P2401: Affordable Fix For Your Car’s Evaporative Emission System
The fault code P2401 indicates a problem with the evaporative emission system. The most common causes of this code are a faulty fuel cap, a leak in the fuel tank or fuel lines, or a malfunctioning purge valve. The estimated repair time for this code is 1.0 hour, and the cost of fixing it can range from $75 to $150 per hour depending on the auto repair shop.
Other factors that may affect the cost include the severity of the problem, the type of vehicle, and the location of the repair shop.
P2401: The Lowdown On Evaporative Emission System Leak Detection Pump Control Circuit/Open
The P2401 code is related to the Evaporative Emission (EVAP) system. It indicates that the Leak Detection Pump is stuck OFF.
The Engine Control Module (ECM) monitors the EVAP pressure for leaks and actuator malfunctions. The leak detection pump creates negative pressure through the reference orifice.
If the EVAP pressure is not between 97 to 100 kPa(abs) within a minute, the ECM interprets this as a malfunction. The ECM illuminates the MIL and stores a Diagnostic Trouble Code (DTC) if this malfunction is detected in consecutive drive cycles.
The Canister Pump Module contains the Canister Pressure Sensor, the Leak Detection Pump, and the Vent Valve.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P2401 fault code. This code is usually caused by a faulty canister pump module, an open or shorted canister pump module harness, a poor electrical connection in the canister pump module circuit, or a faulty engine control module (ECM). 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.
If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2401 fault code, there are a few possible causes to consider. These include a faulty Canister Pump Module, an open or shorted Canister Pump Module harness, a poor electrical connection in the Canister Pump Module circuit, or a faulty Engine Control Module (ECM). To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
