Check engine light

[trek777]

My 2014 CX-5 Sports check engine light has came on. I pulled the code to see if it was anything serious and it's PO128. The definition that my code reader gave said something about the engine not getting up to operating temperature. Which I think is strange because the blue light still comes on and goes off after a couple of miles like it always has.
I'm going to get it to a dealership as soon as I can, but that won't be for a couple of weeks.
Has anyone else had this code and if so what did the dealership do?

There is approximately 6 possible causes for the P0128 including Low Coolant level.

if you had it since 2012 or 2013 check your coolant level. mine was 1L low in the reserve.

I checked the coolant level and it isn't low.

A couple of weeks ago I finally got around to getting to the dealership and on my drive over there the light went off. Their Mazda tech had left for the day so they couldn't look at it and since the light was off I wasn't worried about it. A couple of days later the light came back on then shut off again and then about a week later it came on and stayed on. I went to the dealership and there was a TSB that covered that code. Certain Mazda 3s and Cx5 have to have the PCM reprogrammed for this issue. It didn't take to long and so far the light is off.

It would be helpful if you update your vehicle info to include model year, but I would bet yours is a 2013 as there were a few reports of this kind of thing early on in the forum.

Sound like what I mentioned in the open recall tread
