Hi All,

The engine light is on on my 99 RX. The code is P0170. I have cleaned the MAF sensor, resetted it but it comes on again. I have just ordered a Air Fuel Ratio Sensor from ebay, part# 89467-48011. Can someone please tell me where is this sensor located? Is it easy to replace? Thanks a lot.

 

There are 3 air fuel sensors.

If you do a search on here it will tell you.

 

I did do a search and I knew that there are 3 O2 sensors. But still don't know where are they located? Are they the same or 3 different parts? Thanks so much!!!!!
