In 2015, if the check engine light in your GMC Terrain comes on, it could be due to various reasons. Common causes include low oil levels, abnormal emissions from the gas tank or exhaust pipe, and issues with sensors like the oxygen sensor and catalytic converter. It's crucial to promptly have your vehicle diagnosed once the light turns on. An OBD-II reading can identify fault codes that help you pinpoint the problem. Once the issue is resolved, the light should go off. If it remains on, you can use an OBD-II reader to turn it off.

I changed the oil sensor for the intake and exhaust, and it worked for four weeks before the issue reappeared.
