A pump control circuit high can cause emissions issue—scan, test wiring, reprogram or replace. Specifically monitors the electrical control circuit of the leak detection pump (ldp) used to pressurize the evap system 2 specific fault indicates evap leak detection pump control circuit high, signaling that the pcm detected an abnormally high voltage on the pump's control circuit, typically due to a short to power or a faulty pump. 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 leak detection pump is part of the evaporative emissions system After the vehicle has been sitting for a few hours, this pump will turn on and create a vacuum in the evap system The engine computer (pcm) runs this test when the vehicle is off. Replace the leak detection pump if it fails testing or shows internal faults

Repair or replace damaged wiring or connectors in the pump control circuit

Replace blown fuse or faulty relay associated with the evap system Repair open circuits or shorts in the wiring harness. 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

The leak detection pump creates negative pressure through the reference orifice. The p2402 fault code indicates a problem with the control circuit of the evaporative emission system leak detection pump This system is responsible for capturing and recovering fuel vapors from the fuel tank to prevent them from escaping into the atmosphere A high voltage or short circuit condition in the control circuit can trigger this code, leading to potential issues with emissions and.

For many jeep grand cherokee owners, this specific diagnostic trouble code signals a small leak in the evaporative emission control (evap) system

It's a common problem, but one that can lead to failed emissions tests, reduced fuel efficiency, and a general headache. For a reference current measurement the motor pump is switched on for a small period of time while the changeover valve and purge control valves are closed In this mode fresh air is pumped through the 0.02 inch reference orifice and the pump motor current is measured At some unusual operating conditions the pump current may not stabilize

In this case an optional 0.02 or 0.04 inch leak.

Evaporative emission control (evap) system This system captures fuel vapors from the fuel tank and stores them in a charcoal canister, preventing their release into the atmosphere These vapors are later purged and burned in the engine. The vent solenoid allows fresh air into the evap system during the purge cycle and seals the system during leak tests

If it's malfunctioning, it can prevent proper venting or sealing, leading to incorrect pressure readings and thus, an incorrect purge flow detection.
