Spark Overheating Bypass Valve Error

Hi, I've got a 2010 Chevrolet Spark, gasoline engine, with about 61000 km on it. I'm getting an error related to the bypass valve, and the engine seems to be overheating. I checked the coolant level, and it's fine. Any ideas?

A 2010 Chevrolet Spark owner reported an error related to the bypass valve and engine overheating, despite the coolant level being adequate. The issue was initially suspected to be related to a coolant leak, which could cause the engine to overheat and trigger sensor errors. However, upon further inspection, it was discovered that a faulty sensor was causing a false error message, and no actual repairs were needed.

Did this summary help you solve your problem?

I had a similar issue with my old Opel Corsa, though the error code was different. Turned out a coolant leak was causing the engine to work harder, leading to overheating and throwing off other sensors. It's like a domino effect; one thing goes wrong, and everything else follows. Have you checked for any coolant leaks around the engine or radiator?

Thanks for the tip. I'll check for coolant leaks more thoroughly. Where exactly should I be looking? Is there any particular area prone to leaking on these Sparks?

Unfortunately, I'm not familiar with the specific weak points of the Spark's cooling system. However, carefully inspect the hoses, radiator, water pump, and thermostat housing for any signs of leakage or dried coolant residue. If you're not confident, it may be prudent to consult a qualified mechanic to avoid further complications.

Thanks! It turned out to be a faulty sensor causing a false error message. No actual repairs needed, so 0€ spent! Appreciate the help.
