blinking

According to the Lexus manual...regular blinking means OK..error codes are indicated by alternating flashes (e.g. 5, pause, 2 would be error code 52)...I've got a bad rear o2 sensor and my trac doesn't work: ck engine and Trac lights are on and I get the 52 error code...

so...it doesn't sound like o2 to me

BTW you can clear the ECU temporarily by disconnectintg the battery or removing CB13 temparily to reset the ECU..it'll tahe a while (100 miles?) to reregister o2 failure and shut down Trac
