The P0302 code on your 2022 Toyota Tacoma indicates the engine computer has detected misfires specifically in cylinder 2. The Tacoma's 3.5L 2GR-FKS V6 engine shares architecture with other Toyota V6s, making diagnosis familiar for experienced technicians.
Tacoma V6 Engine Layout
The Tacoma's V6 is mounted longitudinally (front-to-back) unlike the transverse layout in Highlander. Cylinder 2 is on the passenger side bank, positioned in the middle. Access may be slightly different than transverse applications but remains manageable.
Common Misfire Causes
Typical P0302 causes on the 2022 Tacoma include ignition coil failure on cylinder 2, worn or damaged spark plug, fuel injector malfunction, vacuum leak at intake manifold, and rarely, mechanical issues. The coil-on-plug design allows individual cylinder testing.
Truck-Specific Considerations
Tacomas often see varied driving conditions—towing, off-road use, and heavy loads. These conditions can accelerate ignition component wear. If the truck has been worked hard, ignition components may wear faster than a lightly-used vehicle.
Diagnostic Approach
Start with the swap test—move the cylinder 2 coil to another cylinder and see if the misfire follows. This quickly identifies a bad coil. Similarly test the spark plug. Check for any vacuum leaks before assuming internal engine issues.
