Bank 1 is driver's side. O2 sensor 1 is before cat converter, O2 sensor 2 is after converter. #1 should be in the downpipe from the exhaust manifold.

Where is the oxygen sensor located on a 1999 GMC Yukon with a 350.


You have four O2 sensors in your vehicle. Bank 1 and Bank 2. Typically it is Bank One, sensor Two that goes out from minor oil leaks on your engine. Here are a couple diagrams. Lay down behind your right front tire and look up. Look for cracked wires or burnt areas by connection. You can't always tell by looking. Easy to replace and fairly cheap.

How many o2 sensor are on a 2004 gmc yukon


Hi Charles,

GM products have 4 O2 sensors attached along the exhaust pipes coming off the manifold. Bank 1 is aligned to cylinder 1 on the engine which is the driver's side. Sensor 2 is the one after the convertor (Sensor 1 being the one before the convertor). Link attached for more information.

Oxygen Sensor Locations

I have changed out one of mine; quite easy, but you need a sensor wrench which you can find an any automotive store for around $15.

The part is available readily enough - link attached.

Good luck

you may have two oxugen sensors on your yukon. if so the oxygen sensor that controls that bank may be bad. from what you mentioned in your complaint, it sounds like it is the oxygen sensor.
