Inspect Crankshaft Position Sensor Resistance

a Disconnect the B22 CKP sensor connector. b Measure the resistance between terminals 1 and 2. Standard resistance Terms cold and hot refer to the temperature of the sensor. Cold means approximately -10 to 50 C 14 to 122 F . Hot means approximately 50 to 100 C 122 to 212 F . c Reconnect the CKP sensor connector.

Toyota Rav4 2000 P0304 Misfire Detected Cylinder

P030x Toyota 4runner

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...
