Details of the Honda p1659 OBD Code
The Honda P1659 fault code relates to the malfunction of the VTCS solenoid valve control circuit.
OBD code P1659 for Honda vehicles indicates an issue with the EVAP purge control solenoid valve circuit.
This code is triggered by the Engine Control Module (ECM) when it detects a malfunction in the electrical circuit of the EVAP purge control solenoid valve.
The EVAP system is responsible for capturing and storing fuel vapors to prevent them from escaping into the atmosphere.
The purge control solenoid valve controls the flow of fuel vapors from the charcoal canister to the engine intake manifold for combustion.
When P1659 is set, it means there is a problem with this valve or its circuit, which can lead to emissions issues and potentially affect engine performance.
Mechanic’s Tech Notes
For Honda code P1659, check for a malfunction in the electronic throttle control system.
