crank the engine. If the sensors are good, "sen ­
sor okay" will appear on the display. If either

proceed to checking Memory Problem Diagno­
sis Test No.1 and 2.

NOTE: To check if the memory is clear, per­
form "Memory Diagnosis Test 1 and 2" to
see if all sensors test good. If a problem still
remains on either memory, repeat "clearing

Throttle Valve Angle Test (Degrees)
The correct throttle valve angle is extremely impor­
tant for proper engine operation. If the throttle valve
angle isn't correct in the idle position, the engine
may be very difficult to start "cold". If the throttle
valve angle isn't correct in any of the off-idle posi ­
tions, engine damage or poor performance may
result because of an incorrect mixture.
To test the throttle position sensor, use the follow­
ing procedure:
NOTE: The engine should not be running
for the first portion of the throttle valve
test.
