Engine Overview and Common Failures
The weight of the 1CD-FTV engine according to the catalog is 205 kg. The engine number 1CD-FTV is located at the junction of the block and the cylinder head. The main malfunctions of the fuel system are related to injectors, as they quickly wear out due to abrasive wear caused by impurities in the diesel fuel. Only refuel at trusted stations, regularly change the fuel filter, or be prepared to spend a significant amount on their replacement. Even used ones are quite expensive. Valve leaks SCV Two special valves, SCV, are responsible for regulating fuel delivery to the fuel injection pump (TNVD) and over time, they tend to develop leaks. Initially, the idle speed fluctuates, and then the engine stalls or refuses to start. In general, monitor the condition of the TNVD. Oil pressure sensor glitches The most well-known weak point of the power unit is the oil pressure sensor. At some point, the ECU unexpectedly signals a low oil level, although it is not true. The problem can only be radically solved by replacing the sensor. EGR valve contamination On high mileage, the EGR valve often gets clogged and stuck in one position. Initially, this results in a loss of power, but then the engine goes into emergency mode. Low service life of the water pump An unreliable water pump is found in many Toyota engines, and this diesel is certainly no exception. It can start leaking even at mileages of 50 - 60 thousand kilometers.
