P2065 to P2069: fuel level sensor B
The second fuel level sensor (B) has a circuit fault or an implausible, low, high or intermittent signal.
SeverityLowLittle risk to the car, but the fault stays until it is repaired.

Cars with all-wheel drive or rear-wheel drive often have a saddle-shaped tank that sits over the driveshaft, with two halves, each with its own level sensor. The fuel gauge adds the two readings. Where P0460 to P0464 cover sensor A, these codes cover sensor B. If it fails, the fuel gauge and the range shown can be wrong by up to half a tank, which matters most when the tank is getting low.
What causes P2065?
- A worn resistor track in the second sender
- A float stuck or soaked with fuel in the second half of the tank
- A corroded connector on the tank's second access cover
- A damaged wire between the tank and the instrument cluster
What to check first for P2065
- At the next fill-up, compare how much fuel goes in with what the gauge showed
- Note whether the gauge jumps or stays fixed over part of the tank
- Inspect the connector on the second sender, often under the rear seat on the other side
- Have the second sender's resistance measured from full to empty
Can you drive with P2065?
You can drive safely. Do not rely on the fuel gauge or the range until it is repaired: refuel by the trip meter and keep the tank above a quarter.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.

These are the generic meanings every manufacturer shares. Each brand adds its own detail, so your car's handbook, its service information and a qualified mechanic have the last word. OdoKeep has no connection with any manufacturer, and the app does not read codes from the car.
