late afternoon right after returning from office i restarted my mission that was failed the other day. to get the o2 sensor changed!
i got my tools ready. socket wrench, swivel connector, small tip screwdriver, black tapes, flexible mechanic magnet, and last but not least the o2 sensor socket.
top part removals were easy. engine cover and pollen filter box were first removed. this step is done in order to easily get access to the old sensor.
the o2 sensor is connected in 2 ways. one to the cat the other to the connector. first unplug the connector side.
then move to the cat edge. try to fit in the special socket to the sensor. need to do from the top of the sensor not from the side. otherwise it wont fit. i could not see the sensor, all based on hand sense only.
after the socket fits into the sensor, then connect the swivel connector, then get a bar connector and link it to the swivel, on top of the bar tuck in the wrench itself. then start rotate anti clockwise to loosen the o2 sensor. one or two times rotation is enough, the sensor is loose, unplug the bar connector and rotate out by hand.
the result. old sensor is on the left, and new one is on the right.
then it's time to fit in the new sensor. using hand, patiently rotate the new sensor into it's location clockwise. why patiently? because of the sensor wire elasticity, it will rotate back the sensor against our way. tips, right hand rotate the sensor in, left hand concurrently rotate the above wire.
when it feels like the sensor is already firm and in it's position, use special socket to tighten it. do not over tighten the sensor because there is a risk of damaging its thread. once this finishes, next steps onwards are easy.
tips. best position is to stand next to the pollen filter box and confront the driver side mirror. use the right hand to get access to the sensor. it is an advantage to have small hand & fingers. lol.
i did the removal before maghrib then stop then continue after pray. installation of new sensor was in dark without proper light but it makes no difference since it requires good hand sense only.
after all done. i took the car for a spin and so far that CEL never comes back. otherwise i will have to look for other culprits.
