Cold Weather Starting

[ArcticHD8XTCab]

I have 2 defenders. a 2019 HD8 XT Cab and a 2022 HD10 Pro LTD. However the 2022 Pro LTD does not seem to like the cold compared to the old HD8. 

2019 HD8 XT Cab (on tracks) 

• Odyssey Battery PC1200 
• 0W40 Winter Can-am Oil 
• Start no problem -30C to -40C

2022 HD10 Pro LTD (on tires) 

• Odyssey Battery PC1200 
• 0W40 Winter Can-am Oil 
• Silicone pad oil heater 
• -35C to -40C hard time starting

I unfortunately do not have a garage, but leave the 2022 plugged in to a trickle charger and the pad heater overnight. Not sure if I am missing something or if others are trying other things. I have had my HD8 cold soak in -40C for days and still fire up. The only thing that comes to mind is the bigger engine needing more cranking power or the AC compressor causes a hard time cold starting? Any feedback or suggestions would be great. 

Thanks!

My 2019 HD10 XT Cab starts fine in the cold weather but I don't start it often at anything colder than -30C.🙂

One thing I do is prime the fuel system 3 times before I try to start in cold weather.

Does it fire then stall? Or do you have to crank it a lot before it fires up?

So I took this into our BRP guys here and apparently is the PPS sensor. At first I thought this was a throttle body sensor, but apparently its actually part of the gas pedal assembly. Supposedly its to prevent people from flooding the engine? Anway what I am told is the sensor has failed and is starving the machine of fuel not allowing it to start. So I am just waiting for this to come in now...... Frustrating from an otherwise great machine. For some reasons this has not been an issue on the 2019 HD8 XT Cab so I wonder if something changed or if this is a new sensor. But they said they have had a few of these in Defenders and Commanders not starting due to this.

Thanks for the update.
