Explanation: This defect code is stored when shorts or breaks occur at the temperature sensor or on its supply wires. A prerequisite for detecting a break in the circuit is a 3 min interval after the start and the engine idling for a minimum of 30 sec. After the defect code is set, the system operates with a substitute value of 20° C.
