The BMW P2402 Code is an indication of a malfunction in the EVAP Leak Detection Pump Control Circuit. This code is triggered when the car’s engine starts, the battery voltage must be at least 11.5v, all electrical components must be off, parking brake must be engaged, the automatic transmission selector must be in park, and the exhaust system must be properly sealed. This code is triggered when the EVAP Leak Detection Pump Control Circuit is malfunctioning, which can be due to a range of causes including an open EVAP LDP power supply circuit, a damaged or failed EVAP LDP solenoid valve, a leak or poor seal in the EVAP LDP canister, an improper seal in the EVAP canister system, or a failure of the Evaporative Emission (EVAP) canister purge regulator valve. In the following table, readers will find the causes and corresponding solutions for the BMW P2402 Code.
Causes & Solutions for BMW P2402 Code
| Cause | Solution |
|---|---|
| EVAP LDP power supply circuit is open | Check the wiring and connectors for any signs of damage, repair or replace any damaged parts as required. |
| EVAP LDP solenoid valve is damaged or has failed | Replace the solenoid valve with a new one. |
| EVAP LDP canister has a leak or a poor seal | Check for any signs of damage and replace the canister if needed. |
| EVAP canister system has an improper seal | Check the seals and replace if needed. |
| Evaporative Emission (EVAP) canister purge regulator valve 1 has | Replace the valve if needed. |
When the BMW P2402 Code is triggered, it is essential to take the necessary steps to diagnose and fix the issue. This code is an indication of a malfunction in the EVAP Leak Detection Pump Control Circuit, which can be caused by a range of different issues. In order to successfully resolve the problem, it is important to identify the cause and take the appropriate actions to repair the issue. By referencing the above table, readers are able to identify the potential causes and solutions for the BMW P2402 Code.
EVAP LDP Power Supply Circuit
If the EVAP LDP power supply circuit is open, it is necessary to check the wiring and connectors for any signs of damage. If any damage is found, it is important to repair or replace any damaged parts as required.
EVAP LDP Solenoid Valve
If the EVAP LDP solenoid valve is damaged or has failed, it is necessary to replace the solenoid valve with a new one. This is essential in order to prevent further issues from occurring.
EVAP LDP Canister
If the EVAP LDP canister has a leak or a poor seal, it is necessary to check for any signs of damage and replace the canister if needed. This should be done in order to ensure the optimal functioning of the EVAP LDP.
EVAP Canister System
If the EVAP canister system has an improper seal, it is necessary to check the seals and replace if needed. This is important in order to prevent further issues from occurring.
Evaporative Emission (EVAP) Canister Purge Regulator Valve
If the Evaporative Emission (EVAP) canister purge regulator valve has failed, it is necessary to replace the valve if needed. This should be done in order to ensure the optimal functioning of the EVAP system.
Conclusion
To conclude, when the BMW P2402 Code is triggered, it is essential to take the necessary steps to diagnose and fix the issue. By using the table above, readers can identify the potential causes and solutions for the BMW P2402 Code. It is important to identify the cause and take the appropriate actions to repair the issue in order to successfully resolve the problem.
