I just bought a 03 is300 150K miles
so far I replaced the valve cover gasket, o2 sensor, spark plugs /w wires, front shocks and brakes
before I did the shocks and brakes the abs light would flash but would go out if I turned my key from the on position to off then back on, but now it stays on with no flashing I believe it has something to do with the sensor in the wheel well. My CEL is on and the code given was p0441
Any ideas on what is causing the issues

 

The Trac control light is just to get your attention. It has been turned off. The code is having to do with your evap system/emissions. Check vsv, gas cap, fuel pressure switch, cracked hoses around intake and throttle body. Subscribe to my post just below yours about my p0446 code. Our codes are very similar and any response to mine could help you
