I have a 2018 Chevy Equinox Premier with the 2.0 turbo engine. During a long drive through some seriously crappy weather the other day I got a Reduced Engine Power message on my DIC and a check engine light. It was snowing so hard it was a whiteout, about 4 inches of snow on the road, a serious head wind, and I was following other traffic so there was lots of blowing snow. I had been driving in these conditions for about an hour before I got the CEL.
I pulled over and had the following codes:
P0237 : Turbocharger Boost Sensor Circuit Low Voltage
P0299 : Engine Underboost
P2227 : Barometric Pressure (BARO) Sense 1 Performance
In looking at the front of the car it was totally packed with snow so I figured maybe it was a problem with the air intake. I sat for about 20 minutes hoping it might thaw out a bit. Engine temp was stable but running just under 220 instead of the normal ~200. I ended up clearing the codes and continuing through the shitty conditions. On restart everything was fine with no codes for about 40 minutes when I got the same conditions. When driving I was very light on the throttle and did not step into the gas pedal it did seem to help the situation.
Eventually the snow slowed down, the roads cleared up, I lost the headwinds and the problem went away. I drove for about an hour stepping into the pedal on a regular basis and didn’t see the problem again.
For aerodynamics I know the Equinox sucks air from down below (bottom feeder) and was thinking snow pack might have limited air intake and caused these codes.
I had a POS vehicle when I was in college and under similar conditions used to put a piece of cardboard in front of the radiator. lol
Has anyone heard of a similar issue?
