P0461 Fuel Level Sensor Circuit Range Performance

Definition: P0461 is an OBD-II generic code that indicates a fault with the fuel level sensor circuit, where the signal sent to the engine control module (ECM) is not within the expected range.

Description: The fuel level sensor sends a voltage signal to the ECM that corresponds to the amount of fuel in the tank. If this signal does not match what is expected based on other data inputs, such as vehicle speed and distance traveled, it triggers a P0461 code.

P0461 – Fuel Level Sensor Circuit Range/Performance

Severity: Moderate

Common Causes

p0461 – Fuel Level Sensor Circuit Range/Performance

• Issues with the fuel gauge itself
• Problems with the powertrain control module (PCM)

 

Common Misdiagnosis

OBD2 Code: P0461

Description: Fuel Level Sensor Circuit Range/Performance

Common Misdiagnosis: Replacing the fuel level sensor without checking for wiring issues or a faulty instrument cluster.

 

Common Diagnostic Steps

OBD2 Code: P0461

Description: Fuel Level Sensor Circuit Range/Performance

• Check the fuel level sensor and wiring for damage or disconnection.
• Inspect the fuel tank for any signs of deformation or damage that could affect sensor readings.
• Test the voltage and ground at the fuel level sensor connector using a multimeter.
• Verify the integrity of the fuel level sensor circuit by checking for continuity and resistance in the wiring harness.
• Use a scan tool to monitor live data from the fuel level sensor to ensure it is providing accurate readings.
• If applicable, check for any technical service bulletins (TSBs) related to this code for specific vehicle models.
• If necessary, replace the faulty fuel level sensor with a new one and clear any stored codes before retesting.
