Details of the Toyota p1150 OBD Code
Toyota fault code P1150 relates to an issue with the Air/Fuel Ratio Sensor Circuit Range/Performance.
Code P1150 on a Toyota indicates an issue with the Air/Fuel Ratio Sensor Circuit Range/Performance.
This code is triggered by the Engine Control Module (ECM) when it detects that the signal from the Air/Fuel Ratio Sensor (often referred to as the upstream oxygen sensor) is not within the expected range or is performing outside of its normal parameters.
The Air/Fuel Ratio Sensor is a critical component in monitoring and adjusting the airtofuel ratio for optimal combustion efficiency in the engine.
When the ECM detects a fault with this sensor or its circuit, it will trigger the P1150 fault code.
Mechanic’s Tech Notes
