P240B OBD-II: Evaporative Emission System Leak Detection Pump Heater Control
P240B Severity
Will P240B go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P240B?
The DTML Pump pressurizes the fuel tank to check for leaks when the vehicle is off. If this pump fails, code P240A will be set.
