Code P0461 2015 Chevrolet Silverado Description
The primary fuel level sensor and the secondary fuel level sensor change resistance based on fuel level. The Fuel Pump Driver Control Module monitors the signal circuits of the primary fuel level sensor and the secondary fuel level sensor and sends the signal information to the Engine Control Module (ECM) for all further handling. The ECM uses this value in order to determine the fuel level. When the fuel tank is full, the resistances of both fuel level sensors are low, and the ECM senses a low signal voltage on both the signal circuits of the primary fuel level sensor and the secondary fuel level sensor. When the fuel tank is empty, the resistances of the fuel level sensors are high, and the ECM senses a high signal voltage. The ECM uses the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to calculate the percentage of remaining fuel in the tank. The ECM sends the fuel level percentage via the serial data circuit to the instrument cluster in order to control the fuel gauge.

The primary fuel level sensor and the secondary fuel level sensor change resistance based on fuel level. The Engine Control Module (ECM) monitors the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to determine the fuel level. When the fuel tank is full, the resistances of both fuel level sensors are low, and the ECM senses a low signal voltage on both the signal circuits of the primary fuel level sensor and the secondary fuel level sensor. When the fuel tank is empty, the resistances of the fuel level sensors are high, and the ECM senses a high signal voltage. The ECM uses the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to calculate the percentage of remaining fuel in the tank. The ECM sends the fuel level percentage via the serial data circuit to the instrument cluster in order to control the fuel gauge.
The Diagnostic Trouble Code (DTC) will be set if the ECM detects a change in fuel level of less than a specified amount (typically 3 - 10 L or 0.8 - 2.6 gal) over a specified driving distance (typically 240 - 320 km or 150 - 200 miles).
What are the Possible Causes of the DTC P0461 2015 Chevrolet Silverado?
- Faulty Fuel Level Sensor
- Fuel Level Sensor harness is open or shorted
- Fuel Level Sensor circuit poor electrical connection
- Faulty Instrument Cluster
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0461 2015 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0461 2015 Chevrolet Silverado Code
1. What does the OBDII code P0461 mean on a 2015 Chevrolet Silverado?
P0461 indicates a "Fuel Level Sensor Performance" issue, meaning the fuel level sensor is not providing accurate or consistent readings to the vehicle's computer.
2. What are the symptoms of code P0461 in a 2015 Chevrolet Silverado?
Common symptoms include erratic or inaccurate fuel gauge readings, an illuminated check engine light, poor fuel efficiency monitoring, or difficulty diagnosing low fuel levels.
3. What causes the P0461 code on a 2015 Chevrolet Silverado?
Possible causes include a faulty fuel level sensor, wiring issues like damaged or corroded connections, a malfunctioning instrument cluster, or a problem with the fuel pump module.
4. Can I drive my 2015 Chevrolet Silverado with a P0461 code?
Yes, you can typically drive the truck with a P0461 code, but it’s not recommended for long periods as inaccurate fuel readings can lead to running out of fuel unexpectedly.
5. How do I fix the P0461 code on my 2015 Chevrolet Silverado?
Repairs may include replacing the fuel level sensor, inspecting and repairing wiring or connectors, and, in some cases, reprogramming or replacing the instrument cluster.
6. How much does it cost to fix a P0461 code on a 2015 Chevrolet Silverado?
Repair costs can range from $150 to $500, depending on whether the fuel level sensor, wiring, or other components need replacement.
7. Where is the fuel level sensor located in a 2015 Chevrolet Silverado?
The fuel level sensor is located inside the fuel tank, usually as part of the fuel pump assembly.
8. Can a bad fuel level sensor cause other issues besides the P0461 code?
Yes, a faulty sensor can lead to inaccurate fuel readings, difficulty determining when to refuel, and potential stalling if the tank is mistakenly thought to have fuel.
9. Will clearing the P0461 code fix the problem on a 2015 Chevrolet Silverado?
Clearing the code will turn off the check engine light temporarily, but if the underlying issue is not resolved, the code will reappear.
10. How do I diagnose the P0461 code on a 2015 Chevrolet Silverado?
Diagnosis involves checking the fuel level sensor for proper operation, inspecting the wiring and connectors for damage, and testing the fuel pump module and instrument cluster for faults.
