CHECKING ENGINE DURING IDLE
The engine control unit is designed to adjust the torque
issued by the engine during idle.
Set up the connection between the control unit and the
diagnostic software. With the engine warm and the fans
on, in idle, in neutral, observing the following parame-
ters through the diagnostic software within the recom-
mended intervals, you are able to control the operation
of the correct motor.
RIVALE 800:
Engine rpm
Adaptive lambda check
Suction pressure
Engine load
Throttle capacity adaptability min -1%
Operation outside of the recommended intervals is a
sign that the engine is not running correctly.
If the recommended intervals are not being main-
tained, it is a good idea to proceed with the following
checks in order to find the cause that is making the
engine operate outside of the intervals provided above:
- checking, with a diagnosis, the validated system
errors;
- checking the petrol pressure and making sure the
injectors are working;
- making sure the throttle body is working correctly;
- making sure the exhaust is working correctly (correct
installation, holes, leaks, the state of the catalyst,
etc);
- checking engine phase.
