Hi All,

I love my Chevy and I love the brand.
I am new here, I would like to ask for assistance regarding my Chevrolet Trailblazer 2017 (https://www.carsguide.com.au/car-rev...lazer-lt-50876)

1. I experienced a "Check engine light" last Tuesday.
2. I purchased a Bluetooth based ODB2 to scan the car.
3. Below are the error codes

I would like to seek your guidance on how to clear this error messages.

or do I need to purchase a new MAP sensor?

Having said that, I have tried searching for a compatible MAP sensor for my Trailblazer 2017, but I am troubled (too many search results, mostly Trailblazer 2009).
Will you be able to provide the part number?

I am unsure if this is the correct MAP Sensor for my vehicle

I believe this is quite 'advance' in terms of being a mechanic.
(I have performed several change oils, change bulbs..etc).

 

It does sound like the MAP sensor is getting flaky, but I don't know if that's the correct one or not.

 

Since this is not a North American vehicle, you might be better served by going to an Australian (Holden) forum and look for guidance there. Not trying to get rid of you, but just trying to get you the best information to assist you.

Good Luck!
