engine codes

You need to change your inverter coolant pump to get the red car off of the MFD center display The pump is behind the driver side headlight if you put your hand on it with the car ready it should be humming and you should see a little bit of movement in the reservoir between the engine and the inverter that says hybrid synergy drive If you see no movement but you feel vibration probably time for an inverter pump by the real Toyota one so you don't do it again anytime soon I know the $39 one seems tempting but they fail as fast as you install them so be ready to do it often The PO420 if you have a missions in your state then you may need a spacer with a swivel made out of stainless steel that has a piece of converter material in the end of it they make these they're about $18 that may get the light off for you If not you're buying a very expensive catalytic converter like 12 or $1,400 seriously where I live I don't have to pass emissions so we don't have to do anything with that your city or town may be different

 

In Florida I don't think you have anything down there You can do anything you want with your vehicle so you can just leave that light alone I have one or two here that I've had that code for 5 years they still get excellent gas mileage and everything this has nothing to do with anything except the catalyst being below threshold of some computer setting that is probably set too tight to begin with anyway It's nothing we can change AE11 Corollas had this exact same problem more or less it was an ACDelco firmware problem for the computer between the 2 02 sensors
