P202A FORD Description
The tank heater is located in close proximity to the tank temperature sensor. Therefore the tank temperature sensor can be used to monitor the tank heater performance.
When the tank heater is activated, the tank temperature is expected to rise. If this is not the case a fault will be set. If the vehicle is operated for several consecutive short drive cycles, the test may require more than one drive cycle to complete.
