P2406: Affordable Fix For Your Car’s Evaporative System
The fault code P2406 indicates a problem with the evaporative emission system. The diagnosis involves checking the fuel tank pressure sensor and the purge valve.
The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue depends on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.
Other factors that may affect the cost include the cost of replacement parts and any additional repairs that may be required.
P2406: Your Car’s Fuel Cap Is Loose!
The P2406 fault code is related to the evaporative emissions control circuit.
It is stored in the engine control module when there is a malfunction with the circuit. The EVAP system allows the fuel tank to be vented in a controlled manner without releasing harmful gas emissions into the atmosphere. The engine control module monitors the circuit integrity by monitoring the inductive spike generated when the solenoid valve is switched off.
The system may not purge the carbon canister under idle conditions.
An actuator test may be used to operate the solenoid valve with a scan tool. Manufacturers have to closely monitor the system due to the presence of harmful hydrocarbons within the system.
The engine control module can monitor the system for leaks and for excessive or insufficient flow.
