P0435

DTC P0435, sometimes indicated as P043500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing catalyst temperature sensor circuit malfunction (bank 2, sensor 1).

The catalytic converter temperature sensor measures the temperature of the exhaust gas flowing through the converter. If the sensor malfunctions, the Check Engine Light will come on. The most common cause of this problem is a failed sensor. If the sensor is not the problem, the wiring or connector may be at fault.
