Check engine light came on after I replaced the spark plugs

Asked by Mar 03, 2019 at 05:10 AM about the 2009 Hyundai Sonata

Question type: Maintenance & Repair

I just replaced the spark plugs on my 2009 Hyundai
sonata and now my check engine light came on. I
went to get it scanned at an auto zone and they
told me I need a new map sensor.  No check
engine light was on prior to me changing the spark
plugs but I knew it was time to change them
especially that my car is pulling 327,000 miles. Did
I do something wrong when replacing the spark
plugs?

Not unless you accidentally disconnected the MAP sensor: check for a loose connection, or wires so deteriorated that they fell apart. With that many miles, there's no telling what's going to happen or when. If you want to prolong the life of this car, have a mechanic do a detailed diagnosis of the car. It probably won't cost more than $200, and you'll know where all the potential faults are.
