What is a fuel pressure sensor?
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
What does code P018B mean?
The Fuel Pressure Sensor monitors the fuel pressure in the fuel system. The Fuel Pump Control Module uses this information to adjust the fuel pump’s on time as needed. If the Fuel Pump Control Module does not see a change in pressure from the Fuel Pressure Sensor when the fuel pump is activated, it will set code P018B.
What does code P018C mean?
What Is Code P018C? P018C is an OBD II fault code that stands for “Fuel pressure sensor “B” Circuit Low”. There are a few things that can cause this code like a bad sensor, or high or low fuel pressure. It pops up when the Power Control Module (PCM) receives an erratic signal voltage from the fuel pressure sensor.
Can I drive with a faulty fuel pressure sensor?
Engine stalling might occur as the fuel rail pressure sensor goes from bad to worse. You will be driving and then suddenly, your engine will stall. It may also stall while idling. This will make driving extremely difficult (and dangerous) and it should motivate you to do something about it.
