P0698: Understanding The Fuel Pump Control Circuit Low Voltage Fault
The P0698 fault code indicates a problem with the sensor reference voltage ‘C’ circuit. The control module in the vehicle has internal 5-volt reference buses that provide a 5-volt reference circuit for multiple sensors.
If there is a fault condition on one 5-volt reference circuit, it can affect the other circuits connected to the reference bus. The control module constantly monitors the voltage on these reference buses.
The P0698 code specifically points to a low voltage condition in the sensor reference voltage ‘C’ circuit. This issue needs to be addressed to ensure proper functioning of the sensors and overall vehicle performance.
FAQ
