Vtm-4 and check engine light on honda pilot

I've noticed that when it rains or snows my check engine and VTM-4 light comes on. In about a day or so they both will go away? What could this be???

The Honda Pilot's all-wheel-drive system is pretty clever, with variable torque distribution between its front and rear axles, as well as between the left- and right rear wheels. It generally works well and ensures strong traction on difficult roads - but some issues have been reported over the years. Their modes of operation are very similar, though, with the newer i-VTM4 essentially just adding more intelligence to the rear-axle torque distribution algorithms for improved agility and better stability in extreme driving conditions. But what if something goes wrong? First, let's look at what VTM-4 is. However, it's important to note that there is a clear distinction between the gauge-display-mounted VTM-4 or i-VTM4 warning light, and the confirmation light inside the dashboard-mounted VTM-4 switch, to the left of the audio system. The VTM-4 warning light in the Honda Pilot's instrument cluster should only illuminate when starting up the engine, following which it should extinguish within a second or so.

Virtual torque management system VTM-4 on 4-wheel drive Honda Pilot SUV automatically detects the traction conditions and distributes engine torque to the axles accordingly. Direct causes can be the low engine oil pressure, VTM oil temperature sensor, and damaged or improperly installed gasket. There can be indirect reasons like faulty oil pressure sensors, oil pressure switch, and exhaust gas recirculation EGR valve. You also need to check the condition of the transmission fluid to diagnose the real problem. VTM-4 is an automatic torque control system introduced by Honda. Road traction conditions change the applied torque to the rear axle to get optimum road grip on slippery or snowy surfaces. It remains active as soon as you turn ON the engine and automatically perform its function without driver input.
