Details of the Honda p2135 OBD Code
Honda P2135 code indicates a throttle/pedal position sensor/switch A/B voltage correlation issue.
Code P2135 on a Honda indicates a throttle/pedal position sensor/switch A/B voltage correlation issue.
This code is triggered by the Engine Control Module (ECM) when it detects that the voltage signals from the throttle position sensor and the pedal position sensor do not correlate as expected.
This can lead to drivability issues and may put the vehicle in a reduced power mode to prevent further damage.
Mechanic’s Tech Notes
