The first step is to check for related technical service bulletins (TSBs). The wiring and the connector of the sensor must be checked for damage, corrosion, loose pins, etc.
Why is my fuel ratio sensor not working?
Often a sensor gets contaminated or simply fails. In some cars, the heating element inside the sensor can stop working and cause the malfunction. For example, in many Toyota and Honda cars the code P0135 may be caused by a failed heating element inside the sensor. See how the heating element of the A/F sensor is checked in this article: code P0135 . In some cars, a sensor wiring may get shorted out after rubbing against metal parts. For example, in older Mazda 3, the sensor wire may rub against the bracket and short out causing the code P0131. When the engine computer detects that the air fuel ratio sensor signal is out of expected range it illuminates the check engine light.

How to diagnose a faulty fuel temperature sensor?
A technician will begin diagnosis of a faulty fuel temperature sensor by running a diagnostic scan with a scan tool connected to the vehicle's data port. The scan will not tell the technician if the sensor is bad, but it can reveal if the circuit for the sensor has a fault in it. If the scan is positive, the technician will access the sensor, unplug the harness wires, and test the sensor as well as the wire harness plugs. Using a multimeter, the technician will check the resistance reading of the temperature sensor. If the readings are off, the sensor needs to be replaced. If the readings are normal, the harness is checked for continuity with the multimeter.
How to tell if fuel temperature sensor is bad?
The most likely symptom of a faulty fuel temperature sensor is a check engine light.

In some cases, a failing fuel temperature sensor could lead to hard starting of the engine or an engine misfire and poor performance.
What is the difference between a cold and warm fuel temperature sensor?
When fuel is cold, it is dense and burns slowly. If it is warm, it is less dense and burns quickly. A fuel temperature sensor in a vehicle allows the Engine Control Module to constantly monitor the temperature of the fuel and adjust how much fuel is injected into the engine. The fuel temperature sensor is usually mounted on the fuel pump inside the fuel tank. A vehicle with a diesel engine may have a fuel temperature sensor located inside the injector pump or a fuel filter housing.
