Code Definition

P3010 — Fuel pump cooling relay circuit open or shorted to ground

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Audi

About P3010

P3010 is a manufacturer-specific powertrain diagnostic trouble code recorded for Audi vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P3010 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; and a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P3010 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The engine control module (ECM) sets this code when it detects an open circuit or a short to ground in the fuel pump cooling relay circuit. Some vehicles use a fuel pump cooling system to prevent overheating, especially in high-performance or forced induction applications. A fault in this circuit can lead to inadequate cooling, potentially affecting fuel pump efficiency and longevity.
