If your car is running fine and the temperature gauge shows normal operating temperature, it is unlikely that the P0128 coolant thermostat code would be triggered during a smog test, even if the air conditioner is on. The P0128 code indicates that the engine is running too cool, which can cause problems with fuel economy and controlling emissions. If your car is not experiencing any symptoms of a P0128 code, such as a check engine light, longer warm-up time, or reduced fuel economy, it is unlikely that the code would be triggered during a smog test.
If you've received a P0128 code, it's advisable to have your vehicle inspected by a qualified mechanic. They can perform diagnostic tests to determine the root cause of the issue. This may involve checking the thermostat, the cooling system, the coolant temperature sensor, and other related components to ensure that everything is functioning correctly.
