JA18 - Check For CKP+ Shorted to CKP - Resistance Low Fault
- Key Off.
- Disconnect CKP sensor from vehicle harness connector.
- DVOM on 20K ohm scale.
- Measure resistance between J35 (CKP+ I) and J48 (CKP- I) at breakout box.
- Is resistance greater than 3K ohms?
YES -- REPLACE CKP sensor. Shorted sensor windings. REMOVE all test equipment. RECONNECT all components. Clear continuous memory. Clearing Diagnostic Trouble Codes
Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
NO -- CHECK connectors. SERVICE or REPLACE harness. CKP+ shorted to CKP-in harness. REMOVE all test equipment. RECONNECT all components. Clear continuous memory. Clearing Diagnostic Trouble Codes
