My check engine light came on yesterday morning with a P0141 and P0161 codes. Looked them up on WJJeeps.com.
O2 Sensor Heater Circuit (Bank 1 Sensor 2)
O2 Sensor Heater Circuit (Bank 2 Sensor 2)
Checked underneath and all connections looked intact. Not exactly sure how these are set up and how to tell if its a problem with one sensor or both. Anyone have an idea what might have triggered these?
