Can you drive with the cold engine light on?
While you can still drive the vehicle safely with this light on, it is best to wait until the blue light has turned off. The light should only stay on for a minute or two, unless it is extremely cold outside, then it may take a minute or so longer to go out.
What is the cold engine light really telling me?
Engines run safely and effectively in a temperature range which is actually fairly narrow. The temperature gauge (or cold and hot indicator lights) typically measure the temperature of the engine coolant itself. When the car is first started, the engine is cold, and oil will need time to heat up and achieve good flow for lubrication.
Why does my engine temperature stay on cold?
Reasons Why Your Engine Temperature Gauge Stays on Cold. 1. Faulty Engine Coolant Temperature Sensor. 2. Faulty Gauge/Cluster. 3. Broken Wires to the Sensor Or to the Gauge. 4. Bad Thermostat.
When does the engine temperature warning light come on?
When working properly, the cooling system keeps the engine running at peak efficiency and at its ideal operating temperature. Upon starting, the engine temperature warning light should come on and then go off in two seconds or less. But if it stays on, or comes on while you’re driving, there’s a problem.
What is the temperature of the coolant in an engine?
If your car model has two coolant temperature sensors, one is used by the temperature gauge, and one is used for the engine control unit. Engine temperature sensors are easy to measure with a multimeter, but you need to find the right values of them.

Why is my engine temperature reading so cold?
The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself which is sending the information to the cluster.
