2023年6月26日 · The P2402 code is a diagnostic trouble code (DTC) that indicates a problem with the evaporative emission system. This system is responsible for capturing and storing fuel vapors that would otherwise be released into the atmosphere.

2024年3月26日 · What causes the P2402 code to appear? Common causes include a faulty leak detection pump, damaged wiring or connectors in the EVAP system, a malfunctioning EVAP control module, or excessive corrosion in the pump assembly.

The P2402 fault code in automobiles indicates a problem with the Canister Pump Module. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this issue could be a faulty Canister Pump Module, an open or shorted Canister Pump Module harness, a poor electrical connection in the Canister ...

2024年9月15日 · A common reason for the P2402 code is a loose or damaged gas cap, which lets fuel vapors escape and messes up the pressure in the EVAP system. Leaking or damaged EVAP hoses also let fuel vapors escape, causing pressure problems that trigger the code.

P2402 is an OBD-II generic code for the engine control module (ECM) detecting the evaporative system leak detection pump control circuit has a high voltage signal return. What causes the P2402 code? The ECM monitors the EVAP control system pump current and if the current goes higher than specified then the code is set.

The P2402 diagnostic trouble code for Toyota vehicles indicates that the Evaporative Emission Leak Detection Pump is stuck ON. This system is part of the vehicle's evaporative emissions control system, which is designed to capture and store fuel vapors from the fuel tank and prevent them from escaping into the atmosphere.

The BMW P2402 code is a diagnostic trouble code that indicates a problem with the evaporative emission system leak detection pump control circuit. This code is considered to be moderately serious, as it can cause issues with the vehicle’s emissions system and potentially lead to decreased fuel efficiency and performance.

2025年2月2日 · When the P2402 code is triggered, it indicates that the electrical circuit controlling this pump is experiencing higher than normal voltage levels. While the P2402 code primarily affects the emissions system, it can manifest in various ways:

What Is the P2402 Code? Can I Still Drive? P2401 and P2402 codes indicate that there’s an issue with your evaporative emissions (EVAP) system. The “Leak Detection Pump” is part of the EVAP...

2024年3月26日 · Code P2402 Description. 5 hours after the ignition switch is turned off, the leak detection pump creates negative pressure (vacuum) in the Evaporative Emission (EVAP) system. The Engine Control Module (ECM) monitors for leaks and actuator malfunctions based on the EVAP pressure.
