The P0302 code indicates your 2022 Toyota RAV4's engine computer has detected a misfire condition in cylinder 2. The RAV4's 2.5L Dynamic Force 4-cylinder engine uses advanced technologies that require systematic diagnosis to identify the misfire source.
Understanding RAV4 Misfire Detection
The 2022 RAV4's ECM uses crankshaft position data to monitor each cylinder's contribution to engine rotation. When cylinder 2 doesn't produce expected power, the ECM logs P0302. The high-compression (13:1) Dynamic Force engine is sensitive to ignition and fuel delivery issues.
Common P0302 Causes
Typical causes in the 2022 RAV4 include faulty ignition coil on cylinder 2, spark plug issues (gap, wear, or damage), direct fuel injector malfunction or clogging, intake valve carbon deposits affecting airflow, and less commonly, vacuum leaks or mechanical issues.
Diagnostic Strategy
Start with the most common and accessible causes. Inspect and test the cylinder 2 ignition coil by swapping with another cylinder. Examine the spark plug for proper gap (0.043 inch) and condition. Check injector operation with diagnostic equipment. The direct injection system may have spray pattern issues even if electrically functional.
Direct Injection Considerations
The RAV4's D-4S dual injection system uses both port and direct injection. Carbon buildup on intake valves can occur since direct injection doesn't wash the valves. If other components check out, consider intake valve inspection and cleaning.
