What does it mean when the atoiltemp light comes on?

[SanMaci]

atoiltemp light is the transmission oil temperature warning light. Here are the relevant details: 1. When the light comes on: If it appears before inserting the key to start the vehicle, it's part of the self-check system and will automatically turn off after starting. 2. Meaning when illuminated: If the light comes on while driving, it indicates the transmission oil temperature is too high, and you should pull over to let it cool down. 3. Handling measures: This usually occurs during traffic jams or mountain driving. If it happens frequently, it's recommended to visit a 4S store to clear the code or upgrade the program. The existing active safety features in the vehicle's safety system ensure reliability during both normal road and off-road driving. When transmission oil temperature reaches 115°C, DTC (Diagnostic Trouble Code) will be set and information stored to assist technical analysis.

The oil temperature light on my car has come on several times. At first, I thought it was a false alarm, but it almost ruined the engine. Common reasons might be that the oil level is too low—I didn’t pay attention to checking it regularly, and didn’t even notice the leak. Or the oil pump could be faulty, failing to circulate oil for cooling, causing the oil temperature to spike. Another possibility is a stuck cooling system fan, leading to engine overheating. If the light comes on, don’t push it—pull over immediately, turn off the engine, wait a few minutes for it to cool down, then pop the hood and check the oil dipstick. If it’s low, add oil or call a tow truck—don’t attempt DIY fixes. Get into the habit of checking the dashboard before driving, and change the oil and clean the filter regularly to minimize such surprises.

When I used to drive an old car, I often encountered the engine oil temperature light flashing, mostly due to some system blockage. For example, the oil filter might be clogged with mud, restricting oil flow and preventing heat dissipation. Or the oil sensor could be faulty, giving false alarms when everything is actually normal. Another issue is the radiator fan not working; if the fan doesn't spin, it naturally can't cool the engine. When the light comes on, stay calm, immediately find a safe place to stop the car, and avoid accelerating or climbing hills to reduce the load. Check the oil dipstick—if the oil level is fine, wait for a repair shop to assist. I recommend keeping a spare bottle of engine oil for emergencies and checking the coolant and oil lines before long trips to avoid breakdowns on the road.

The oil temperature light typically signals that the engine oil is overheating, which can be caused by insufficient oil, a faulty oil pump, or poor cooling. If this occurs, you should stop the vehicle immediately to prevent engine damage from overheating. Regular maintenance can help prevent such issues, so it's important to frequently check the oil level.
