Test Procedure

  1. Turn ignition off. Thoroughly check CKP sensor. Also check for loose, bent, corroded, contaminated, deteriorated or damage CKP sensor and ECM connectors terminals. If sensor and connectors terminals are okay, go to next step. If sensor and connectors terminals are faulty, repair or replace as necessary and go to step  7 .
  2. Disconnect CKP sensor 3-pin harness connector. See Fig 1 and ECM 81-pin harness connector. See Figure . Measure resistance between CKP sensor connector terminal No. 1 (White/Yellow wire) and ECM connector terminal No. 15. Also measure resistance between CKP sensor connector terminal No. 2 (White/Green wire) and ECM connector terminal No. 34. Both resistances should be below one ohm. If resistances are as specified, go to next step. If any resistance is not as specified, repair open circuit as necessary and go to step  7 .
  3. With CKP sensor and ECM harness connectors disconnected. Measure resistance between ground and CKP sensor connector terminal No. 3 (Black/Yellow wire). Resistance should be below one ohm. If resistance is as specified, go to next step. If resistance is not as specified, repair open circuit at ground wire as necessary and go to step  7 .
  4. With CKP sensor and ECM harness connectors disconnected. Turn ignition on. Measure voltage between ground and CKP connector terminal No. 1 (White/Yellow wire). Voltage should be below 0.5 volts. If voltage is as specified, go to next step. If voltage is not as specified, repair short circuit as necessary go to step  7 .
  5. Turn ignition off. With CKP sensor and ECM harness connectors disconnected. Measure resistance between ground and CKP sensor connector terminal No. 1 (White/Yellow wire). Also measure resistance between CKP sensor connector terminals No. 1 (White/Yellow wire) and No. 2 (White/Green wire). Both resistances should be infinite. If resistances are as specified, go to next step. If any resistance is not as specified, repair short circuit as necessary and go to step  7 .
  6. Remove CKP sensor. Calculate air gap between sensor and flywheel/torque converter as follows:
    • Measure distance from transaxle bellhousing to flywheel/torque converterteeth. This is measurement "A".
    • Measure CKP sensor, from sensor mounting surface to sensor tip. This is measurement "B".
    • Subtract measurement "B" from measurement "A" = air gap. Air gap should be 0.037-0.067" (0.95-1.7 mm).

    If CKP sensor air gap is as specified, temporarily install a known good CKP sensor and check for proper operation. If problem is corrected, replace CKP sensor and go to next step. If CKP sensor air gap is not as specified, adjust sensor and check for proper operation. If sensor still not operating properly, temporarily install a known good CKP sensor and check for proper operation. If problem is corrected, replace sensor and go to next step.

  7. After repair, return vehicle to original condition. Clear codes using Hi-Scan Pro/Kia Data Pro Scan tool or equivalent. Verify repairs by driving vehicle and monitoring for pending codes. If DTC is set during test drive, follow appropriate DTC test procedure.
