The redesigned 2022 Mitsubishi Outlander delivers family SUV capability with the efficient 2.5L four-cylinder engine. When your Outlander displays a P0304 code indicating a cylinder 4 misfire, understanding this modern powertrain helps guide accurate diagnosis.
Understanding P0304 in the Outlander
The 2022 Outlander features a 2.5L naturally aspirated four-cylinder engine on a platform shared with Nissan. Cylinder 4 is located at the rear of the inline-4 engine, nearest the firewall. The engine control module monitors combustion events through crankshaft position analysis.
Redesigned Platform
The 2022 Outlander was completely redesigned, sharing its platform with the Nissan Rogue. The 2.5L engine is known for reliability across Nissan applications. First-year production may have specific technical service bulletins to consider.
Diagnostic Approach
Access the cylinder 4 ignition coil at the engine's rear. Inspect spark plug electrode condition. Check for vacuum leaks in the intake manifold. Verify fuel injector operation if ignition components check out.
Resolution Process
Replace spark plugs with Mitsubishi specifications if worn. Test ignition coil output. Address any vacuum leaks identified during diagnosis.
