PROCEDURE:
●Throttle valve body assembly
Remove the O-ring ⑴ from the intake oipe assembly.
Remove the connection pipe⑾ at the A-end.
Use 10# sleeve to remove the bolt ⑺,take off the External intake air pressure sensor component,injector holder
⑹and injector ⑸.
After loosening the clamp ⑶, remove the throttle valve body assembly ⑷and intake manifold assembly⑵ , and
then remove the clamp ⑶.
●External intake air pressure sensor
Use screwdriver for cruciform head to remove the bolt ⑻,take off the sensor⑼and bracket⑽,then remove the
connection pipe⑾.
●Check whether the temperature sensor is damaged
Remove the temperature sensor from the air filter and place it in the ambient temperature (20 ~ 30 ℃), and use
a multimeter to check whether the resistance of the two pins is between 2726 ~ 1770 Ω.
●Check whether the stepping motor② is damaged
After turning off the power, take out the stepping motor, do not loosen the cable plug, press the flameout switch
at startup without ignition, check whether the motor plug can shrink back and forth, and finally turn off the
flameout switch to check whether the plug returns to its original position.
●Check whether the throttle position sensor ③ is damaged
Connect the diagnostic instrument to the whole vehicle, press the flameout switch (without ignition), turn the
