FUEL INJECTOR
FUEL INJECTOR
Component Description INFOID:0000000004500409
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

1. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with
a box wrench securely. Then move the wrench handle in the
direction of arrow (loosening direction of tensioner).
WARNING:
Never place hand in a location where pinching may occur if
the holding tool accidentally comes off.
2. Insert a rod such as short-length screwdriver approximately 6 mm (0.24 in) in diameter into the hole (B) of retaining boss to fix
drive belt auto-tensioner.
3. Install drive belt. CAUTION:
• Confirm drive belt is completely set to pulleys.
• Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-136, " Checking Drive Belts " .
