Alright, is the check engine light still on? Scan for the codes again, what is the number code or codes that pop up? Just replacing a part as you found out doesn't always fix the issue. You might have other issues, like a leak in one of the vacuum hoses causing the issue. Post your answer below.

Exactly , don't make assumptions , the problem erupted by pure coincidence and may not have been the sensor . The code tells you where the problem is not always what to replace ,
