— Yes, but your fuel gauge will be unreliable or read empty. This creates a significant risk of unexpectedly running out of fuel.
Key Takeaways
- P0462 on a 2018-2022 Nissan Kicks is most likely caused by a failed fuel level sensor.
- A Nissan TSB (NTB22-026) exists for this exact problem, which is a strong indicator of the root cause.
- You do NOT need to replace the entire expensive fuel pump assembly; the sensor can be purchased and replaced on its own.
- Symptoms are straightforward: an illuminated Check Engine Light and an unreliable fuel gauge.
- Diagnosis involves testing the sensor's resistance with a multimeter to see if it changes smoothly through its range of motion.
The trouble code P0462 stands for "Fuel Level Sensor 'A' Circuit Low". This means the vehicle's main computer, the Powertrain Control Module (PCM), has detected that the voltage signal from the fuel level sensor is below the normal operating range, often under 0.5 volts. The sensor is a variable resistor attached to a float arm in your gas tank; as the fuel level changes, so does the resistance and the voltage signal sent to the PCM. A 'low circuit' reading suggests a short to ground, a wiring problem, or most commonly, a failed sensor, causing an inaccurate or empty reading on your fuel gauge.
What's Unique About the 2018-2022 Nissan KICKS
Nissan is aware of fuel gauge issues on the 2018-2022 Kicks. The manufacturer released Technical Service Bulletin NTB22-026, which covers the P0462 code. 🎬 Watch: Understanding the P0462 code and common sensor fixes. The bulletin specifically advises technicians to replace only the fuel level sensor, not the entire fuel pump assembly, which can save significant money on the repair. It even states that warranty claims for replacing the entire assembly will be charged back to the dealer, highlighting how known this specific failure is. This indicates that a failing sensor is a known issue for this vehicle.

→ Expect $200-$550 in shop labor. Mention Nissan TSB NTB22-026 so they only replace the $75-$300 sensor (OEM 25060-5RL0A), not the entire fuel pump.
Do you have a multimeter 🎬 Watch: How to test a fuel sending unit with a multimeter. to test the sensor's resistance?
→ Test the sensor terminals while moving the float arm. Resistance must change smoothly between 30 Ohms (empty) and 300 Ohms (full). If it reads zero or infinite, replace it.
→ Visually check for a stuck float arm or corroded pins. If clear, the sensor likely failed internally, a known issue covered by Nissan TSB NTB22-026.
→ Replace the faulty fuel level sensor (OEM part 25060-5RL0A, $75-$300). Per TSB NTB22-026, it can be replaced independently of the fuel pump module.
→ Repair the damaged wiring or clean corroded connector pins with dielectric grease. Ensure the signal wire has no short to ground (resistance under 0.1 Ohms).
Symptoms You May Notice
- Check Engine Light is on
- Fuel gauge is inaccurate, erratic, or stuck on empty.
- Low fuel warning light stays on even with fuel in the tank.
- Fuel gauge needle fluctuates wildly.
⚠️ Don't Waste Money on the Wrong Fix
- Replacing the entire fuel pump assembly. Nissan's TSB NTB22-026 specifically warns against this, stating that only the fuel level sensor needs to be replaced for this code. Replacing the whole assembly is unnecessarily expensive.
Most Likely Causes
- Faulty Fuel Level Sensor 🔴 High Probability → Shop Fuel Tank Sending Unit Nissan issued TSB NTB22-026 specifically for this issue, indicating a known problem with the sensor on this platform. The sensor's internal variable resistor can wear out or the contacts on the resistor track can fail, causing it to send a constant low voltage signal.
How to confirm: Access the sensor and test its resistance with a multimeter. Typical values range from approximately 30 Ohms (empty) to 300 Ohms (full), though a service manual should be consulted for exact specs. An open circuit, short circuit, or a reading that doesn't change smoothly when moving the float arm indicates a bad sensor.
Typical fix: Replace the fuel level sensor. Per the TSB, the sensor can be replaced independently of the fuel pump module.
Est. part cost: $75-$300 - Wiring or Connector Issues 🟡 Medium Probability
How to confirm: Visually inspect the wiring harness from the fuel tank to the ECM for any signs of damage, corrosion, or loose connections, especially at the connector on top of the fuel pump assembly under the rear seat. A short to ground in the signal wire will cause a P0462 code. Check for continuity on the signal and ground wires; resistance should be less than 0.1 Ω.
Typical fix: Repair or replace the damaged section of the wiring harness or clean the corroded connector pins and apply dielectric grease.
Est. part cost: $10-$100 - Stuck Float Arm ⚪ Low Probability This can happen on any vehicle, but is more common in cars that have been sitting for extended periods, allowing rust or sediment to build up.
How to confirm: After gaining access to the fuel pump assembly, observe if the float arm moves freely throughout its range of motion. If it is stuck in the lowest position, it will consistently send a low/empty signal.
Typical fix: In some cases, the arm can be freed. More commonly, the entire sending unit is replaced as the mechanism may be compromised.
Est. part cost: $0-$300 - Blown Fuse ⚪ Low Probability
How to confirm: Check the vehicle's fuse box for any blown fuses related to the fuel system or instrument cluster.
Typical fix: Replace the blown fuse. If the fuse blows again, it indicates an underlying short circuit that needs to be diagnosed.
Est. part cost: $1-$5
Rare But Worth Checking
- Instrument Cluster Malfunction: → Shop Instrument Cluster While rare, a fault within the instrument cluster itself can cause issues with how the fuel level is displayed and may trigger a code. Some owners of other Nissan models have reported this being the root cause after replacing the sensor did not fix the issue.
- Powertrain Control Module (ECM) Fault: This is extremely rare, but a fault in the ECM's internal circuits can lead to a misinterpretation of the fuel level sensor signal. This should only be considered after all other possibilities have been exhausted.
Diagnosis Steps
- Read the trouble codes with an OBD-II scanner to confirm P0462 is present.
- Check for any related TSBs, specifically NTB22-026 for this vehicle.
- Inspect the fuses related to the fuel pump and instrument panel.
- Using a scan tool with live data, observe the voltage from the fuel level sensor. A reading near or below 0.5 volts typically confirms the 'low input' condition.
- Gain access to the top of the fuel tank, which is usually under the rear seat cushion. This involves pulling up sharply on the front of the seat bottom to release the clips.
- Disconnect the fuel pump module connector and inspect it for corrosion or damage.
- Using a multimeter set to Ohms, test the resistance of the fuel level sensor terminals while manually moving the float arm up and down. The resistance should change smoothly, roughly between 30 Ohms (empty) and 300 Ohms (full). If it's stuck, shows an open circuit (infinite resistance), or is shorted (zero resistance), the sensor is bad.
- If the sensor tests good, check the signal wire for a short to ground between the fuel tank and the ECM.
