LPG Tank Level Sender for Right Multivalve
This round resistive LPG tank level sender is intended for compatible right-hand multivalves in automotive LPG systems. It communicates fuel-level information through a resistance signal interpreted by a compatible gas ECU or changeover switch. DC 5V and DC 12V options are listed, and resistance is customizable.

Why Is My LPG Fuel Gauge Reading Wrong?
A wrong LPG fuel-level reading does not automatically mean the tank is empty or the sensor has failed. A mismatch between sensor resistance and ECU configuration can produce incorrect readings even when the sensor is electrically functional.
Loose connectors, damaged wiring, a faulty level mechanism or an incorrect display configuration can cause similar symptoms.
Common LPG Level Indicator Problems
Problem 1: LPG Gauge Stuck on Empty
If the display stays on empty, check whether the ECU is receiving a valid sensor signal. An open circuit, poor connection, incompatible resistance range or faulty sender may be involved.
Problem 2: LPG Gauge Always Shows Full
A permanently full reading may be caused by incorrect resistance interpretation, a wiring fault or a problem with the multivalve level indication mechanism.
Problem 3: Fuel Level Jumps Around
Some movement can be related to changing liquid level during driving. But repeated sudden jumps or impossible readings deserve an electrical inspection.
Check connector contact, resistance stability and the condition of the multivalve level mechanism.
Problem 4: New Sensor, Same Wrong Reading
Replacing the sender won't fix a mismatched ECU configuration. Compare the new sensor's resistance curve with the input specification of the ECU or changeover switch.
How to Choose the Correct LPG Level Sensor
The important details are sensor orientation, mounting dimensions, voltage and resistance characteristics. A circular housing alone does not establish compatibility.
Check the Multivalve Orientation
This version is intended for compatible right-hand multivalves. Verify the original mounting arrangement before selecting a replacement.
Match the Resistance Curve
LPG fuel-level systems can use different resistance characteristics. The empty and full resistance values and their direction must match the receiving electronics.
Confirm the Electrical Version
DC 5V and DC 12V are listed options. The selected version must match the actual electrical requirements of the installed system.
Resistive LPG Sensor vs Pressure Gauge
| Feature | Level Sensor | Pressure Gauge |
|---|---|---|
| Measures | Fuel level indication | Gas pressure |
| Typical Output | Resistance-related signal | Pressure indication |
| Purpose | Estimate remaining LPG | Monitor pressure |
| Interchangeable | No | No |
Before Replacing the Sensor
Confirm the original sensor and multivalve configuration.
Identify the required voltage and resistance characteristic.
Check accessible electrical connections for damage.
Compare the sensor reading with the ECU or switch settings.
Ask a qualified LPG technician to inspect the system if the problem remains unresolved.
Do not loosen multivalve fittings, open LPG tank connections or bypass safety components during diagnosis. LPG tank and multivalve work must follow applicable safety procedures.
Frequently Asked Questions
My LPG gauge is stuck on empty. Is the sensor dead?
Maybe, but don't buy another one just yet. Check the wiring and ECU settings first. A resistance mismatch or broken connection can look exactly like a failed sender.
Why does my LPG gauge show full after I've been driving for hours?
The display might be interpreting the resistance backwards, or the level mechanism might be stuck. Check the expected empty and full readings. Guessing based on the LEDs alone won't tell you much.
I replaced the LPG level sensor and nothing changed. What now?
Then stop swapping parts for a minute. Check whether the ECU is configured for the sensor you installed. Also inspect the connector and wiring. A new sensor with the wrong resistance curve can give the same bad reading.
Does every LPG sensor use the same resistance range?
Nope. Different systems can expect different values and signal directions. You need the actual resistance specification, not just a photo of a round sensor.
Can I connect a 12V LPG sensor to a 5V ECU input?
Don't do that without checking the circuit specifications. The stated voltage option and the ECU input must be compatible. A wrong connection can cause incorrect readings or electrical damage.
Is the LPG tank gauge supposed to show the exact amount of fuel?
Treat it as an estimate unless the complete system has a verified accuracy specification. Tank geometry, sensor calibration and the display electronics all affect the reading.
Replacement and Wholesale Requirements
To identify a suitable replacement, provide the original sensor image, right-hand multivalve details, connector specification, voltage and required resistance curve.
