Will the engine water ingress warning light come on?

[VonEmily]

Engine water ingress warning light will not come on. The reasons for the engine warning light to illuminate are as follows: 1. Fuel quality issues: The fuel quality does not meet the standard. Some car owners may see the engine warning light illuminate immediately after refueling, which is usually caused by filling with poor-quality fuel at non-standard gas stations. 2. Carbon deposits in the engine or spark plugs: After some time of use, the engine will accumulate carbon deposits, which can cause engine damage, starting difficulties, poor acceleration, excessive engine noise, and other phenomena. 3. Damaged coolant temperature sensor: If the coolant temperature sensor does not send cold engine state information, it will cause the air-fuel mixture to become lean, leading to abnormal engine operation. Similarly, if it sends cold engine information when the engine is warm, it will cause the air-fuel mixture to become rich, and the engine will also operate abnormally.
