2004 ford thunderbird
I have a 2004 ford thunderbird and am trying to locate the two upstream oxygen
sensors. Does anyone have a picture to help me locate them. thanks much
Look on the exhaust pipes near the engine.
The upstream O2 sensors will be the first sensor you find going from the exhaust manifold at the engine along the exhaust pipe towards the rear of the vehicle. The will be on the engine side of the catalytic converters. The O2 sensors past the catalytic converters are the down stream ones.
