Idle Mixture Adjuster Sensor (IMA Sensor)

1. On Accord SEi models, open control box No. 1 and remove rivets securing IMA sensor. Disconnect IMA sensor 3-pole connector. Measure resistance between Brown and Green terminals as shown in Fig 1 while turning adjustment screw.
2. On CRX Si models, measure resistance between Green and Yellow terminals as shown in Fig 1 of control box coupler. On all models, specified resistance value is 0.25-6.2 k/ohms. Replace sensor if resistance is out of range.
