CEL light code p0126

[Jarpee28]

CEL came on today on my 13 GT CX5, ran by autozone and had diagnostics which said it was p0126. I will go to the dealer tomorrow to let them see it. I have been reading other posts about this issue and it seems an engine software reflash is all that is needed, at least on the 14s. Should I be expecting them to say anything else about it tomorrow? I will post back with an update after I go in tomorrow.

That's a engine temperature sensor issue. They'll replace the sensor, really cheap.

It is not a serious issue. If it is more than simply adjusting preset engine parameters (ECU flash), it is either a faulty ECT sensor, like already mentioned, or a t-stat that is stuck open.
Considering the track record with this issue, I would anticipate nothing more than an ECU reflash.

It was a reflash that was needed. Just left the dealer. Thanks for the replies.
