My check engine light came on yesterday upon starting my car after it sat all night in the garage.  Had it checked for a repair code today and it showed code is P1167  MOD  No DTC Definition Found.  See Service Manual.  
Had the code looked up and was told it is the Lean Air Fuel Sensor (Bank 1 Sensor 1) Heater Circuit Malfunction - Manual and Automatic Transmission this was pulled off of a computer at Speedy Got this off of my own computer reading.  P1167 Honda Description The Air/Fuel Ratio (A/F) sensor 1 is installed in the exhaust system and detects oxygen content in the exhaust gas. The A/F sensor transmits output voltage to the Engine Control Module (ECM). A heater for the sensor element is embedded in the A/F sensor (sensor 1). It is activated and heats the sensor to stabilize and speed the detection of oxygen content by controlling current flowing through the heater. An increase in the current levels off as the applied voltage to the element electrode reaches a certain range because the amount of oxygen which is led through the diffusion layer is limited. The current amperage is proportional to oxygen content in the exhaust gas, so the air/fuel ratio is detected by the measurement of the current amperage. The ECM compares a set target air/fuel ratio with the detected air/fuel ratio and controls the fuel injection timing. If the A/F sensor (sensor 1) voltage is low, the air/fuel ratio is lean, and the ECM uses A/F feedback control to issue a Rich command. If the A/F sensor (sensor 1) voltage is high, the air/fuel ratio is rich, and the ECM uses A/F feedback control to issue a Lean command.
