If complaints are made with these vehicles that the engine warning light (MIL) comes on and if the P0180 fault code is also stored in the fault code memory, a possible cause of the problem can be traced to bad contact on the fuel temperature sensor.
The P0180 fault code is the same as the malfunction in question: (Circuit, cable harness, fuel temperature sensor, engine control unit).
In addition, the fuel filter housing is to be visually checked for various points including the date of manufacture (Photo / label, see dotted arrow). If the date code is 2835, the fuel filter housing is to be replaced.
