• Causes
• Solutions

The P2510 fault code indicates a problem with the ECM/PCM Power Relay Sense Circuit, specifically relating to its range or performance. This circuit is critical for ensuring that the engine control module (ECM) or powertrain control module (PCM) receives the proper voltage levels from the power relay. If the voltage is outside of expected parameters, it can lead to erratic performance or failure of the engine management system.

What are the symptoms of the P2510 code?

Symptoms associated with a P2510 code may consist of:

• Warning lights on the dashboard, including the check engine light.
• Rough idling or stalling of the engine.
• Poor fuel economy as the system fails to operate optimally.
• Difficulty starting the vehicle, or intermittent starting issues.
• Overall poor performance of the engine due to compromised control module functionality.

What causes the P2510 code?

Common causes of the P2510 code include:

• A faulty ECM or PCM.
• Damage to the wiring or connectors in the power relay sense circuit.
• A defective power relay that is not supplying adequate power.
• A blown fuse that impacts the operation of the ECM/PCM.
• Poor ground connection affecting the circuit's performance.

How to fix P2510?

To resolve a P2510 fault code, consider the following steps:

• Inspect the power relay and replace it if faulty.
• Check all related wiring and connectors for damage or corrosion, and repair as needed.
• Test the ECM/PCM for proper functionality and replace if necessary.
• Ensure all fuses related to the engine management system are intact and replace any that are blown.
• Clean and secure any ground connections associated with the power relay circuit.
