Causes and Solutions for Nissan Code P2420
| Cause | Solution |
|---|---|
| Canister Pump Module (0.02-inch orifice, vacuum pump, vent valve) | Check for faulty wiring, connections, and possible blockage of the vacuum pump. |
| Connector/Wire Harness (canister pump module – hybrid vehicle control ECU) | Replace the damaged or defective connector/wire harness. |
| Hybrid Vehicle Control ECU | Replace the hybrid vehicle control ECU if it is faulty. |
| Atmospheric pressure, Battery voltage, Vehicle speed, Power switch | Check the atmospheric pressure, battery voltage, vehicle speed, and power switch to ensure they are within the required parameters. |
Canister Pump Module
The Canister Pump Module is one of the common causes of Nissan Code P2420. It includes a 0.02-inch orifice vacuum pump and a vent valve. If the Canister Pump Module is defective, it can lead to several issues with the engine, emission, and fuel systems. To diagnose and troubleshoot the problem, the technician must check the wiring, connections, and the vacuum pump for any blockage.

Connector/Wire Harness
The connector/wire harness, which connects the Canister Pump Module to the Hybrid Vehicle Control ECU, can also cause Nissan Code P2420. The technician must check the connector and wire harness for any damage or defect and replace it if necessary.
Hybrid Vehicle Control ECU
In some cases, the issue may be with the Hybrid Vehicle Control ECU, which controls the evaporative emissions system. If the ECU is faulty, the technician needs to replace it to solve the issue.
Atmospheric Pressure, Battery Voltage, Vehicle Speed, and Power Switch
The atmospheric pressure, battery voltage, vehicle speed, and power switch must be within the required parameters for the evaporative emissions system to function correctly. If the parameters are not within the specified range, the technician must check and adjust the components to get them within the required field.
Conclusion
In conclusion, Nissan Code P2420 indicates a problem with the Evaporative Emission System Switching Valve Control Circuit. It can cause various issues with the engine, emission, and fuel systems. To diagnose and solve this issue, the technician needs to check the Canister Pump Module, Connector/Wire Harness, Hybrid Vehicle Control ECU, and the Atmospheric Pressure, Battery Voltage, Vehicle Speed, and Power Switch. Replacing defective components, such as the Canister Pump Module or Hybrid Vehicle Control ECU, is the best way to resolve the Nissan Code P2420.
