What Does the P2418 Code Mean?
OBD-II Code P2418 is defined as an Evaporative Emission System Switching Valve Control Circuit/Open. This code indicates a problem with the Leak Detection Pump, which is part of the Evaporative Emissions System (EVAP). When the vehicle is turned off and has been sitting for a while, the engine computer (PCM) attempts to activate the Leak Detection Pump to create a vacuum in the EVAP system. If the PCM fails to detect the activation of the pump or the creation of a vacuum, it triggers the P2418 code.
What Causes the P2418 Code?
Several issues can lead to the P2418 code being set, including:
- Canister pump module failure
- Leaking or restricted EVAP hose
- Powertrain Control Module (PCM) failure
- Wiring issues
What Are the Symptoms of the P2418 Code?
Symptoms associated with the P2418 code may include:
- Check Engine Light illuminated
- Failed emissions test
- Possible fuel odor
- Decreased fuel efficiency
