* This is for a matrix xrs… but im guessing its the same for a corolla…
Well I’ve been having a CEL for some time now… And today I finally got a brand new oxygen sensor from Toyota. It was a really easy install, about 5 minutes I would say.
First jack up your car
Then disconnect your Battery
On the passenger side… flip over the mat, right under the shifter/center console you should see this
and disconnect it
while you are up there just go ahead and push the rubber molding down so it can be easier to pull from underneath.
Now comes the dirty part… get underneath your car and carefully unscrew the old sensor
and this is what that old/damaged sucker should look like when compared with the new one
remember to remove the clear plastic protector and carefully screw the new sensor back on. It should come with some grease or some anti-metal lock grease.
Make sure it’s really tight… and make sure you correctly insert the rubber protector/molding back in the hole under the passengers side mat.
and put the mat back together just like it was…
Re- connect your battery and turn on your car
Check for any leaks
Lower it and run it around your neighborhood for about 5 minutes to check if any CEL pops back on
after it passes that test… Connect a code reader to check your results…
and your DONE!!!
