Timing Control Valve (TCV)
The timing control valve (hereafter referred to as “TCV”), which is mounted
on the injection pump,
opens and closes the fuel passage between the high-pressure and low-pressure chambers of the
timer piston in accordance with the signals from the computer.
When current is applied to the coil, the stator core becomes magnetized and retracts the moving
core by compressing the spring. As a result, the fuel passage opens.
The opening of the valve is controlled by the computer in accordance with the ratio of the ON/OFF
times (duty cycle ratio) of the current that is applied to the coil. The longer the length of the ON time,
the longer the valve remains open.

Возможные причины:
•Wiring harnesses and
connectors (TCV signal
system)
•Timing control valve
•Clogged fuel filter
•Fuel (frozen, air intermixed)
•Injection pump
•Engine control computer
Данная ошибка не означает безоговорочную уверенность в том, что неисправен именно TCV.
Посмотрите управление на него и если оно есть, то снимите и почистите
