P1172 Fault Code: Understanding The Fuel Trim System Malfunction
The P1172 fault code refers to the Rear AF Sensor Bank 1 Sensor 1 Circuit being out of range high. This fault code is related to the AirFuel Ratio (AF) sensor 1, which is installed in the exhaust system to detect oxygen content in the exhaust gas.
The AF sensor transmits output voltage to the Engine Control Module (ECM) and helps control the fuel injection timing. When the AF sensor (sensor 1) voltage is high, it indicates that the airfuel ratio is rich.
In response, the ECM uses AF feedback control to issue a Lean command.
On the other hand, if the AF sensor (sensor 1) voltage is low, it means that the airfuel ratio is lean.
In this case, the ECM uses AF feedback control to issue a Rich command. The P1172 fault code alerts the driver and the mechanic that the Rear AF Sensor Bank 1 Sensor 1 Circuit is reading a voltage that is out of the expected range. This could be caused by a malfunctioning sensor, a wiring issue, or a problem with the ECM. It is important to address this fault code promptly to ensure proper fuel injection and maintain the correct airfuel ratio for optimal engine performance.
FAQ
