Yes, on some vehicles it can.
How can I check the ENGINE COOLANT TEMPERATURE (ECT) sensor on my 1991 HONDA PRELUDE SI 2.1L
Yes, a check engine light can come on if a coolant temperature sensor is faulty. The sensor provides critical data to the engine control unit (ECU) about the engine's temperature, which is essential for optimal performance and emissions control. If the sensor malfunctions, it can trigger error codes, leading to the check engine light activating. It's advisable to have the vehicle diagnosed to determine the exact cause.
yes
Yes, low water levels in the cooling system can potentially cause the check engine light to illuminate. When the coolant level is too low, it may lead to overheating, which can trigger the engine's temperature sensors and activate the check engine light. Additionally, some vehicles have sensors specifically for monitoring coolant levels, and if they detect a problem, they may also signal a check engine light. It's essential to address low coolant levels promptly to prevent engine damage.
Hey Ken==Check the coolant in the radiator WHEN THE ENGINE IS COLD. Sometimes the coolant recovery bottle wilpopiooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool still have coolant but the rad low. GoodluckJoe
water pump, oil, water, engine coolant....main cause would be engine coolant, just check to see if you have a leak.
Blown head gasket will do it check your coolant for oil in it and your engine oil for coolant it it...
After coolant is added run vehicle to normal operating temperature and re-check coolant level
it is low coolant temperature, could be the thermostat could be the sensor for coolant temperature.
The engine is overheating. The check engine light is not on because you have no problem with the emissions system which this light monitors.
On a 1997 Ford Explorer : CHECK ENGINE is just to the left of the " C " on the engine coolant temperature gauge ( Helpfull )
Check your oil and see if coolant has leaked into the engine...A known problem with 3.8L engines are defective intake manifold gaskets that allow coolant into the engine block. Costly repair.
