The P2403 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 the 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 P2403 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, Evaporative Emission (EVAP) system fault, Fuel cap warning light ON, Fuel smell from the vehicle, Decreased fuel economy, Rough engine idle, Engine stalling or hesitation during acceleration, Failed emission test, and Reduced engine performance.
  • If you notice any of these symptoms, it is important to get your vehicle checked by a professional mechanic to avoid further damage.

The automobile fault code P2403 can be caused by a range of issues, including a faulty leak detection pump and a clogged charcoal canister.

  • The automobile fault code P2403 can be caused by a faulty Leak Detection Pump.
  • It can also be caused by an open or shorted Leak Detection Pump harness.
  • Poor electrical connection in the Leak Detection Pump circuit can also trigger this fault code.
  • Another cause is a faulty Purge Valve.
  • Lastly, a clogged or damaged charcoal canister can also be the reason for the P2403 fault code.

To fix the p2403 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2403, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.

The fault code P2403 indicates a problem with the EVAP system.

The diagnosis involves checking the EVAP purge solenoid valve and the wiring. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this fault code depends on the hourly rate charged by the auto repair shop, which is usually between $75 and $150 per hour. Other factors that may influence the cost include the location of the repair shop, the severity of the problem, and the type of vehicle.

The P2403 fault code is related to the Evaporative Emission System.

It is caused by a variation in the current consumption of the Leak Detection Pump during the reference phase. The Engine Control Module (ECM) checks the power consumption of the pump and stores a diagnostic trouble code if it varies too much.

This fault code can be diagnosed when the leak diagnostic system is run. The code specifically refers to the Leak Detection Pump Sense CircuitO.

What are the possible causes of the automobile fault code P2403?

If you see the engine light on or the service engine soon warning light, it could be due to the P2403 fault code. This code is usually caused by a faulty leak detection pump, an open or shorted leak detection pump harness, a poor electrical connection in the leak detection pump circuit, 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 damaged components or broken, bent, pushed out, or corroded connector’s pins.
