Fuel temperature sensor 9307-529A JCB 444, OEM

Fuel temperature sensor 9307-529A is an OEM part for the machines with the JCB Dieselmax 444 engine. According to the product card, this is the fuel temperature sensor of fuel pump 320/06620.

A temperature sender measures coolant or oil temperature and passes it to the instrument panel, triggering a warning when the temperature exceeds a set value. The resistance of the thermistor inside the sender changes with temperature, and the gauge shows this as temperature. A faulty sender makes the gauge read constantly low or high, sets off a needless overheat warning or misses real overheating. Before replacing it, check the coolant level, thermostat and radiator; the sender can be verified by measuring its resistance at different temperatures. Scale and deposits on the sender tip slow the reading, so using the right antifreeze in the cooling system also helps the sender read accurately.

Specifications

Compatibility

According to the product card, 9307-529A is a fuel temperature sensor. Fit is confirmed by the part number. Other parts are in Sensors and valves.

Fitting

Moisture and corrosion inside the connector are a common cause of false signals from sensors and switches, so clean the connector and use contact spray if needed. Renew the connector seal if it is missing. The part is chosen by part number, and its connector type is compared with the old part.
