Code No. P1021: Oil Feeder Control Valve System
OPERATION
• Power is supplied to the oil feeder control valve
(terminal No. 1) from the engine control relay (ter-
minal No. 4).
• The engine-ECU <M/T> or engine-CVT-ECU
<CVT> (terminal No. 52) makes the power tran-
sistor in the unit be in ON position, and that
makes currents go on the oil feeder control valve
(terminal No. 2).
