Or More After Starting Engine Engine Coolant Temperature Is More Than 40 °C (104°F) (1 Trip Detection Logic)	Open Or Short In Heated Oxygen Sensor (Bank 1 Sensor 1) Circuit Heated Oxygen Sensor (Bank 1 Sensor 1) Heated Oxygen Sensor Heater (Bank 1 Sensor 1) EFI Relay Air Induction System Fuel Pressure PCV Hose Connection PCV Valve And Hose Injector Gas Leakage In Exhaust System ECM

NOTE: After confirming DTCs "P0134", use the hand-held tester or the OBD II scan tool to confirm the output voltage of the heated oxygen sensor (bank 1 sensor 1) from the "DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL". If the output voltage of the heated oxygen sensor is always less than 0.1 V, the heated oxygen sensor circuit may be open or short.
