Hi, have the B0951 code pop up with the check engine light and cannot find any reliable info online.

Thoughts?

Thank you!

Hello. Typically, a B code will not turn on the check engine light. I did manage to find a code description: DTC B0951 Headlamps on Indicator Circuit
Are your headlamps working properly? Both low and high?
If headlamp operation is normal, I would clear the code and retest. Turn the lights on and off several times and go from high to low multiple times to confirm operation. Please let me know how it goes.

Thank you, Sir! You are correct in that this probably isn't causing the idiot light as I do have some other engine issues to deal with.
I'm 99% sure my lights are all working correctly, one thing I did recently is replace the socket and lamp for the DRL on the passenger side. Is it possible to have the wires switched?
Thanks again for your assistance!

If you only replaced the DRL socket, you will be fine. According the the diagrams, it is a basic two wire socket.
