It is normal for the Geely Panda's temperature gauge to show 9. Here is the relevant introduction: Coolant sensor: The coolant sensor in the Geely Panda is an essential component in engines using a three-way catalytic converter to reduce exhaust pollution. Air-fuel ratio of the mixture: Since the purification capability of the three-way catalyst for CO, HC, and NOx drops sharply once the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust and send feedback signals to the ECU. The ECU then adjusts the fuel injection amount of the injector to keep the air-fuel ratio of the mixture near the theoretical value.
