Component Inspection

Start engine and let vehicle idle.
Connect scan tool and select "Current Data" mode.
Monitor "CKP T/WHEELS-LO CMP" & "CKP T/WHEELS-HI CMP" parameters on the Scan Tool data list.
Specification:

"CKP T/WHEELS-LO CMP": 38 +/- 4 tooth

"CKP T/WHEELS-HI CMP": 98 +/- 4 tooth

Are "CKP T/WHEELS-LO CMP" & "CKP T/WHEELS-HI CMP" parameters within the specification?
YES:
- Thoroughly check connectors between CKPS and ECM for loose or poor connections, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO:
- Remove CKP and calculate air gap between sensor and flywheel/torque converter. Readjust as necessary and go to next step.
NOTE: Air gap [0.3~1.7 mm [0.012~0.067 in] = measure distance from housing to teeth on flywheel/torque converter (measurement "A") and from mounting surface on sensor to sensor tip (measurement "B") subtract "B" from "A".
- If failure to synchronize with CMP sensor, readjust timing system and go to next step.
  Check CKP sensor for contamination, deterioration, or damage. Substitute with a known-good CKP sensor and check for proper operation. If the problem is corrected, replace CKP sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
