Idle Mixture Adjuster (IMA) Sensor

The IMA sensor is mounted in control box. This sensor works in conjunction with oxygen sensors to maintain correct air/fuel ratio at idle. Sensor is factory adjusted and sealed to prevent tampering. Turning adjuster changes voltage signal to ECU, which in turn alters fuel discharge duration.
