The fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor. Heres a fantastic video on how to test the fuel level sending unit from howstuffinmycarworks youtube.
Dr Fuel Filter Regulator Pump
Fuel level sensor circuit. This component cant be replaced without replacing the pump module though there are some exceptions. The fuel level sensor sender is located in the fuel tank usually integral to the fuel pump module. There is a float attached to an arm that travels along a resistor which is grounded to the tank frame or has a dedicated ground circuit. P0460 is a diagnostic trouble code dtc for p0460 fuel level sensor circuit malfunction. The fuel level sensor is one of the most common reasons that p0463 appears in your diagnostic codes. The fuel level sensor also known as sender is an essential component of the fuel pump module and located in the fuel tank.
Our certified mobile mechanics can come to your home or office to perform the check engine light diagnostic. Attached to the arm is a float that travels with a resistor grounded to the tank frame or a dedicated ground circuit. An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact through ultrasonic waves is called an ultrasonic fuel level sensor in this post we learn how to build a simple fuel tank level indicator circuit using arduino and ultrasonic sensors. The sensor detects a fuel level in the fuel tank and transmits a signal to the engine control module ecm. Usually they cannot be replaced without replacing the fuel pump module though there are exceptions. The fuel level sensor is mounted in the fuel level sensor unit.
Once we are able to diagnose the problem you will be provided with an upfront quote for the recommended fix and receive 2000 off as a credit towards the. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
