Having problems with your 1999 Chevrolet Silverado 1500 ?
I need to know where the oxygen sensor is for a 1999 Chevy pickup. My diagnostic reading is Po171.
The o2 sensor has one on the left side b4 the cat and on the right side has one b4 and one after the cat
The o2 sensor is going to be in the exhaust pipe near the cat.or in the exhaust manifold itself on the right side.
