P0461 on 2017-2019 Nissan Versa Note: Fuel Level Sensor Causes and Fixes

What's Unique About the 2017-2019 Nissan VERSA NOTE

For the 2017-2019 Versa Note, this is a known issue acknowledged by Nissan. The manufacturer issued a Technical Service Bulletin (NTB22-026) that specifically lists P0461 and points to the fuel level sensor as the cause. Crucially, the bulletin clarifies that the sensor can be replaced on its own, which can save owners money compared to replacing the entire fuel pump module. The TSB even warns dealerships that warranty claims for replacing the entire pump assembly for this code will be charged back, strongly indicating the sensor is the sole intended repair.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Erratic or fluctuating fuel gauge
• Fuel gauge stuck on full or empty
• Check Engine Light is on
• Low fuel warning light may stay on or flash, even with a full tank
• Distance to Empty (DTE) reading is inaccurate or does not update after refueling

Most Likely Causes

1. Faulty Fuel Level Sensor (Sending Unit) 🔴 High Probability This is a known issue confirmed by Nissan TSB NTB22-026. The sensor's internal resistor strip or the wiper that moves across it can wear out over time from the constant movement of the float arm, creating dead spots or open circuits.
   How to confirm: Access the fuel pump assembly and test the sensor's resistance with a multimeter while moving the float arm. The resistance should change smoothly. For many Nissan vehicles, the expected range is approximately 4-6 ohms at full and 78-82 ohms at empty, though specific values for the Versa should be confirmed. Jumps, infinite readings (OL), or readings that don't change indicate a bad sensor.
   Typical fix: Replace the fuel level sensor. It is located on the fuel pump module inside the gas tank but can be purchased and replaced separately. 🎬 Watch: Step-by-step fuel sensor replacement on a 2017 Versa Note
   Est. part cost: $80-$150
2. Damaged Wiring or Corroded Connector 🟡 Medium Probability The wiring and connector on top of the fuel tank are under the rear seat but can still be susceptible to damage during other repairs or if moisture intrudes, leading to corrosion or loose pins.
   How to confirm: Visually inspect the wiring harness and connector at the top of the fuel pump assembly for any signs of corrosion, frayed wires, or loose pins. Test for 5V reference and good ground at the connector using a multimeter.
   Typical fix: Clean the connector terminals with an electrical contact cleaner or repair/replace the damaged section of the wiring harness.
   Est. part cost: $5-$50
3. Stuck or Damaged Float Arm ⚪ Low Probability While less common, debris in the fuel tank or physical damage from incorrect installation of the fuel pump assembly can cause the float arm to get stuck, preventing it from accurately reading the fuel level.
   How to confirm: After removing the fuel pump assembly, visually inspect the float and arm for freedom of movement and any signs of damage or obstruction.
   Typical fix: Free the stuck float. If the float or arm is damaged, the fuel level sensor assembly must be replaced.
   Est. part cost: $80-$150

Rare But Worth Checking

• Faulty Instrument Cluster: While rare, the gauge cluster itself can fail, causing it to misinterpret a correct signal from the sensor. This should only be considered after the sensor and wiring have been confirmed to be good.
• Faulty Powertrain Control Module (PCM): This is extremely rare. The PCM is the last component to suspect. A software glitch could also be a cause, which might be resolved with a firmware update from a dealer.

Diagnosis Steps

1. Read the trouble codes with an OBD-II scanner and confirm P0461 is present. Check for any other related codes like P0460, P0462, or P0463.
2. Check for relevant Technical Service Bulletins (TSBs). For this vehicle, NTB22-026 is highly relevant.
3. Using a scan tool with live data, monitor the fuel level sensor voltage or percentage. Rocking the vehicle should cause the reading to fluctuate slightly; if it doesn't, the float may be stuck.
4. Depressurize the fuel system. A common method is to pull the fuel pump fuse and run the engine until it stalls.
5. Disconnect the negative battery terminal.
6. Gain access to the fuel pump assembly, which is under the rear seat cushion. The cushion typically pulls up and out. Remove the metal access cover.
7. Disconnect the electrical connector and fuel lines. Have rags ready for minor fuel spillage.
8. Inspect the connector and wiring for any signs of corrosion, damage, or loose pins.
9. Remove the large plastic lock ring holding the fuel pump assembly in place. This may require a specialized tool or careful use of a brass punch and hammer to rotate it 🎬 See how to safely remove the fuel pump lock ring counter-clockwise.
10. Carefully lift the fuel pump assembly from the tank, being cautious not to bend the float arm.
11. With the assembly removed, connect a multimeter set to Ohms to the sensor's pins. Manually move the float arm from empty to full. The resistance reading should change smoothly and consistently. Jumps or infinite readings (OL) confirm a bad sensor.
12. If the sensor tests good, the problem likely lies in the wiring between the sensor and the PCM, or, rarely, the instrument cluster.

Platform-Specific Known Issues

• Nissan issued Technical Service Bulletin NTB22-026 for multiple models, including the 2017 Versa Note, which directly addresses codes P0460, P0461, P0462, and P0463, identifying the fuel level sensor as the problem component.
• Owner forums and YouTube videos for the Versa platform frequently discuss this issue, with many DIY-focused owners successfully performing the repair by only replacing the sensor.

Mechanic-Grade Diagnostic Values

• Fuel Level Sensor Voltage at Connector — expected: Approx. 0.5V to 4.5V, changing smoothly as fuel level changes. Note: Sources conflict on whether 0.5V is Full or Empty.. Failure: Voltage is stuck, jumps erratically, or is outside the 0.3V to 4.7V range.
• Fuel Level Sensor Resistance — expected: A smooth, consistent change in resistance as the float arm is moved from empty to full. A common generic range is ~20 Ohms (Full) to ~250 Ohms (Empty).. Failure: Sudden jumps in resistance, or an infinite (OL) reading at any point in the float's travel.

Scan Tool Commands That Help

• Nissan CONSULT: Active Test for Combination Meter / BCM — To command the fuel gauge to specific positions (e.g., 1/4, 1/2, 3/4) to verify if the instrument cluster gauge itself is working correctly, which helps isolate the problem to either the gauge or the sensor/wiring.
• Manual Procedure (No Scan Tool): Instrument Cluster Self-Diagnostic Mode — To initiate a full gauge sweep test. This confirms the physical and electrical integrity of the fuel gauge needle motor. If the gauge sweeps correctly during this test, it is likely functional, pointing towards the sensor or wiring as the culprit.

Wiring & Ground Locations

• Fuel Pump Fuse — In the under-hood fuse box, position F19 (15A).. While this fuse powers the fuel pump motor and not the sensor circuit directly, it must be removed to depressurize the system before servicing the fuel pump assembly where the sensor is located.

OEM Part Supersession History

• 25060-3AN0A → Unknown — Part applicability appears to change for later models.
  Heads up: Multiple parts suppliers indicate that part number 25060-3AN0A is for Versa Note models built up to May or August of 2018. Owners of late 2018 or 2019 models must verify the correct part number for their specific vehicle, as it may differ.

Model Year Variations Within This Range

• 2018-2019: The fuel level sensor part number (25060-3AN0A) is specified for models with a production date up to mid-2018 (e.g., before 05/31/2018). This indicates a potential part change for vehicles manufactured in late 2018 and for the 2019 model year. Verifying the correct part via VIN is critical for these model years.
