The P3073 fault code indicates a problem with the engine coolant pump’s current. The engine coolant pump is responsible for maintaining an efficient engine operating temperature.

When the engine is cold, the coolant does not flow to the radiator until the thermostat opens. The DTC will be set when the Engine Coolant Pump Current is not within a calibrated range for greater than 3 seconds.

This fault code indicates that the engine coolant pump is not functioning properly, which can lead to engine overheating and damage.

What are the possible causes of the P3073 automobile fault code?

If you’re experiencing the P3073 fault code, your engine light may be on. This could be due to a faulty engine coolant pump, an open or shorted engine coolant pump harness, a poor electrical connection in the engine coolant pump circuit, or a faulty engine control module. To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can one visually inspect the related wiring harness and connectors to fix the P3073 fault code?

If you’re experiencing the P3073 fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few possible causes. These include a faulty engine coolant pump, an open or shorted engine coolant pump harness, a poor electrical connection in the engine coolant pump circuit, or a faulty engine control module (ECM).
