Maintenance Tips of BYD 1373021600 Oxygen sensor for Song PLUS DM-i/Song PRO DM-i/YANGWANG U8/YANGWANG U8 PHEV/YANGWANG U8 HYBRID
- First, before replacing the BYD oxygen sensor (OE# 1373021600) in models like Song PLUS DM - i and YANGWANG U8, make sure the engine is completely cool to prevent burns.
- Use a specialized oxygen sensor socket to remove the old sensor. This helps avoid damaging the sensor body and ensures a smooth removal process.
- When installing the new oxygen sensor, apply anti - seize compound to the threads. This will prevent the sensor from seizing in the exhaust manifold, especially in high - temperature environments.
- Connect the electrical connector carefully. Ensure there are no loose connections as it can lead to inaccurate readings in BYD Song PRO DM - i and other models.
- After installation, start the engine and check for any error codes. The oxygen sensor should calibrate itself, but monitoring the system can help detect any potential issues early.
Warning: Do not over - tighten the oxygen sensor (OE# 1373021600) during installation. Over - tightening can cause damage to the exhaust manifold threads, leading to leaks and costly repairs.
