In the LCD (DISPLAY) panel, the malfunction code is indicated from small code to large code.
*1
To get the proper signal from the throttle position sensor, the sensor basic position is indicated in the LCD
(DISPLAY) panel. The malfunction code is indicated in three digits. In front of the three digits, a line appears
in any of the three positions, upper, middle or lower line. If the indication is upper or lower line when engine
rpm is 1 100 r/min, slightly turn the throttle position sensor and bring the line to the middle.
In the normal condition, the throttle valve stop screw pushes throttle valves slightly, and middle line will be
indicated.
*2
When the secondary throttle valve actuator and secondary throttle position sensor signals are not sent to
ECM. In this case, C28 and C29 are indicated alternately.
