P0100 on Your 2024 Chevrolet Traverse
A P0100 code on your 2024 Chevrolet Traverse indicates the ECM has detected a malfunction in the mass air flow (MAF) sensor circuit. The completely redesigned 3rd-generation Traverse features the new 2.5L turbocharged four-cylinder engine—a departure from the previous V6—and this code is uncommon on a new vehicle.
Symptoms
- Check engine light on
- Rough or unstable idle
- Hesitation during acceleration
- Reduced power
- Poor fuel economy
- Possible stalling
Likely Causes
