P2065 OBD-II Trouble Code: Fuel Level Sensor B Circuit

P2065 code definition

A P2065 trouble code refers to a detected problem with the fuel level sensor "B" circuit

What the P2065 code means

A P2065 indicates that the Powertrain Control Module (PCM) has detected an irregular voltage signal from one of the fuel level sensors. Fuel sensors are used to gauge the amount of fuel currently in the gas tank. The "B" circuit indicates a specific area in the fuel level sensor circuit. This area should be denoted visibly on the hardware.

What causes the P2065 code?

  • In the majority of cases, a faulty instrument cluster is to blame

  • A damaged fuel tank

  • Loose grounding wire, and shorted or broken circuitry.

  • In very rare cases, a PCM or other control module may be faulty and mistakenly registering the code.

However, due to the rarity and high expense involved in module replacement, it should only be considered a last-ditch resort after all over possibilities have been exhausted.

What are the symptoms of the P2065 code?

If a P2065 code applies to a vehicle, the fuel gauge will be inaccurate and erratic. In some cases, the fuel gauge may read a fuel level below zero. In cases where a vehicle is equipped with a "low fuel" warning, this warning bleeper may signal itself erratically, regardless of the actual level of fuel inside the tank.

In addition, the trouble code and illuminated dashboard trouble lamp will be activated. These symptoms are purely diagnostic in nature, and used only in order to indicate that there is a problem in the first place.

How does a mechanic diagnose the P2065 code?

A P2065 code may be first identified by scanning it with an OBD-II code reader. Primary components in the fuel level system (such as the instrument cluster and fuel tank) should be inspected for signs of fault or damage. Running a smoke machine through the fuel system will give a visual indicator where any cracks (if any) are along the body. Any wiring and connectors related to the fuel level system should be checked out for sign of corrosion, fault, wear and disconnection. If all other possible causes have been ruled out, the PCM may be considered as a possible issue.

Common mistakes when diagnosing the P2065 code

The electrical circuitry relating to the fuel delivery system should be thoroughly inspected, especially first before investing in expensive replacement components. Electrical problems are sometimes overlooked and components unnecessarily replaced instead.

How serious is the P2065 code?

Although it may not have a practical effect on the vehicle's drivability, not knowing how much fuel there really is in the gas tank can be a big concern, particularly on longer trips. In addition, certain causes (like a damaged fuel tank) that account for a P2065 may have further-reaching consequences.

What repairs can fix the P2065 code?

. It is important to keep in mind that this last-ditch option is very costly compared to smaller repairs. Therefore, it should only be considered once it has been identified as the problem with relative certainty.

  • Finally, after making all repairs, the vehicle should be test started to see if the issue returns. This post-test will help verify that the problem has been solved for good.

Additional comments for consideration regarding the P2065 code

In the case of fuel tank damage, the P2065 code will be likely reported alongside other trouble codes relating to the fuel delivery system.
