3 Code

00283，00285，00290，00287 Possible

causes

［Note］When vehicle speed is over 20km/h，code will be set if sensor signal

is not within the gap specification.

［Method］Code may be set for sensor coil or wiring harness intermittent

poor contact or short, weak sensor signal caused by big gap between sensor

and gear ring or defective gear ring teeth..
