(4) Trouble diagnosis: By monitoring the throttle-alternator position, when the signal higher or
lower than its limit, the ECU will confirm that the throttle position sensor is in trouble, then the
engine operation under trouble mode will be applied, and the engine MIL will be lighted (Knock on
sensor and internal dirt will contribute to engine troubles.)
(5) Installation: Fastening torque for installation screw is 1.5N·m～2.5N·m.
