Code P3073 Cadillac Description
The P3073 Cadillac code indicates that there is low current detected in the engine coolant pump. The engine coolant pump is responsible for circulating coolant through the engine to regulate its temperature. When the current flowing through the coolant pump is lower than expected, it can lead to inadequate coolant circulation, which can result in the engine running too hot. This can cause overheating, reduced engine performance, and potential damage to engine components.
Common Causes of P3073 Cadillac
- Faulty engine coolant pump
- Wiring issues in the coolant pump circuit
- Malfunctioning coolant temperature sensor
- Problem with the engine control module (ECM)
- Low coolant levels
Symptoms of P3073 Cadillac
- Engine overheating
- Reduced engine performance
- Illuminated check engine light
- Coolant leaks
- Engine running hotter than normal
How to Fix P3073 Cadillac
- Diagnose the issue by using a scan tool to read the code and check the coolant pump circuit for any faults.
- Inspect the engine coolant pump for proper operation and replace it if necessary.
- Check the wiring in the coolant pump circuit for any damage or loose connections and repair as needed.
- Test the coolant temperature sensor and replace it if it is malfunctioning.
- If the issue persists, inspect the engine control module (ECM) for any faults and replace if necessary.
Cost to Fix P3073 Cadillac
