97 Chevrolet Silverado with P0141 and P0161 O2 Sensor Fault Codes
My 'Service Engine Soon' light has come on. Using a diagnostic code reader, I've identified trouble codes P0141 and P0160. These codes are typically associated with oxygen (O2) sensor issues. While some users suggest that having both codes simultaneously is unusual, they also note it might not be related to the O2 sensors themselves but could point to a broader system problem. I'm looking for input from others who have experienced similar issues on their 1997 Chevrolet Silverado. Any insights or troubleshooting steps would be greatly appreciated.
It's not uncommon to see both P0141 and P0161 codes on a 1997 Chevy Silverado. Start by checking for any blown or missing fuses labeled 'O2' or 'Oxygen Sensor'. If the fuse is intact, then inspect the wiring harnesses connected to the O2 sensors for damage or corrosion.
