2002 Hyundai Accent GL, AutomaticFACTORY OEM SERVICE PROCEDURE

Test Procedure

  1. Turn ignition off. Connect Hi-Scan Pro tool or equivalent to OBD-II Data Link Connector (DLC). See Figure. Turn ignition on. Monitor for DTCs. Verify DTC P0335 or P0336 are set and go to next step.
  2. Turn ignition off. Disconnect CKP sensor 2-pin harness connector. See Fig 1. Measure resistance between CKP sensor terminals No. 1 and 2 (component side). Resistance should be 486-594 ohms at 68°F (20°C). If resistance is as specified, go to next step. If resistance is not as specified, replace CKP sensor with known-good component and go to next step  6.
  3. Disconnect ECM 81-pin harness connector. See Figure. Measure resistance between ground CKP sensor connector terminal No. 1 (White wire) and No. 2 (Brown wire). Both resistances should be infinity. If resistances are as specified, go to next step. If any resistance is not as specified, repair short circuit (in White or Brown wire) between CKP sensor and ECM. After repair go to step  6.
  4. With CKP sensor and ECM harness connector disconnected, measure resistance between CKP sensor connector terminal No. 1 and ECM connector terminal No. 34 (White wire). Also measure resistance between CKP sensor connector terminal No. 2 and ECM connector terminal No. 15 (Brown wire). Both resistances should be one ohm or less. If resistances are as specified, go to next step. If any resistance is not as specified, repair open or short circuit (in White or Brownwire) between CKP sensor and ECM. After repair go to step  6.
  5. Verify than CKP sensor and ECM connectors are secure. If connectors are okay, replace CKP sensor with known-good component. If after sensor replacement problem persists, replace ECM and go to next step.
  6. Return vehicle to original condition. Clear codes using Hi-Scan Pro 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.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
