SOURCE: 2002 honda crv fuel gauge moves really slow.

I had the same problem. My battery was going bad. When I replaced it with a new one, the fuel gauge worked fine.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

SOURCE: Full tank of gas and getting low fuel indicator on dash

Bad fuel level sensor. Unfortunately it is located inside the gas tank. Fairly common problem on GM's. Due to sulphur in fuel. Corrodes the sensor tabs. Expensive to have repalced and NOT a do-it-yourself project, unless you have dropped a tank before.

SOURCE: Volvo S80 gauge indicates no or low fuel even when

The most likely culprit is a faulty Fuel Level Sending Unit (sends fuel level from tank to dash gauge). It may be stuck, or beyond repair and in need of replacement. Dealing with electronics in your tank can be tricky and should be dealt with by a professional.

Good luck!

2006 Chevy Colorado Truck. Gas tank filled and fuel gauge indicator dropped to 1/4 full, when truck is idling fuel gauge drops to empty and low fuel light comes on. Suggestions? Thank you.


Check and or test fuel gauge sending unit and the gauge . Videos on youtube showing how to . Also i would have the vehicle checked for DTC's - diagnostic trouble codes . You may want to think about taking to a qualified repair shop .

Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the BCM indicating the fuel level percent. The fuel gage defaults to empty if:
• The ECM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of serial data communications with the BCM.
• The BCM detects a loss of serial data communications with the ECM.

DTC P0461
The fuel level sender changes resistance based on fuel level. The powertrain control module (PCM) monitors the signal circuit of the fuel level sender in order to determine fuel level. When the fuel tank is full, the sender resistance is low and the PCM senses a low signal voltage. When the fuel tank is empty, the sender resistance is high and the PCM senses a high signal voltage. The PCM uses the signal circuit of the fuel level sender in order to calculate the total remaining fuel percent in the tank. The PCM sends the fuel level percent via the class 2 serial data circuit to the instrument cluster in order to control the fuel gage. The fuel level information is also used for misfire and evaporative emission (EVAP) diagnostics.

DTC P0463 Fuel Level Sensor Circuit High Voltage

Town and Country Van running out of gas and guage says half a tank what could be the problem?


If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it
