FUEL INJECTOR
2007 Versa
FUEL INJECTORPFP:16600
Component DescriptionUBS00PTO
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.
CONSULT-II Reference Value in Data Monitor ModeUBS00PTP
Specification data are reference values.

Checking Drive BeltsEBS00U70
WA RN ING:
Be sure to perform this step when the engine is stopped.

Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (A).
NOTE:

Check the drive belt auto-tensioner indication when the engine is cold.

When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B).

Visually check entire drive belt for wear, damage or cracks.

If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentEBS00U71
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationEBS00U72
REMOVAL
1. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with
a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
CAUTION:
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 the retaining boss to
fix drive belt auto-tensioner.
3. Remove drive belt.

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-13, "
