Lancer Cedia – Warning light on and engine rpm is restricted

Replace the APS with a countermeasure

Description of defect

In the accelerator position sensor (APS) of the prime mover, grease was mistakenly applied when the sensor was assembled, and during the process of use, part of the components of this grease formed silicon dioxide on the resistive film surface, resulting in abnormal contact resistance of the sliding parts. The warning light will illuminate and the engine rotation will be restricted.

Improvement details

Replace the APS with a countermeasure.
