Fuse for O2 sensor heaters
Hello my friend with catless race headers (no problems for 10,000 miles) threw a code saying insufficient heating to both the front and rear O2 sensors on both sides. He looked through the manual but couldn't find the fuse for the O2 sensor heater. Which fuse is it and what amps?

Before youi try something drastic or expensive, perhaps try removing, inspecting and cleaning any buildup on them. It could cause poor heating performance that is critical for stabilizing measurements

The fuse was blown, replaced, CEL went away. Back to hooning - says my friend
