A P0302 code on your 2022 Toyota Tundra signals that the engine control module detected misfires in cylinder 2. The 2022 Tundra introduced the all-new twin-turbo V6 engine, representing a significant change from the previous 5.7L V8.
New iForce MAX Powertrain
The 2022 Tundra features either the 3.5L twin-turbo V6 (iForce) or the hybrid version (iForce MAX). This new engine generation has different characteristics than the previous V8. Cylinder 2 is on the passenger bank of this V6 configuration.
Potential P0302 Causes
On the new twin-turbo engine, cylinder 2 misfire causes may include ignition coil failure, spark plug issues (turbo engines are sensitive to plug condition), fuel injector problems, boost-related issues affecting combustion, or manufacturing defects on newer production vehicles.
Turbo Engine Considerations
Turbocharged engines operate under higher cylinder pressures and temperatures. This makes them more sensitive to ignition system condition. Spark plug degradation, even if minor, can cause misfires under boost that wouldn't occur on naturally aspirated engines.
Warranty Coverage
The 2022 Tundra remains under Toyota's warranty. Engine misfire issues should be covered under the basic or powertrain warranty. Document symptoms and have a Toyota dealer diagnose and repair the issue.
