Common Fault Code Cases and Analysis
Case 1: Fault Code 0091-08 - Throttle Position Signal Abnormality
Main Fault Phenomenon: Diesel engine speed must be set using the backup throttle switch.
Cause of Fault: ECM detects that the throttle signal frequency is greater than 2000Hz or less than 150Hz for 2 seconds.
System Reaction: ECM will record the fault code (0091-08), which can be viewed on the display module or ET. The ECM will mark the throttle position as invalid data and will maintain the recent diesel engine speed until: a. ECM receives a different diesel engine speed signal from the backup throttle switch; b. The signal from the throttle switch becomes valid and remains so for more than 2 seconds.
Case 2: Fault Code 0094-03 - Fuel Pressure Sensor Circuit Open/Short to Battery Positive
Main Fault Phenomenon: Diesel engine stops or does not run.
Cause of Fault: ECM detects all of the following: a. ECM reads a signal voltage higher than 4.8V for 8 seconds; b. Power has been supplied to the ECM for at least 2 seconds; c. Fault code 0262-03 (5V sensor supply line shorted to battery positive) is not currently present; d. Fault code 0262-04 (5V sensor supply line shorted to ground) is not currently present; e. The diesel engine is not running, or the diesel engine has been running for at least 3 minutes.
System Reaction: ECM will record the fault code (0094-03), which can be viewed on the display module or ET. The ECM will mark the fuel pressure as invalid data and use a default value of 600kPa. If you need to replace the fuel pressure sensor, Growshine International offers high-quality aftermarket options with part number variations suitable for your Doosan excavator.
Case 3: Fault Code 0094-04 - Fuel Pressure Sensor Short to Ground
Main Fault Phenomenon: Diesel engine stops or does not run.
Cause of Fault: ECM detects all of the following: a. ECM reads a signal voltage higher than 4.8V for 8 seconds; b. Power has been supplied to the ECM for at least 2 seconds; c. Fault code 0262-03 (5V sensor supply line shorted to battery positive) is not currently present; d. Fault code 0262-04 (5V sensor supply line shorted to ground) is not currently present; e. The diesel engine is not running, or the diesel engine has been running for at least 3 minutes.
System Reaction: ECM will record the fault code (0094-04), which can be viewed on the display module or ET. The ECM will mark the fuel pressure as invalid data and use a default value of 600kPa. Ensure your Doosan 280-3 or Doosan 280-5 has the correct fuel pressure sensor for optimal performance.
Case 4: Fault Code 0100-03 - Engine Oil Pressure Sensor Circuit Open/Short to Battery Positive
Main Fault Phenomenon: a. Diesel engine operates at low power; b. Diesel engine speed decreases.
Cause of Fault: ECM detects all of the following: a. ECM reads a signal voltage higher than 4.8V for 8 seconds; b. Power has been supplied to the ECM for at least 2 seconds; c. Fault code 0262-03 (5V sensor supply line shorted to battery positive) is not currently present; d. Fault code 0262-04 (5V sensor supply line shorted to ground) is not currently present; e. The diesel engine is not running.
System Reaction: ECM will record the fault code (0100-03), which can be viewed on the display module or ET. The ECM will mark the engine oil pressure as invalid data and use a default value of 600kPa. Proper engine oil pressure is crucial for the longevity of your Doosan excavator's engine.
Case 5: Fault Code 0100-04 - Engine Oil Pressure Sensor Short to Ground
Main Fault Phenomenon: a. Diesel engine operates at low power; b. Diesel engine speed decreases.
Cause of Fault: ECM detects all of the following: a. ECM reads a signal voltage lower than 0.2V for 18 seconds; b. Power has been supplied to the ECM for at least 2 seconds; c. Fault code 0262-03 (5V sensor supply line shorted to battery positive) is not currently present; d. Fault code 0262-04 (5V sensor supply line shorted to ground) is not currently present; e. The diesel engine is not running.
System Reaction: ECM will record the fault code (0100-04), which can be viewed on the display module or ET. The ECM will mark the engine oil pressure as invalid data and use a default value of 600kPa. Growshine International offers a wide range of engine oil pressure sensors compatible with your Doosan 280-5.
Case 6: Fault Code 0110-03 - Coolant Temperature Sensor Circuit Open/Short to Battery Positive
Main Fault Phenomenon: a. Diesel engine will not enter cold mode; b. Diesel engine will not start; c. Diesel engine operates at low power; d. Diesel engine speed decreases.
Cause of Fault: ECM detects all of the following: a. ECM reads a signal voltage higher than 4.92V for 8 seconds; b. Power has been supplied to the ECM for at least 2 seconds.
System Reaction: ECM will record the fault code (0110-03), which can be viewed on the display module or ET. The ECM will mark the coolant temperature as invalid data and use a default value of 90°C.
Case 7: Fault Code 0110-04 - Coolant Temperature Sensor Short to Ground
Main Fault Phenomenon: a. Diesel engine will not start; b. Diesel engine operates at low power; c. Diesel engine speed decreases.
Cause of Fault: ECM detects all of the following: a. ECM reads a signal voltage lower than 0.2V for 8 seconds; b. Power has been supplied to the ECM for at least 2 seconds.
System Reaction: ECM will record the fault code (0110-04), which can be viewed on the display module or ET. The ECM will mark the coolant temperature as invalid data and use a default value of 90°C. When this fault code is current, the diesel engine will not enter cold mode. Ensure your Doosan excavator has a functioning coolant temperature sensor for optimal engine performance.
