P2403: Affordable Fix For Your Car’s Evaporative Emission System
The fault code P2403 indicates a problem with the EVAP system.
The diagnosis involves checking the EVAP purge solenoid valve and the wiring. The estimated repair time for this fault code is 1.0 hour.
The cost of fixing this fault code depends on the hourly rate charged by the auto repair shop, which is usually between $75 and $150 per hour. Other factors that may influence the cost include the location of the repair shop, the severity of the problem, and the type of vehicle.
P2403: Fuel Cap Sensor Circuit Low – What It Means?
The P2403 fault code is related to the Evaporative Emission System.
It is caused by a variation in the current consumption of the Leak Detection Pump during the reference phase. The Engine Control Module (ECM) checks the power consumption of the pump and stores a diagnostic trouble code if it varies too much.
This fault code can be diagnosed when the leak diagnostic system is run. The code specifically refers to the Leak Detection Pump Sense CircuitO.
