The fuel gauge inclination sensor may need to be adjusted if the combination meter has been replaced or the fuel level reading is found to be erroneous due to the distinctive bladder design of the 20012003 Prius fuel tank.
Procedure for reset (See Figures 1 and 2):
- The car should be parked on a flat surface.
- Switch the ignition on to the “on course.
- Incorporate the odometer display into “Mode ODO.
- Switch off the ignition.
- While adjusting the ignition switch to the “On position, depress and hold the “ODO/TRIP button. ODO button held down for two seconds.
- Within five seconds, hit the ODO button three more times while holding it down between presses: Release-Press-Release-Press-Release-Press. Hold the ODO button down for at least five seconds until the odometer displays the leveling data.
- Turn the button off.
- Hold down the “ODO/TRIP button while waiting for the odometer display to indicate that the reset has started (odometer reads “1).
- The odometer goes back to normal after the reset is finished.
- OFFSET the ignition.
A few tries may be necessary to complete this process. This process must be restarted from the beginning if you are interrupted or make an error at any point during it. Remove the key from the ignition each time you restart, then wait for at least five seconds.

How is a gasoline gauge reset?
It is most likely a software or electronic fault that affects your car’s fuel gauge if you detect an erroneous measurement or display of the amount of fuel in your gas tank.
A reset is the main fix for an unreliable fuel gauge. In most cases, the manufacturer of a car specifies how to reset the fuel gauge in the handbook or manual. The steps are the same for the majority of automobiles, though. Resetting the Mercedes fuel gauge is not an exception.
- Press and maintain the “Do/Trip button Activate the ignition and hold the “For around two seconds, switch between Trip and Odo. then let go of the “Press and hold the Trip/Odometer button for four to five seconds to see the leveling information appear on the Odometer. Repeat this process three or four times. then let go of “Do/Trip button
- Lastly, remove the button after the Odometer display returns to normal “Because the reset has just been finished, press the Trip/Odo button.
- To place the Odometer in “ODO mode, press the “Trip/Odo” button.
- Once more, wait until the odometer reads “1” before pressing and holding the “Trip/Odo button. This signals that the reset procedure has started.
- Offset the ignition of the car.
- the ignition switch on the car to the “position of ON.
Why isn’t my fuel gauge showing the correct amount?
A faulty fuel sending unit is the most frequent issue that results in the fuel gauge reading inaccurately. The gasoline sending device measures the fuel level in the fuel tank and transmits that information to the fuel gauge on the dashboard of the car. It also alerts the driver when the car is running low on fuel and when to stop at a gas station before the tank is empty, ensuring that the driver is always aware of the fuel level. Let’s examine how the two components interact to see how the fuel gauge is the first to indicate a problem with the fuel sending unit.
Why does my fuel gauge remain at 100%?
The absence of a ground at the sender, an open circuit, or a break in the wire connecting the gauge and the sender are often to blame for this sort of gauge reading over full.
Why does my fuel light come on even when my tank is full?
Your low fuel warning light ought to go out once you fill up at the closest gas station.
Your fuel level sensor may need to be serviced if your light remains on even when your gasoline tank is full. Consider utilizing higher grade fuel. Lower grades may contain traces of water or have additional contaminants, which could harm your sensor.
Taking your automobile to a repair might be a smart idea if you are still experiencing issues. Your mechanic will examine your sensor for flaws and clean or replace the sensor as necessary. Your fuel tank may also be inspected for flaws by your mechanic.
Depending on the make and model of your car, replacing your fuel sensor could run you $200 to $300.
How can my fuel gauge be tested?
Does your fuel gauge read correctly? Is it completely broken now? Older boats frequently have this issue, but it is simple to correct. Identifying if the gauge or sending unit is at fault is the first step. It is simple to pass the test for this. Make that the gauge is receiving 12 volts of power first. The positive terminal on the back of the gauge, which should be marked with a “+ or a “I, should be probed with a multimeter while the engine is running. If there is no voltage, the ignition circuit is presumably at fault and the gauge is probably in good shape. If the gauge reads 12 volts, the issue is most likely with the sender, the gauge, or its wiring, so move on to the next step.
Disconnect the sending wire when the gauge is powered up; it will be identified by a “S at the back of the gauge. As soon as the wire is severed, the gauge ought to read as high as it can. If so, the gauge is good, and you can move on to the subsequent stage. The gauge is defective and needs to be changed if the maximum reading is not reached.
Another test is to cross the sending pin and the ground pin on the back of the gauge using a wire or a screwdriver. Use a longer wire to jump the transmitting pin to the engine block if there isn’t a ground pin. The gauge should reach its lowest reading once you do this. If so, it is in good operating order.
The remaining system parts must be in working order if the gauge is accurate; otherwise, there must be a problem with either the wire leading to the sender or the sender itself. Disconnect the wire between the sender and the “S pin on the back of the gauge to inspect it. Check the resistance in the wire with your multimeter set to the Ohms scale. The circuit is in good condition and the sender is defective if there is no resistance (or as near to 0 Ohms as feasible). Replace both the sender and the gauge to be absolutely certain you are getting accurate readings because typically the sender and the fuel gauge need to be matched to the resistance in the sender’s rheostat. Numerous businesses offer pre-assembled “ready-to-go installation kits.
Why does my fuel gauge fluctuate?
The fuel level sender in the gasoline tank is most frequently to blame for fluctuating fuel levels when it is broken, misaligned, or unable to rise all the way to its full position. In order to avoid having to pay for further labor in the future to replace the pump or filter, I would advise replacing the fuel sender in the fuel tank along with the gasoline pump and filter.
Why doesn’t my automobile register fuel?
A defective fuel level transmitting unit is the most frequent cause of a fuel gauge not functioning properly or being inaccurate. Inadequate wiring between the gauge and gasoline sender or a blown fuse for the fuel gauge are other potential causes. It’s also possible for the fuel gauge to become damaged.
The most frequent reasons why your fuel gauge is not working or is inaccurate are listed in greater detail below:
Defective Sending Unit
The sending unit is where the process starts in its entirety. The sending unit continuously checks the fuel level in the tank when your car is moving. However, due to its frequent use, it is vulnerable to wear.
The circuits can continue to function if the contacts become worn. Depending on how the car is configured, the fuel gauge may interpret the voltage feedback as indicating that the tank is either empty or full. In this situation, regardless of the amount of fuel in the tank, the gas gauge won’t move.
The fuel gauge sensor is where?
The fuel gauge sender is located inside your car’s fuel tank. Direct connection will be made to the fuel pump.
The sender has a base with a float and rod attached to it, making it easy to find. This float is hollow in construction and is not heavy. It doesn’t sink because it’s designed to rest on the fuel surface. A rheostat meter on the rod that connects directly to the base measures the amount of fuel in your car’s tank.
How much does repairing a fuel gauge cost?
A malfunctioning gas gauge is undoubtedly annoying, but it is unquestionably a fixable problem! Depending on the model of the automobile, you might get the part for between $50 and $200 to fix the gas gauge for the least amount of money.
If you decide to visit a repair facility, budget $200 to $300 for labor if you purchase the new gauge on your own. According to some reports, you’ll pay between $300 and $1,000 at a dealership, depending on the type and model of your car.
You should always check your insurance to see if your extended warranty covers this.
However, there are other ways to cut costs on the repair if your warranty does not cover it. Try downloading the Jerry appwell to see if you can save money on your auto insurance.
