DOOSAN DTCs - fault codes list
12 Indicates the end of one pass through the fault list.
14 ECT Sensor Input The low level normally appears if the coolant sensor wire is shorted to ground.
15 The ECT sensor input is high if the coolant sensor wire is disconnected or the wire is broken.
16 ECT too high a coolant temperature, measures an excessive temperature or is short-circuited or on the weight sits.
22 Throttle sensor. Input signal line InputLo TPS1 in the break
23 The throttle input sensor TPS1 is shorted
24 Sensor of the throttle valve TPS. Sensor malfunction
25 Throttle valve temperature sensor TPS Sensor malfunction
26 ETC the supply wire of the ETC sensor in the breakage or the throttle plate sticks out inside the throttle body
27 The projected difference in TPS TPS 1 differs from the calculated position
28 ETC early test triggered. Error of return of a spring throttle заслонки
29 ETC Driver Fault Current driver throttle or driver signals shorted
33 Sensor low signal MAP wire in the open or open chip
34 High MAP signal shorted or sensor failure
37 IAT sensor input low, TMP sensor fault or short circuit
38 IAT sensor input high, TMAP disabled or IAT signal open
42 EST 1. Low coil driver signal is low or short-circuited by plus
43 EST 1. High excitation signal of high or high current coil
52 Engine oil pressure too low
53 Input of the battery charge sensor, low battery voltage measured below 8.0 VDC
54 Battery sensor input high battery voltage, measured above 15.9 VDC
55 Sensor input XDRP sensor low, below 4.6V DC
56 Sensor input XDRP high sensor level, above 5.2 VDC
57 Increased engine speed exceeded the set maximum speed setting
61 Pedal sensor input 1 Lo APP1 signal is disconnected, circuit open or sensor malfunction
62 Pedal sensor input 1 Hi sensor error APP1 or short circuit
63 Pedal sensor range 1 Lo potentiometer APP1
64 Range of pedal sensors 1 Hi potentiometer APP1 does not work
65 Pedal sensor sensor input Lo sensor error APP2 or short circuit
66 Pedal sensor input 2 Hi APP2 signal disabled, open circuit or sensor malfunction
67 Pedal sensor range 2 Local potentiometer failure APP2
68 Pedal sensor range 2 Hi APP2 Potentiometer fault
69 Pedal 1. Pedal 2. The difference in the measured pedal position signal APP2 is different from APP1
71 AFR Trim Valve Output. FTV modulation driver signal error
72 Shutoff valve AFR lower duty cycle FTV at lower limit (LEAN)
73 AFR Trim Valve upper duty cycle DC FTV at the upper (RICH) limit
74 Switching the sensor O2 of the sensor does not switch over the reference AFR voltage
77 Oxygen sensor input The high O2 sensor signal is shorted to +5 VDC.
