Injectors

• Solenoid valve-type injectors with lower power consumption and better response have

been introduced.

2 Connector

NOTE: Since the size of the injector connector is relatively big compared to the diameter of

the injector head, there might be an interference between the connector and the

injector seal during removal and installation of the cylinder head cover. In order to

prevent any damage to the seal, wrap vinyl tape around the injector connector

covering its edges.

• In addition, the leak-off lines of the injectors are located under the cylinder head cover.

As a result, the total leak-off amount of the injectors must be measured and compared to

the values of a known good vehicle in order to detect a leaking solenoid valve.

NOTE: Always replace the gaskets of the injector leak-off lines when removing them. As the

leak-off lines are located under the cylinder head cover, fuel leaking from the lines

can contaminate the engine oil. This results in engine oil dilution and hence in engine

damage.
