Here's an article about sensors. I wrote it about the Acura Vigor, but all Honda/Acura engines use the same PGM-FI engine management system.

Yours will probably have different wire colors than the ones described in the article. Vigors use YEL/GRN for (+) and GRN/WHT for (-). I believe yours may use RED/WHT for (+) and GRN/BLK for (-) in this circuit. But check to be sure.
