[SOLVED] P2407 Code: Fixing Evaporative Emission System Leak Detection Pump

The P2407 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.

  • The P2407 fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, issues with the evaporative emission control system, problems with the fuel tank pressure sensor, fuel leaks, decreased fuel efficiency, and difficulty starting the engine.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code P2407 can be caused by a range of issues, including a faulty leak detection pump and a clogged charcoal canister.

  • The automobile fault code P2407 can be caused by a faulty Leak Detection Pump.
  • It can also be caused by an open or shorted Leak Detection Pump harness.
  • Another cause can be a poor electrical connection in the Leak Detection Pump circuit.
  • A faulty Purge Valve can also trigger this fault code.
  • Lastly, a clogged or damaged charcoal canister can also be a cause of the P2407 fault code.

To fix the p2407 automobile fault code, check the possible causes and inspect the related wiring harness, connectors, and components for damage.

  • To fix the automobile fault code P2407, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • Ensure that everything is in good condition.
  • The estimated repair time for this fix is 1.0 hour.

The fault code P2407 indicates a problem with the evaporative emission system. The most common causes of this code are a faulty fuel cap, a leak in the fuel tank or fuel lines, or a malfunctioning purge valve.

The estimated repair time for this code is 1.0 hour, and the cost of fixing it can range from $75 to $150 per hour depending on the auto repair shop. Other factors that may affect the cost include the severity of the problem, the type of vehicle, and the location of the repair shop.

The P2407 fault code is related to the Evaporative Emission System.

The Engine Control Module (ECM) monitors the power consumption of the Leak Detection Pump. If the current consumption of the pump varies too much during the reference phase, a diagnostic trouble code is stored. The P2407 code indicates an intermittent or erratic signal in the Leak Detection Pump sense circuit.

To diagnose this fault code, the leak diagnostic system needs to be run.

What are the possible causes of the automobile fault code P2407?

If you see the engine light on or the service engine soon warning light, it could be due to the P2407 fault code. This code is usually caused by a faulty leak detection pump, an open or shorted harness, poor electrical connection, a faulty purge valve, or a clogged or damaged charcoal canister. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2407 fault code?

If you’re experiencing the P2407 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few possible causes to consider. These include a faulty leak detection pump, an open or shorted pump harness, poor electrical connection in the pump circuit, a faulty purge valve, or a clogged or damaged charcoal canister. To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the steps to take if I find broken, bent, pushed out, or corroded connector’s pins while fixing the P2407 fault code?

If you find broken, bent, pushed out, or corroded connector’s pins while fixing the P2407 fault code, follow these steps. First, disconnect the battery to avoid any electrical shock. Then, carefully inspect the wiring harness and connectors related to the Leak Detection Pump and Purge Valve. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. If you find any, replace or repair them as necessary. Finally, reconnect the battery and clear the fault code to see if the issue has been resolved.

p2407 error fault code explained

If your engine light is on and you have a P2407 fault code, it could be due to a faulty leak detection pump, open or shorted harness, poor electrical connection, faulty purge valve, or cloggeddamaged charcoal canister. Visually inspect the wiring harness and connectors for damage and check for broken, bent, pushed out, or corroded pins.
