2016 Chevy Colorado Z71
I have a 2016 Z71 with just under 45k miles on it. A couple of weeks ago my emissions gauge / check engine light came on my dash display. Also, my remote start stopped working (I guess as an extra indicator that I needed the truck serviced). The manual suggests that you have the truck serviced within 1 week if possible, and it’s a really smart idea to follow those instructions, not to cause further engine troubles. I took the truck to Autozone and they did a free diagnostic check which took less than 2 minutes. It showed just 1 error code for: P0442 - EVAP leak. There are a couple reasons this code will show up, from something as stupid as a loose gas cap to my problem which was a bad Canister Purge Valve (Solenoid). There is a simple way to check the part while it’s still on the truck to determine if it needs to be replaced. It took about 20 minutes to replace and saved an estimated $200-$250 by not having a mechanic do it. I attached a short how to video.
