Engine speed sensor
Function description:
Engine speed sensor is mainly used to
measure engine‟s revolving speed. We can
use it to compare with engine‟s revolving
speed of Camshaft signal sensor. By this
way, engine working will improve stability
and reliability.
Technical parameters:
Normal

temperature:
measuring terminal: -40
℃~
150

Electronic throttle
Function description:
Electronic throttle is mainly used for
controlling mixture flow, engine idling and
maximum revolving speed. ECU controls the
action of throttle and its working stroke is
limited to 10
%~
90
%
(opening of butterfly
valve ) by ECU.
Failure of electronic throttle or bad contact of
connectors will lead to: unstable revolving
speed, unable to start, inhibited acceleration,
unable to acceleration and other failures.
Use multi-meter to check contact status of
connectors; in case that connectors and
wiring harness have no problems, and its
feedback signal bounces, replacement of
new parts shall be taken into consideration.
