Understanding P0175 on the 2024 Ford Maverick
The 2024 Ford Maverick displays P0175 when the PCM detects an overly rich fuel mixture. The 2024 model continues with the 2.5L Atkinson-cycle hybrid (191 combined hp) as the base powertrain and the optional 2.0L EcoBoost turbocharged four-cylinder (250 hp). For 2024, the Maverick received a refresh with updated styling and features, but the powertrains remain fundamentally the same as previous model years.
New for 2024
The 2024 Maverick adds the Tremor off-road package and other updates. The Tremor package includes larger tires and suspension changes but does not modify the engine or fuel system. The powertrain calibrations may have minor updates for 2024, which could affect fuel trim thresholds, but the core diagnostic approach for P0175 is unchanged.
Symptoms
- Check engine light on the updated digital instrument cluster
- Fuel economy below the rated 42 MPG city (hybrid) or 23/30 MPG (EcoBoost)
- Engine roughness during running periods
- Dark exhaust emissions
- Fuel smell from tailpipe
- Hybrid may show increased engine-on time
Causes
1. MAF Sensor Contamination
Even at low mileage on a 2024 model, the MAF sensor can accumulate contamination from PCV blow-by during engine break-in and from environmental dust. The Tremor package's off-road use increases dust exposure. Clean the MAF sensor first as it is free and resolves many P0175 codes immediately.
2. O2 Sensor Defect
On a new 2024 vehicle, a failing O2 sensor is a manufacturing defect covered under warranty. The sensor may have been contaminated during assembly or have an internal defect. This is a straightforward warranty replacement.
3. Software Calibration
As a relatively new model with updates for 2024, Ford may release PCM calibration updates through TSBs. A software issue that affects fuel trim calculations can trigger P0175 without any hardware fault. Check with the dealer for available updates.
4. Injector or Boost System Issue
On the EcoBoost, a direct injector defect or boost system fitment issue from the factory can cause rich running. On the hybrid, a port injector defect or EVAP system issue is possible. Both are warranty items on a 2024 model.
Recommended Action
- Take the 2024 Maverick to the Ford dealer for warranty diagnosis
- Ask about TSBs related to P0175 for the 2024 model year
- If you want a quick check first, clean the MAF sensor
- Document all symptoms for the dealer visit
- Do not attempt major repairs on a new warranty vehicle
Costs
Under warranty: free. If diagnosing independently: MAF cleaning under $15, O2 sensor $150-$350, PCM reflash $100-$200, injector $120-$650 depending on engine. Take advantage of full warranty coverage on the 2024 model.
Priority
Schedule a dealer appointment within a week. Running rich on a new engine during break-in can cause oil dilution, which is particularly concerning during the critical first 10,000 miles. The repair is free under warranty, so there is no reason to delay.
