GMC C1500 Replacement Oxygen Sensor Information


A C1500 Oxygen Sensor on a GMC truck is a part that controls emissions along with many other functions. When the C1500 Oxygen Sensor malfunctions the truck will get poor fuel economy and performance will lack drastically. Often the malfunctioning O2 sensor will cause erratic hesitation when the accelerator is pushed. Often the truck will surge at all RPM. The part is located on the underside of the vehicle. The GMC Oxygen Sensor on GMC models is threaded into the exhaust system. The part looks like a large black cork with a wire coming out of the top.

The part constantly monitors the performance of the engine in regards to the fuel being rich or lean. When the C1500 Oxygen Sensor reads high levels of emissions a signal is directed to the ECM and the fuels system is directed to burn cleaner. The same is true when the GMC Oxygen Sensor detects the fuel system is burning to lean.
