Consumer Description

Around 40k miles I received an Engine Maintenance Required warning. After some research Engine Maintenance and Engine Service Required are two very different indicators. I received and P2681 code meaning the electrical coolant bypass valve had failed unfortunately one can’t tell if it’s stuck shut or open this could lead to one’s care over heating and or damaging one’s engine. After some research I’ve come to find out most 2020-2024 corollas have been having this issue tends to happen about 30-50k miles
