The P2405 automobile fault code indicates a problem with the Leak Detection Pump (LDP) or its related components. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty LDP, an open or shorted LDP harness, poor electrical connection in the LDP circuit, a faulty Purge Valve, or a clogged or damaged charcoal canister.

The importance of repairing this issue lies in the fact that it can lead to increased emissions and decreased fuel efficiency.

The repair difficulty is moderate, with a repair time of 1.0 hour. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
