OK SO IM WORKING ON A 2003 TOYOTA COROLLA WITH A 1.8L ITS THROWING UP A P0420 GUYS ARE
PUTTING IN THESE SPARK PLUG NON FOULERS IT LOOKS LIKE THIS AND WHAT THEY ARE DOING IS
THERE BASICALLY SPACING OUT THE POST CATALITIC CONVERTOR DOWN STREAM 02 SENSOR THEIR PUTTING
THESE SPACERS IN AND SO I WANT TO TRY THIS UH THIS I ACTUALLY PICKED THIS UP FROM AUTOZONE
SPARK PLUG NON FOULERS 42009 AUTOZONR BY DORMAN HAD THESE COME WITH THESE CRUSH WASHERS AS
WELL BUT WHAT I HAD TO DO TO GET THE 02 SENSOR IN SO WHEN YOU GET IT IT LOOKS LIKE THAT IT
HAS A SMALL LITTLE FITTING OR HOLE I SHOULD SAY RIGHT THERE AND WHAT I HAD TO DO I HAD
TO GO TO HOME DEPOT AND GET A HALF INCH DRILL BIT AND DRILL IT OUT BECAUSE THE OXYGEN SENSOR
SNIFFER PART OF THE O2 SENSOR SO LONG THAT IT WOULD NOT FIT IN THERE WITH THIS I KNOW
THERES SOME SHORT O2 BUT EVERYBODY IVE SEEN ONLINE IS HAVING TO DRILL THESE OUT SO I JUST
GOT A HALF INCH DRILL BIT DRILLED THIS BAD BOY OUT AND THE OXYGEN SENSOR WILL GO HERE
THIS WILL GET PLUGGED INTO HERE IT WILL MAKE MORE SENSE WHEN YOU GET IN THERE SO SCREW
THOSE TWO TOGETHER THIS WILL GO INTO THE EXHAUST PIPE THE OXYGEN SENSOR WILL GO RIGHT HERE
BUT WHAT I WAS GOING TO DO WAS SPRAY PAINT THIS SECTION BLACK IM GOING TO SPRAY PAINT
IT BLACK AND THEN THROW IT INTO SOME DIRT SO IT LOOKS WEATHERED ALRIGHT SO I SPRAY PAINTED
IT ROLLED IT AROUND IN THE MUD A LITTLE BIT LET IT DRY FOR ABOUT 5 MINUTES AND THEN ILL
GO AHEAD AND INSTALL IT OK SO WERE UNDER THE CAR UNDER THE 2003 TOYOTA COROLLA 1.8L RIGHT
HERE IS THE REAR CAT REAR CAT REAR O2 SENSOR REAR OXYGEN SENSOR JUST KNOW THAT THE REAR
OR DOWNSTREAM O2 SENSOR IS BEYOND OR PAST THE CATALYTIC CONVERTER THE CATALYTIC CONVERTER
IS RIGHT HERE DOWNSTREAM OF THAT IS THE REAR O2 SENSOR SO THIS IS A 22MM RIGHTY TIGHTY
LEFTY LOOSEY BREAK THAT LOOSE WHEN YOU INSTALL THE REAR OXYGEN SENSOR I HAD TO TWIST THE
WIRE SO WHEN YOU GO TO REINSTALL IT MAKE SURE YOU TWIST UP THE WIRE A LITTLE BIT AND THEN
INTALL CAUSE IF YOU DON'T IT WILL JUST TWIST ITSELF REGULARLY WHEN YOU ARE TIGHTEN IT UP
SO YOU WANT TO PUT A LITTLE BIT OF A TWIST IN THE WIRE BEFORE YOU INSTALL IT OK SO HERES
MY OXYGEN SENSOR SPACER O2 GOT THE CRUSH WASHER ON HERE THIS IS ALSO A 22MM OK MAKE SURE THATS
TIGHT YOU DON'T HAVE TO BE SUPERMAN OR ANYTHING WHEN YOU DO IT JUST MAKE SURE ITS SNUG SO
I'M GOING TO TWIST MY 02 SENSOR UP BEFORE I ACTUALLY INSTALL IT I TWISTED IT THE WRONG
WAY SO I HAVE THE WIRES THE RIGHT WAY NOW THE OXYGEN SENSOR IS IN PLACE TIGHTEN IT UP
SNUG IT UP OK NOW THE NEXT STEP WILL BE TO GO UP TOP AND CLEAR THE P0420 DTC CODE AND
DRIVE THIS CAR AROUND AND SEE IF THIS OXYGEN SPACER TAKES CARE OF THE P0420 CODE AND I
WILL LET YO KNOW EITHER WAY GO AHEAD AND ERASE THE 420 CODE EMISSION RELATED DIAGNOSTIC INFORMATION
HAS BEEN CLEARED NOW DOUBLE CHECK THAT GO AHEAD AND START THE CAR
CHECK ENGINE LIGHT OFF NOW WE JUST NEED TO DRIVE THIS VEHICLE AROUND AND SEE IF WE CAN
GET THE COMPUTERS TO RESET ALL THE MONITORS ON THE VEHICLE AND HOPEFULLY THE CHECK ENGINE
LIGHT WILL STAY OFF THIS IS WILL A GREAT FIX IF IT ACTUALLY WORKS TO GET RID OF A P0420
BUT I WILL LET YOU KNOW 40 MILES OF DRIVING P0420 CODE DID NOT RETURN LINKS IN DESCRIPTION
