Pics of smog sensor cleaning.
I while back i asked is there a way to do maintainence on the smog sensor because i noticed mine was reacting a bit sluggish when it came to switching from in outside air to inside air. One member gave helpful info on the location of this sensor so i investigated and did so maitainence of my own. Its surely not on the scale of replacing the timing belt or even brakes but its something i wanted to share anyway.
Pic 1pen hood to located sensor next to the pass. side horn in front of radiator and remove the 10mm bolt.
Pic 2: using a pry tool, pry open the sensor by way of three locking tabs on sides.
Pic 3:inspect layout and condition of the sensor in order to reassemble( its not rocket science).
Pic 4:Seperate filter from holder/pcb cover.
Pic 5:Clean filter or replace with new one of some type(not sure if available separately).
Pic 6: Separate filter holder/pcb cover in order to clean it and the remaining areas on the housing if prefered.
Pic 7: Reverse the instructions to reassemble.
This solved my sluggish isssue with the auto smog function. Works as advertised now.

Very nice work. Thanks for taking the pics and sharing this info with the forum.

I think he means that it was not detecting outside air as fast as one would expect in order to be a worthwhile feature. Like if he was behind a bus and it was spewing exaust fumes at the front of his car, it probably took a considerable amount of time before the air circ. would switch to inside only. I will check mine out to this spring. Great write up!

Excellent write up. All this time I thought the sensor would have been in the air intake housing, but it being that small sensor, I can definitely see that thing jamming up and causing slow reading.
I'll have to make note of this when my sensor starts going cooky.
Thanks a lot for this.
