ENGINE CONTROL SYSTEM - ELECTRONIC THROTTLE 11-17

3. Check electronic throttle
(a). Turn ignition switch off, disconnect battery negative cable.
(b). Disconnect electronic throttle connector.
(c). Remove intake tube assembly.
(d). Remove fixed bolt of electronic throttle, and take electronic throttle down.

(e). Turn digital multimeter to ohms range,
connect two probes to No.2 and No.3 pin,
respectively, its resistance value at normal
4 5 6 temperature is 1.25kΩ±30%. 11
1 2 3
(f). Use digital multimeter to detect the
resistance between No.2 pin of electronic
throttle body and No.5/6 pin, and the
resistance between No.3 pin and No.5/6
pin. Stir valve by hand, the resistance shall
have slow linear change; if it's the opposite
condition, the change of two resistance will
be the opposite.
fuwx11005 NOTICE:
If the resistance is outside the scope of the
standard, or the resistance changes unsteadily,
the electronic throttle body assembly shall be
replaced.
4. Install electronic throttle
(a). Install electronic throttle to intake manifold.
(b). Install and tighten the fixed bolt of electronic throttle.
Torque: 10N•m
(c). Connect intake tube assembly, connect electronic throttle connector.
(d). Connect the battery negative.
