Hey there, Lawrence!
Alright, sounds like your 2006 Silverado is throwing a code for the O2 sensor heater circuit. Don't worry, these aren't super uncommon. Since the scan tool isn't pinpointing the exact issue (positive or negative side), let's explore some common culprits:
1.) Fuse Felon: First things first, check the fuse box under the hood. Your Silverado should have specific fuses for the O2 sensor heaters, likely labeled something like "O2 Sensor" or "Heater." Check your owner's manual to pinpoint the exact fuse locations. If a fuse is blown, replace it with the correct amperage fuse (don't upsize!).
2.) Wiring Blues: If the fuse looks good, the problem might be with the wiring itself. These can get brittle and crack over time. Look for any damaged wires around the O2 sensor (typically located in the exhaust manifold) and follow the wiring harness towards the fuse box. Inspect the wires for any breaks or exposed sections.
3.) Bad O2 Sensor (but less likely): Less likely, but possible, is the O2 sensor itself failing. While the heater circuit is separate from the sensor's main function, sometimes a faulty sensor can also cause weird heater circuit readings.
Here's a tip: before you start digging into the wiring, refer to a repair manual for your specific Silverado year and engine size. It'll show you the exact location of the O2 sensors and the wiring harness route.
If you're not comfortable troubleshooting the wiring yourself, a mechanic can pinpoint the problem and get your Silverado breathing easy again.
