FUEL SYSTEM

6. Subtract the sensor length from the sensor mounting 6. Inspect the flywheel for corrosion, warping, and
point to encoder flywheel measurement. Verify that damaged or missing components.
the calculated air gap is within specification.
NOTE
MEASUREMENT
At this time measure flywheel run-out using a dial
CPS Air Gap: indicator near the teeth on the flywheel. If the run-out
1.0 ± 0.26 mm (0.059 ± 0.010″) causes the CPS air gap to be out of tolerance, identify
whether the flywheel is out of round, or if the crankshaft
is bent.

• If the resistance test, air gap test, and flywheel
inspection all test good, remove the flywheel and
verify the keyway is in good working order. If the
keyway is intact and problems persist, thoroughly
inspect the relevant wiring connections as a
electrical component or connection may persist. 4
7. Install the stator if removed (see Engine / Cooling
System chapter).
8. Install the stator cover if removed (see Engine /
Cooling System chapter).
9. Install a NEW or known good CPS. (see CPS
Replacement).
• If the resistance and air gap is correct proceed to 10.Fill and bleed the coolant system (see Engine /
Encoder Flywheel / Keyway Inspection. Cooling System chapter)
• If the air gap is incorrect, compare the CPS flange
to sensor face measurement to a known good
sensor. If the sensor is correct proceed to Encoder
Flywheel / Keyway Inspection.
• Is the CPS sensor is incorrect, follow the “CPS
Replacement” procedure.
ENCODER FLYWHEEL / KEYWAY INSPECTION
1. Access the CPS.
2. Disconnect the CPS from the main wiring harness.
3. Drain the coolant.

NOTE
Properly dispose of the coolant.

4. Disconnect the coolant hose at the water pump.
5. Remove the fasteners retaining the stator cover.
