Defect Code 44

Defect code 44:

•D• 900 Defect code memory: 44 Intake air temperature sensor:

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 or 50° C at 3.5 I with M1.3.

Troubleshooting: As displayed on screen. For temperature sensor test values, refer to - Component Testing -.
