NO Disconnect connector [79]. Leaving ignition control module disconnected, measure resistance between cavity 8 and cavity 5 [10B] (black) on Breakout Box. Also measure resistance between cavity 9 [11B] (gray) and cavity 5 [10B] (black) on Breakout Box. Is there still continuity to ground (less than 1 megohm resistance)? NO YES Replace CKP Repair short to sensor. ground on R or BK wire between connectors [10B] and [79B]. Set DVOM to AC volts and crank engine. Connect DVOM. At connector should read 1 VAC minimum while cranking. NO Replace CKP sensor. NO

Connect Breakout Box to harness only, leaving ignition control module disconnected. Measure resistance between cavity 8 [10] and cavity 5 [10B] (black) on Breakout Box and cavity 9 [10] (black) and cavity 5 of [10] (black) on Breakout Box. Is resistance more than 1 megohm? NO Check for intermittent connection, pinched or damaged wires, and loose CKP sensor fastener. Conditions found? NO Connect DVOM to cavities 8 and 9 at connector [10] on Breakout Box. Does DVOM read 1 VAC minimum during cranking? NO 3 [79] Terminals 1 and 2, DVOM Does it? NO YES Replace CKP sen- sor. Clear

CRANK POSITION SENSOR: DTC P0371, P0372,

YES Measure voltage on Breakout Box between cavity 8 [10] (+) and cavity 5 [10] (-) and also between cavity 9 [10] (+) and cavity 5 of [10] (-). Is voltage present? YES Repair as necessary. 4 sensor. Replace
1 2 NO Replace CKP sensor. YES With DVOM still connected, check for intermittents using 4.7 WIGGLE TEST. Intermittents present? YES Reinstall CKP ICM. Reprogram and perform pass- word learn.

YES Disconnect connector [79]. Measure voltage on Breakout Box between cavity 8 [10] (+) and cavity 5 [10] (-) and also between cavity 9 [10] (+) and cavity 5 of [10] (-). Is voltage present? YES Locate and repair short to voltage between red or black wires between connector [79B] and connector [10B] at ICM. YES Repair as necessary.
