Due to its electronic sensitivity and calibration requirements, proper installation is crucial.
Power Off: Disconnect battery negative terminal to prevent short circuits.
Inspect Intake Manifold: Ensure mating surface is clean, flat, and free from carbon buildup or debris.
Check Electrical Connector: Look for bent pins, corrosion, or moisture ingress.
Verify New Unit Condition: Confirm packaging seal and scan QR code (if available) for authenticity.
Remove old throttle body by loosening mounting bolts.
Clean intake flange thoroughly using non-residue cleaner.
Install new gasket or sealing ring — never reuse old seals.
Mount the new 1005098929 unit and tighten bolts evenly (torque: ~8–10 Nm).
Reconnect electrical harness securely — ensure locking clip clicks into place.
Reconnect battery and turn ignition ON (do not start engine yet).
❗ Critical Step – Perform Initialization Learning (Throttle Adaptation)
After replacement, the ECU must relearn the throttle's idle and full-open positions.
Required tools:
Original diagnostic device (e.g., Weichai ZhiDuoxing / "Wisdom Star", Delphi DS150E, or Sinotruk EOL tester)
Software access to perform “Throttle Body Initialization” or “Adaptive Reset”
Procedure typically includes:
Ignition ON, engine OFF
Enter service menu → Select “Throttle Learning”
Follow prompts until completion (~2–5 minutes)
⚠️ Failure to complete this step will result in:
Check Engine Light (CEL) illumination
Reduced power mode ("limp home")
Poor idle stability or unresponsive accelerator
