Exhaust Temperature Sensor

Temperature / Air Pressure Sensor (TBAP)

Crankshaft Position Sensors (CPS)

The 5 tooth crank position sensor picks up all 5 flywheel teeth.

The 2 tooth crank position sensor picks up 2 off set flywheel
teeth.

Both crank position sensors will have a gap to the flywheel pick
up of 0.031" (0.8mm).

These sensors must be in the correct position or the engine will
not run as expected. A sheared flywheel key will cause the
engine to not start or kill if running.

The 2 tooth pick up detects the crank angle and obtains minimal
information of the crank angle when control enters into limp
home mode.

5 tooth pickup is to obtain the following information in
combination with the 2 tooth pickup.

• Judge direction of rotation (forward and backward)

• Ignition advance angle control

• Injector drive angle control 

• Excess advance ignition control at reverse

Capacitor Testing

1.

Charge the capacitor for 10 seconds using a 12 volt battery
by connecting the positive (+) lead to the Red/White wire
and the negative (-) lead to the brown wire.

2.

Monitor the capacitor voltage with a multimeter. The
voltage should slowly drain down from the initial charge.
If the cap does not hold a charge or drains rapidly, replace
the component.

Fuel Injectors

Fuel injectors are flow tested and then color coded (RED,
BLUE, or YELLOW) based on upon how much fuel the injector
flows during the test.

When replacing a faulty fuel injector, always replace with an
injector with the same color code. If replacing with an injector
with a different color code, all four fuel injectors must be

replaced with the new color so all four injectors are the same
color.

After replacing all four injectors, the ECU must be reflashed so
the fuel calibration map matches the new color coded fuel
injectors.

Reference Chapter 4 for fuel injector replacement procedures.
