Maintenance Tips of BYD 1228280100 Throttle body for Qin PLUS DM-i/Song PLUS DM-i/Song PRO DM-i/KING DM-i/Chazor DM-i/Seal5 DM-i/Destroyer 05 DM-i/DENZA D9 DM-i/DENZA D9 PHEV/DENZA D9 Hybrid
- First, before removing the throttle body (OE# 1228280100) on BYD Qin PLUS DM-i and other models, disconnect the battery to prevent electrical short - circuits.
- Next, clean the throttle body thoroughly using a specialized throttle body cleaner. This helps improve air - fuel mixture and engine performance.
- Then, when reinstalling, ensure the throttle body gasket is in good condition. A damaged gasket can cause air leaks and affect engine operation.
- After that, check the throttle position sensor (TPS) calibration. Incorrect calibration may lead to poor acceleration and rough idling.
- Finally, reconnect all electrical connectors firmly. Loose connections can cause intermittent throttle response issues.
Caution: Do not overtighten the bolts when installing the throttle body (OE# 1228280100) on BYD models, as it may damage the throttle body or the intake manifold.
