P0175 on the 2022 Chevrolet Camaro
The P0175 code on your 2022 Camaro signals that Bank 2 is running too rich. The 2022 Camaro offers the 2.0L Turbo four-cylinder (275 hp), 3.6L V6 (335 hp), 6.2L LT1 V8 (455 hp SS), and the supercharged 6.2L LT4 (650 hp ZL1). Bank 2 on V-configuration engines is the passenger side. At 20,000-40,000 miles on a 2022 model, P0175 is more likely a contamination issue or early component failure than normal wear.
Late-Production Camaro
The 2022 Camaro is near the end of the sixth-generation production run, with the Camaro being discontinued after 2024. These engines are mature and well-sorted. P0175 at this mileage is typically an individual component issue. The performance-oriented nature of the Camaro means many owners modify their cars, which can introduce additional diagnostic variables.
Symptoms
- Check engine light active
- Fuel economy worse than rated figures
- Black exhaust visible during aggressive driving
- Idle quality reduced
- Throttle response feels dulled
- Exhaust popping on overrun
- Fuel odor from tailpipe
Top Causes
1. MAF Sensor Contamination
The number one suspect, especially if the Camaro has an aftermarket intake or oiled filter. Even with the stock intake, PCV blow-by from spirited driving contaminates the MAF. A ten-minute cleaning job with $10 of spray can resolve the code. This should always be your first step.
2. O2 Sensor Issue
At lower mileage, a failing sensor may be premature. If the car is driven aggressively or tracked, the higher exhaust temperatures can accelerate sensor wear. The Bank 2 upstream sensor on the V8 sits in the passenger-side exhaust header area where temperatures are extreme during performance driving.
3. Direct Injector Problem
All 2022 Camaro engines use direct injection. A factory defect or early carbon deposit on a Bank 2 injector can cause excess fuel delivery. On the V8, check cylinders 2, 4, 6, and 8 for misfire codes alongside P0175.
4. Modification-Related Cause
Aftermarket tunes, intakes, and exhaust modifications are common on the Camaro. A poorly calibrated tune, an intake that changes MAF readings, or headers with exhaust leaks can all trigger P0175. If you recently modified the car, evaluate those changes first.
Diagnosis
- Note all aftermarket modifications
- If tuned, revert to stock and clear codes to test
- Scan for all codes and review freeze frame data
- Monitor Bank 1 vs Bank 2 fuel trims at idle and 3,000+ RPM
- Clean the MAF sensor
- Test Bank 2 O2 sensor with live data
- Check for exhaust leaks at header connections (if aftermarket)
- Perform injector balance test on Bank 2
Costs
MAF cleaning: under $15. O2 sensor: $140-$340. Injector: $200-$600. Tune correction: $200-$500. Exhaust gasket: $100-$350. The 2022 Camaro is under GM's powertrain warranty through 2027, though modifications may affect coverage.
Performance Restoration
The Camaro is built for driving enjoyment, and P0175 compromises that. A rich condition reduces peak horsepower, dulls throttle response, and can cause the ECM to pull timing. Whether you have the turbocharged four-cylinder or the LT4-powered ZL1, fixing P0175 restores the car to its full performance potential. Get it diagnosed and repaired to enjoy the Camaro as intended.
