JA51 - Check CKP Sensor Resistance - CKP Circuit Fault

- Key Off.

- Disconnect ICM from ICM tee, leave EI diagnostic harness connected to vehicle harness connector.

- DVOM on 20K ohm scale.

- Measure resistance between J47 (CKP- I) and J48 (CKP+ I) at breakout box.

- Is resistance between 2300 and 2500 ohms?

YES -- REPLACE ICM. REMOVE all test equipment. RECONNECT all components. Clear continuous memory. Clearing Diagnostic Trouble Codes

Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes

NO -- Go to JA43. Resistance fault. JA43 - Determine If Resistance High or Resistance Low Fault
