Throttle Body Test
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2005 Honda S2000, 2004 Honda S2000, 2003 Honda S2000, 2002 Honda S2000, and 2001 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not adjust the throttle stop screw. It is preset at the factory.
- With the engine off, check the throttle cable operation. The cable should operate without binding or sticking.
- If the cable operates OK, go to step 2.
- If the cable binds or sticks, check it and its routing. If it's faulty, reroute it or replace it and adjust it (see THROTTLE CABLE ADJUSTMENT ), then go to step 2.
- Operate the throttle lever by hand to see if the throttle valve and/or shaft are too loose or too tight.
- If there is excessive play in the throttle valve shaft, or any binding in the throttle valve at the fully closed position, replace the throttle body.
- If the throttle valve and shaft are OK, go to step 3.
- Check for clearance (A) between the throttle stop screw (B) and the throttle lever (C) at the fully closed position. If there is any clearance, replace the throttle body (see THROTTLE BODY REMOVAL/INSTALLATION ). Do not adjust the throttle stop screw.
