3. Method of Trouble Shooting

Failure Code:

P0105-1

Over-high intake manifold absolute pressure sensor signal

Set emergency control scheme:  Switch on the failure lamp till the failure disappears

 When the engine stops: 90 kPa
 When the engine idles: = 45 kPa
 When the engine operates: the pressure of manifold changes

as the opening of throttle

 If the cylinder pressure detection technology is applied,

there is 50% of probability that the fuel injection sequence

has 360 degree of ram off.
