water temp gauge motorhome not working

• 2023-03-30

Is there a problem with the thermostat , the motorhome water temp sensor, and the grounding of the circuit? If there are any of the above problems , they are easy to repair and don't cost much. If there are no problems with these factors, then only a single water temperature gauge can be replaced. Generally, the failure probability of the water temperature gauge is relatively small, and replacing it is very cheap.

When the vehicle motorhome water temperature sensor fails, the engine intake system can only supply the engine with a thinner mixture (signal when the vehicle is hot). This can cause the engine to be cold and difficult to start. If the motorhome water temp sensor fails, the indicator needle of the motorhome water temp gauge will not move, making it difficult to start a cold car, and increasing fuel consumption . The indicator needle of the water temperature gauge does not move and points to the highest position . It is difficult to start a cold vehicle because of a water temperature sensor fault. When starting a cold vehicle , it also displays a temperature signal from a hot vehicle. The ECU cannot receive a signal of excessive rich mixture, and can only provide the engine with a thinner mixture. Fuel consumption increases, idle speed is unstable , acceleration is difficult , the accelerator pedal is fully depressed, and the engine speed does not increase.

When the motorhome coolant undergoes a small cycle, it does not pass through the radiator tank, which is conducive to rapid engine temperature rise. When the motorhome engine of an old Ford truck reaches its normal operating temperature, the coolant will undergo a major circulation, and at this time, the coolant needs to pass through the radiator tank to dissipate heat. There are water temperature sensors in the engine. If the motorhome water temp sensor is damaged, the water temperature gauge on the instrument panel will not respond. The engine coolant needs to be changed regularly, and the typical household car needs to change the coolant every two years. If the coolant is not changed for a long time, the boiling point will drop and the freezing point will rise. When there is a lack of coolant in the engine, never use tap water instead. Tap water contains minerals that can easily form scale when exposed to heat.
