Possible Causes of the Issue
Several users on Panswork shared their experiences and suggested potential causes for error code 157-2. Here are the most common possibilities:
- Sensor Issues
Some users indicated that error code 157-2 is often related to engine sensors, particularly the temperature or pressure sensors. If these sensors fail to read or transmit data correctly, it may cause the system to misinterpret information, triggering the error code.
- Electrical Connection Problems
Other users pointed out that electrical connection issues could be the cause of the error. Loose or damaged electrical connections might prevent the correct transmission of sensor data, resulting in the generation of the error code. Ensuring all related electrical connections are secure and undamaged is a crucial step in troubleshooting this issue.
- Engine Control Unit (ECU) Problems
Some users suspected that the issue might lie with the Engine Control Unit (ECU). If the ECU malfunctions, it could misinterpret sensor data, triggering error code 157-2. Checking the ECU for software or hardware issues is a key part of diagnosing this problem.
- Low Voltage or Battery Issues
In certain cases, low voltage or a weak battery might also lead to the appearance of this error code. If the battery voltage is insufficient, the system may fail to start properly, triggering the error. Ensuring that the battery voltage is adequate to power the machine and sensors is an important troubleshooting step.

Solutions
Based on the discussions on Panswork, here are some potential solutions to address the error code 157-2 on the CAT 299D3 skid steer:
- Check the Sensors
Start by inspecting all engine-related sensors, particularly the temperature and pressure sensors. If any sensors are found to be faulty or inaccurate, replace or repair them promptly. Ensuring that the sensors are transmitting data correctly to the ECU is a critical step in resolving this issue.
- Check Electrical Connections
Inspect all electrical connections, ensuring that cables are securely attached and free from corrosion. If any electrical connections are found to be loose or damaged, repair or replace them as necessary. Maintaining the integrity of the electrical system is key to preventing future errors.
- Check the ECU
Examine the Engine Control Unit (ECU) to ensure it is functioning properly. If the ECU is found to be faulty, consider reprogramming or updating its software. Sometimes, a software issue within the ECU can cause the error code to appear, and reprogramming the ECU might resolve the issue. If hardware issues are found, the ECU may need to be replaced.
- Check the Battery and Voltage
Check the battery voltage to ensure it is sufficient to start the machine. If the battery is weak or the voltage is low, replace the battery or recharge it. Ensuring the battery is at the proper voltage is vital for machine startup and sensor operation.
