A P0420 diagnostic code on your 2024 Toyota Tacoma indicates that the catalytic converter efficiency has dropped below acceptable thresholds. The completely redesigned 2024 Tacoma features new turbocharged engines.
2024 Tacoma Engine Options
- 2.4L Turbo 4-cylinder: 228 hp (base engine)
- 2.4L Turbo 4-cylinder i-FORCE MAX Hybrid: 326 hp combined
Both engines use 4-cylinder single-bank configurations.
P0420 on a New Vehicle
A 2024 Tacoma showing P0420 is unusual since converters rarely fail this early:
- O2 Sensor Issues: More likely than converter failure
- Exhaust Problems: Manufacturing defects possible
- Software Calibration: New platform may need updates
