Re: 1997 K1500 Silverado O2 Sensor Problems
The P0141 is for H02s bank 1 sensor 2. Bank 1 is the drivers side exhaust system and sensor 2 is the one after the cat. However some light duty 5.7 truck exhaust pipes cross just aft of the engine putting the bank 1 cat on the pass side. So, are you sure the correct sensor is getting replaced?
There are 3 wires. The pink one is 12 volts in the run position to heat the sensor and is powered by "ENG 1" 20a fuse #21 in the underhood fuse box. the other two wires are reference signals to the VCM.
Keep in mind that this info is out of my '98 C/K manual. Your '97 may be different. Hope this helps.........Steve
