P1172 Meaning

The air/fuel ratio (A/F) sensor 1 is installed in the exhaust system and detects the oxygen content in the exhaust gases. The A/F sensor sends the output voltage to the engine control module (ECM). A heating element for the sensor element is built into the A/F sensor (sensor 1). It is activated and heats the sensor to stabilize and speed up the detection of oxygen content by controlling the current flowing through the heater. An increase in current stabilizes when the voltage applied to the element electrode reaches a certain range because the amount of oxygen that is routed through the diffusion layer is limited. The current amperage is proportional to the oxygen content in the exhaust gases, so the air/fuel ratio is detected by measuring 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.

The fuel pump is located on the left frame rail between the fuel tanks. The Engine Control Module (ECM) provides a positive ignition voltage to the coil side of the fuel pump relay. The ECM activates the fuel pump relay, which powers the fuel pump. Fuel is transferred from the rear fuel tank to the front fuel tank to ensure that all usable fuel volume is available for the engine. This Diagnostic Trouble Code (DTC) is set when the ECM commands the transfer fuel pump to turn on and a predetermined change in the front and rear fuel level sensors does not occur.
