GMC K1500 Replacement Oxygen Sensor Information

When having problems with the oxygen sensor(s) on your GMC K1500, you may be confronted with multiple diagnostic trouble codes, including PO131 & 137 or PO151 & 157. The specific code should help you determine the exact O2 sensor at fault. Earlier model

GMC K1500s only had one O2 sensor, screwed into the exhaust manifold. Later models have either three or four sensors, depending on whether the rig has one or two catalytic converters installed.

The O2 sensors that are in front, or "upstream," feed information to the engine control unit to help in delivering the proper mixture of air/fuel to the cylinders. The back, or "downstream" sensor(s) supply information regarding the efficient working of the catalytic converter. Any bad sensor(s) should be replaced with a quality part such as those offered at, with more than 100 models from which to choose, covering GMC K1500 for years 1980-1999.

1998 GMC K1500 Oxygen Sensor

Very Satisfied
Reviewer: BuickGS

O2 sensor was exactly as advertised - OEM fit. It was exactly the same as what I was replacing, right down to the wire length and the end connector. I needed two of these and they were in stock, processed and shipped quickly, and saved me quite a bit of money vs buying them at my local parts store.
