+1 ...that's the MAF sensor (Mass Air Flow sensor/meter). If you need 02 sensors, you are looking for these.

These are usually cheaper because they don't have the harness (plug)... You would have to use your original harness from the 02 sensor you're replacing.

I got a P0150 - O2 Sensor Circuit Malfunction (Bank 2 Sensor 1) from my reader.
It goes away after a few days/drive cycles.
Which is which?

there's the 4 sensors for a 99, just don't know which is which still.
bank 1 is probably the front sensors.
someone here must know for sure.

I'm not sure which is which but I had P0156 and p0161 codes.
Bought a can of MAF cleaner at PepBoys. Car runs stronger than
it did before after using the cleaner, even used it on the ML320
and the idle shakes are now gone.

P0161 - O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
Whats the differences between these two codes... Trying to get this resolved and after further investigation I noticed the detail of the two codes was different.

autohausaz.com is where I picked mine up from. You need the two 02 sensors before the cat and the 2 after the cat. That should clear up your problems. Easy fix if you could easily get under ur car and you just follow what you take out and reinstall the new ones just like the old ones.

I cannot imagine that all 4 O2 sensors went bad at the same time. Or, for that matter, that both primary CATs failed at the same time. For this, I would go with cleaning and or replacing MAF. My 2 cents.
