Check Engine Light After Replacing Flat Tire
2015 BRZ - I got a flat tire on my left rear, threw on the spare and of course the Traction, ABS, and Check Engine lights were all on. Limped to the tire shop and replaced all 4 tires with new ones. Traction and ABS lights cleared a few yards after leaving the shop but the Check Engine light is still on. The engine seems to be running normally. Is this something I can clear myself or do I need to take it some place?
Thanks! |

If we don't know what it's for, we can't tell you. Go to an automotive shop and ask them to read the code. It's likely benign; can be cleared and forgotten

Codes. Always start with codes. The check engine light alone can be any one of about 170 error codes.

Thanks everyone, the code is a P2158 Speed Sensor B.
** Edit: The check engine light only came on after putting the spare on. I had to drive a little on the flat to get off the highway and that didn't trigger the light. So I'm wondering if this should eventually clear on its own, or if it needs to be cleared manually, or if the actual sensor is damaged. Last edited by Super Wabbit; 06-19-2023 at 03:55 PM. |

Try disconnecting the battery for 30 seconds. Or buy a code reader. I have an older Subaru (in addition to my FRS) so having a code reader is mandatory.

I've got a code reader now, so it's safe enough to try erasing it and seeing if it comes back?

Clear it and be done. Also read the manual, you never put the spare on the rear of a BRZ.

Cleared the code, engine seemed underpowered for a few miles but then went back to normal. No bode in about 100 miles. Thanks for the help everyone.
