Service Hint
Injection Pump Installation
Install the injection pump by aligning the matching mark on the injection pump with the reference position mark on the engine. Because the ECU recognizes the injection timing and makes appropriate corrections, it is not necessary to adjust the injection timing after assembly, as with the mechanical diesel pump.
SPV Inspection
Inspect the SPV by removing the connector and measuring the resistance between the SPV terminals.
TCV Inspection
Inspect the TCV coil by removing the connector and measuring the resistance between the TCV terminals.
Inspect the operation of the TCV by connecting the positive (+) and negative (-) terminals of the battery to the TCV terminals and checking the clicking sound of the solenoid.
