2011 GX460 Ghost Problem-Need Help

Recommended Posts

Hoping to get some help. It started with a car wash which blew the EFI fuse. When fuse was replaced, car started and runs fine but my check engine light is on, ESS Off indicator is illuminated and the 4-Lo light is quick flashing. It's throwing a bank 2 sensor 1 O2 sensor code P0051. Replaced both bank 1 and 2 sensors with DENSO OEM sensors. Still the same lights. I tried power reset of the ECM several times with no lasting effect. Lights would go out for a few miles then return. Any ideas?
