10. Rotate engine two revolutions to take up slack in timing chain and return No. 1 cylinder to its
compression stroke.
11. NOTE: No. 1 cylinder must be at 26 degrees After Top Dead Center (ATDC) to set CID sensor.
Verify that No. 1 cylinder is on its compression stroke (both valves closed).
12. Continue to rotate the crankshaft until the new 26 degrees ATDC mark lines up with the timing
pointer.
13. NOTE: The voltmeter will register battery voltage whenever the CID sensor closes and makes
a complete circuit.
While rotating the CID sensor, note the exact point where the sensor switches from 0 to 12 volts on
the voltmeter.
14. NOTE: The final movement to set the CID sensor must be in a COUNTERCLOCKWISE
direction.
Rotate the CID sensor clockwise past the CID switching point (from 12 to 0 volts).
15. Rotate the CID sensor counterclockwise and stop at the exact point the voltmeter switches from 0 to
12 volts.
16. Tighten the CID sensor hold-down bolt to 17-21 Nm (13-15 lb-ft) using Sensor Adjusting Wrench
T94T-12270-A.
17. Disconnect the testing wiring harness and the voltmeter and install wiring harnesses, emission control
system, fuel system, ignition system and front end accessory drive components, by referring to
procedures in the specific sections.
