Reconnect CN6, CN7
connectors.
Is throttle motor out of
step?
Remove throttle motor
connector, measure
resistances between B and
Br, B and R, B and O, B
and Y. (Are they within
range of 3.0~3.6 ?)
Remove throttle motor
connector. Is it continuous
between W and L on
throttle motor side?
Remove CNI and measure
resistances between male
side terminals R and B, R
and G, R and W, R and Y..
(Are they within range of
3.0~3.6 ?)
Remove CNI. Is it
continuous between
male side terminal GL
and LgR?
Does throttle motor
operate with
redundancy?
