Monitor "CKP T/WHEELS-LO CMP" & "CKP T/WHEELS-HI CMP" parameters on the Scantool data list.
Specification :
"CKP T/WHEELS-LO CMP" : 38 +/- 4 tooth
"CKP T/WHEELS-HI CMP" : 98 +/- 4 tooth
Start engine and let vehicle idle
Connect scantool and select "Current Data" mode
Monitor "CKP T/WHEELS-LO CMP" & "CKP T/WHEELS-HI CMP" parameters on the Scantool 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
▶ Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification Vehicle Repair" procedure .
NO
Remove CKP and calculate air gap between sensor and flywheel/torque converter. Readjust as necessary and go to next step.
Air gap [0.3~1.7 mm [0.012~0.067 in] = measure distance from hosing to teeth on flywheel/torque converter (measurement "A") and from mounting surface on sensor to sensor tip (measurement "B") subtract "B" from "A"
If fail 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.
