Toyota Rav4 2000 P0304 Misfire Detected Cylinder 4
Random Multiple Cylinder Misfire Detected When the engine misfires, high concentrations of hydrocarbons HC enter the exhaust gas. Extremely high HC concentration levels can cause increases in exhaust emission levels. High concentrations of HC can also cause increases in the Three-Way Catalytic Converter TWC temperature, which may cause damage to the TWC. To prevent these increases in emissions and to limit the possibility of thermal damage, the ECM monitors the misfire rate. When the...

In operation D, the canister pressure sensor measures the EVAP system pressure. The pressure measurement for purge VSV monitor is begun when the purge VSV is turned ON open after the EVAP leak check. When the measured pressure indicates an increase of 0.3 kPa-g 2.25 mmHg-g or more, the purge VSV is functioning normally. If the pressure does not increase, the ECM interprets this as the purge VSV being stuck closed. The ECM illuminates the MIL and sets the DTC 2 trip detection logic .
