⚠️ Common Signs of Failure

• Incorrect, unstable or missing data
• Implausible-signal or communication fault code
• Engine warning, derate or shutdown
• Open circuit, short circuit or internal electronic failure

🛠️ Service Notes

• Note the wiring and the sensor's orientation before removal, and isolate the circuit so nothing is live while the sender is out
• Check the float or probe moves freely through its full travel before fitting, and that nothing inside the tank or reservoir can foul it
• Seal the thread or flange as the installation specifies, and be sparing with sealant on a sender that earths through its body — an insulated sender reads nothing at all
• Do not over-tighten; these are thin-walled sensor bodies going into thin-walled tanks and housings
• Prove the installation end to end afterwards, confirming the gauge or alarm responds correctly at both ends of the range rather than assuming a new part must be good
