What does P2404 mean?

OBD-II Code P2404 is defined as a Evaporative Emission System Leak Detection Pump Sense Circuit. The Evaporative Emission System (EVAP) vents fuel vapors from the tank to the intake manifold so the vapors are burned through the engine’s normal combustion process.

What causes incorrect purge flow?

The main cause is a faulty purge valve. Other common causes include a disconnected or clogged purge line, circuit issues like loose connections or damaged wires, or problems with the control module. Other problems with the EVAP system could also cause issues with the purge flow.

How does leak detection pump work?

It pumps air into the EVAP system to develop a pressure of about 7.5′ H20(1/4) psi. A reed switch in the LDP allows the PCM to monitor the position of the LDP diaphragm. The PCM uses the reed switch input to monitor how fast the LDP is pumping air into the EVAP system. This allows detection of leaks and blockage.

What repairs can fix the P2402 code?

  1. Replace the evaporative pump and fuse.
  2. Replace the evaporative pump relay.
  3. Repair the evaporative pump connector pins for corrosion, melted, or loose connections.
