(3) Install the bracket bolt (Figure 3, Item 4) and washer (Figure 3, Item 5)
with bracket. Tighten the bracket bolt.
(4) Connect the sensor electrical connectors (ENG P401 to the crankshaft
(bottom) engine timing sensor and ENG P402 to the camshaft (top)
engine timing sensor (FO-2, Sheet 2). 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.

(5) Connect the sensor electrical connectors (ENG P401 to the crankshaft
(bottom) engine timing sensor and ENG P402 to the camshaft (top)
engine timing sensor (FO-2, Sheet 2). 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 8). If the problem is not resolved, proceed to STEP 7.
