted February 10, 2008 Share Posted February 10, 2008 You can check the sensor and see if its pulling the right numbers but in my limited experience the sensor is working thus detecting the cat failure. How many miles do you have? Quote Link to comment Share on other sites More sharing options...
