(2) Fully seat the sensor assembly in the engine. If the sensor assembly will
not fully seat into the engine, replace the sensor assembly.
(3) Install bolt (Figure 5, Item 4) and washer (Figure 5, Item 5) and tighten.
(4) Connect connector ENG-P4 to the primary (top) engine timing sensor
and connector ENG-P5 to the secondary (bottom) engine timing sensor.
Verify that the connectors are latched on both sides.
(5) Ensure that the harness is properly secured, and that the tie-wraps are
placed in the correct location. Proceed to STEP 7.
g. If one or both of the sensors are damaged, perform the following steps.
(1) Obtain a new sensor assembly.
(2) Lubricate each O-ring with engine oil.
(3) Fully seat the sensor assembly in the engine. Install the bolt and

(5) Connect connector ENG-P4 to the primary (top) engine timing sensor
and connector ENG-P5 to the secondary (bottom) engine timing sensor.
Verify that the connectors are latched on both sides.
(6) Ensure that the harness is properly secured, and that the tie-wraps are
placed in the correct location. Retest and verify that the problem is
resolved. Perform Engine Timing Sensor Calibration (WP 0013,
SYMPTOM 11). If the problem is not resolved, proceed to STEP 7.
STEP 7.
