It got colder here in Winnipeg Canada these past few days, and as such I started plugging the block heater in. Anyway, today I noticed the Check Engine Light on, and I pulled the code right away: P011A - POWERTRAIN - Engine Coolant Temperature Sensor 1/2 Correlation
I see that this code is associated with a bulletin for slightly older CX-5's: https://mazda.oemdtc.com/361/check-...when-starting-in-cold-weather-2012-2016-mazda
I'm wondering if any other CX-9 owners have come across this and how they may have diagnosed or fixed this.
I'm not really seeing any other symptoms. Since I'm working from home my drives tend to be real short, like about a kilometer as we just take the kids to school every day. I did find that the engine takes a while to warm up, however, in that short of a drive, I'm thinking most cars would take a while to warm up in -20C weather. It does eventually blow hot air and I've never seen it overheat. I don't believe it's a heater core blockage or anything, but maybe a stuck-open thermostat, if that can cause such a code I don't know. Anyway, I'd say the car runs fine, it's just this code has me puzzled.
Btw, I bought this car used on Jan 5, 2021 with around 98,000Kms.
