Checking the throttle body
The throttle bodies are maintenance free and are
not serviceable. Replace the entire assembly in
the event of malfunction.
As all the internal components of the throttle body
assembly (potentiometers and electrical motor)
are contactless, no electrical diagnosis is possible.
Functional tests are performed on the throttle body
assembly by the control unit during vehicle oper-
ation, with the results visible on the diagnostic
instrument.
The only action possible before replacing the com-
ponent is checking the connectors and cable har-
nesses.
Installing the throttle body
•
When installing the throttle body, refer
to the electrical system section for the
correct cable routing.
•
Ensure that the injector connectors are
correctly fastened.
•
Connect the control unit connector, en-
suring that the security lock is in the
locked position.
