Fast Idle Valve (Accord & Prelude)

WARNING: This page is about a different car, the 1993 Honda Prelude, 1993 Honda Civic del Sol, 1993 Honda Civic, and 1993 Honda Accord. However, it is still accessible from the selected car via links, so may be relevant.
  1. Start engine. Remove fast idle valve cover. Fast idle valve is located near throttle body. See Figure or Figure . Place finger on valve seat area. Check for airflow with engine cold and idling. If airflow does not exist, replace fast idle valve.
  2. Warm engine to full operating temperature (cooling fan comes on). Verify valve is completely closed. Valve is leaking if suction can be felt in valve seat area. Replace valve if valve operation is not as specified.
