What does code P1167 mean?

Q: What does code P1167 mean?

HO2S11 Heater Circuit VS+ Fault Bank 1 Sensor 1. P1167 on Honda vehicles indicates that the powertrain control module (PCM) has detected an abnormal voltage condition in the heater circuit of the primary heated oxygen sensor (HO2S11), which is Bank 1 Sensor 1. The PCM monitors the heater circuit for expected voltage changes when the heater is commanded on, and this code sets when the circuit voltage does not match the commanded state, typically indicating an open, short, or excessive resistance in the heater element or its wiring.
