How to Replace the Temperature Sensor on a Baojun 730?
2 Answers
When the temperature is low, it increases the fuel injection volume. Adjusts the ignition timing advance angle—increases it at low temperatures and retards it at high temperatures to prevent knocking. At low temperatures, the ECU controls the idle control valve based on the coolant temperature sensor signal to increase the idle speed.
Replacing the temperature sensor on a Baojun 730 is quite straightforward. I often encounter this issue during car maintenance, and my experience suggests starting with the basics: ensure the vehicle is parked on level ground, the engine is cooled down and turned off, and disconnect the negative battery terminal to prevent electric shock. The sensor is typically located near the radiator or on the side of the engine, requiring a wrench and gloves as tools. The steps involve unplugging the electrical connector, loosening the mounting bolt with a wrench to remove the old sensor; coolant may leak, so have a towel ready to absorb it. Then install the new part, ensuring the sealing ring fits properly, tighten the bolt, and reconnect the plug. Finally, top up the coolant, start the engine, and check if the temperature display on the dashboard is normal. The entire process takes about twenty minutes, with the key being to check each step, such as ensuring the sensor interface is free of corrosion to avoid future issues. If you're handy, you can handle it yourself, saving the cost of a repair shop visit.
