Where is the 2019 Mazda 3 OBD port?

The Check Engine light just came on in my 2019 Mazda 3, and I want to investigate the issue, but the OBD port is nowhere to be found. I’m handy when it comes to mechanics, but this one is a mystery to me. Where can I find the OBD port in a Mazda 3?

While a
Check Engine warning light
can raise eyebrows, it’s not always an issue to be alarmed about. Scanning your 2019 Mazda 3 for problems is a wise move either way, and you can find the OBD port at the bottom left of the steering wheel, at the right of the hood opening command.
It can be tricky to spot, and it might be even harder to
understand car OBD codes
without solid experience. However, it sounds like you have some
car repair
chops, so you should be good to go! Check out these typical codes that trigger the Mazda 3’s Check Engine light just in case:
  • P1001: Unable to complete self-test function or SCP error
  • P1120: Throttle position sensor is out of range or low
  • P1195: EGR boost sensor circuit
  • P1196: Ignition switch start circuit error
  • P1235: Fuel pump control circuit error
If any of these codes pop up and you’re not sure how to handle them, it’s best to
take your car to a repair shop or mobile mechanic
for a better assessment. An experienced mechanic’s input is valuable, especially if you have an
extended car warranty
