THE FIX OF THE WEEK SEPTEMBER 8TH, 2020

Every week, we review new fixes submitted by our Direct-Hit users and pick our favorite “Fix of The Week.” These are confirmed, experience-based fixes directly from technicians and shops. You can find this and more than 3.5 million other confirmed fixes in Direct-Hit with a 14-day free trial. This week, our favorite fix is for a 2012 Chevrolet Cruze with the vehicle going into fail safety mode.

The Vehicle:

2012 Chevrolet Cruze

The Problem:

The ECM is setting P2227 Barometric Pressure (BARO) Sensor Performance trouble code – Vehicle goes into fail safety mode

The Diagnosis:

I used Direct-Hit to search the issue by running a diagnostic with the scanner. Direct-Hit indicated that BARO, MAP and Boost Sensor should have the same PSI reading with the key on and the engine off. The sensors all read the same even though the vehicle was not running a 14.2 PSI. When I drove the vehicle at part throttle, the BARO sensor dropped to 12 PSI. The BARO sensor reading should have stayed the same unless the altitude changed, but it did not. I had to remove the front bumper to access the air intake duct. Once removed, I saw a nest of leaves from a rodent that was blocking the air-intake duct. Once I removed the nest, the BARO never dropped below 14.2 PSI again.

The Solution:

Cleaned the air intake duct
