Doosan Fault Codes list

MALFUNCTION ID / MALFUNCTION DESCRIPTION

12

 Indicates the end of a single fault list pass.

14

 ECT sensor input low level usually appears if the coolant sensor wire is shorted to ground.

15

 ECT sensor input high if coolant sensor wire is disconnected or wire break.

16

 ECT too high coolant temperature, measures excessive temperature or shorted or sits on ground.

22

 Throttle Sensor. Input signal wire InputLo TPS1 open

23

 TPS1 throttle input sensor shorted

24

 TPS throttle sensor sensor. Sensor malfunction

25

 TPS throttle temperature sensor Sensor malfunction

26

 ETC ETC sensor supply wire open or throttle plate protrudes inside the throttle body

27

 Predicted difference TPS TPS 1 differs from design position

28

 ETC early test worked. Throttle spring return error

29

 ETC Driver Fault Current driver throttle or driver signals shorted

33

 Sensors low signal MAP wire in open or open chip

34

 High MAP signal shorted or sensor failure

37

 IAT sensor input low, TMAP sensor failure or short circuit
