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 Pump Module circuit, or a faulty Engine Control Module (ECM).
The importance of repairing this issue lies in the fact that it can lead to increased emissions and decreased fuel efficiency. The repair difficulty is moderate, with a repair time of 1.0 hour. To fix the issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

P2402: Affordable Fix For Your Car’s Evaporative Emission System
The fault code P2402 indicates a problem with the EVAP system. The diagnosis and fixing cost of this fault code depend on the estimated repair time, which is 1.0 hour.
Most auto repair shops charge between $75 and $150 per hour for their services.
Therefore, the total cost of diagnosis and fixing can range from $75 to $150.
Other factors that may influence the cost include the severity of the problem, the type of vehicle, and the location of the repair shop.
P2402: The Lowdown On Evaporative Emission System Leak Detection Pump Control Circuit High
The P2402 code is related to the Evaporative Emission (EVAP) system. It indicates that the leak detection pump is stuck ON. The Engine Control Module (ECM) monitors the EVAP pressure for leaks and actuator malfunctions.
The leak detection pump creates negative pressure in the EVAP system. 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’re experiencing the P2402 fault code, your engine light may be on. This could be due to 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, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for 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 P2402 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.
While a faulty Engine Control Module (ECM) is listed as a possible cause of the P2402 fault code, it is not a common cause. The more common causes include a faulty Canister Pump Module, an open or shorted Canister Pump Module harness, or a poor electrical connection in the Canister Pump Module circuit. To fix the issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
Wrap Up
If your engine light is on and showing the P2402 code, it could be due to a faulty Canister Pump Module, open or shorted harness, poor electrical connection, or a faulty Engine Control Module.
Visually inspect the wiring harness and connectors for damage and check for broken, bent, pushed out, or corroded connector pins.
