The OBDII codes for a 1996 Chevrolet Silverado 2500 are P0046, P0074, and P0075. They are all related to the vehicle’s emission system. This system uses an oxygen sensor to measure the amount of unburned oxygen in the exhaust stream.

A P0046 code is set when the oxygen sensor has a voltage of 0.5 volts or less when the engine is running. A P0074
