Service Engine Light

I had a crankshaft sensor replaced February 5, 2019. The “service engine light” stayed off for a week, came back on February 15th. My mechanic changed another sensor (not sure what sensor) on Feb. 15th. Service engine light came on again in March. He cleaned the battery terminals and the service engine light didn’t come on again until April 1st. He turned the “service engine light” off and told me to let him know if it comes back on. The service engine light came on yet again Sunday, April 14th as I was leaving Sunday morning church service. I haven’t been able to get in touch with my mechanic due to some phone problems on his end.
This “service engine light” problem is really becoming a problem with me. The mechanic told me my car has between 30 – 40 sensors. Don’t know if this is true or not. I know my car is old but I like it and can’t afford to replace it. Do you have any suggestions as to what might be causing the “service engine light” to continue coming on?

Welcome to 2CarPros.

There are many sensors on today's vehicles. However, when the check engine light comes on, it will provide a diagnostic trouble code indicating where the problem is coming from. If by chance you have that code, let me know what it is.

Now, if the light is on but the car continues running properly, chances are it is related to the Evaporative Emissions System (EVAP). What I need you to do is get the codes for me. First, here is a quick video showing how it is done:

I realize most people don't own a scanner. However, most nationally recognized parts stores will do it for free and tell you the codes. Also, often times they will lend or rent the tool needed. I need you to have that done and let me know what is found.

I will watch for your reply.
