Terms

Driving cycle

Starting the engine.

Warming-up cycle

Starting the engine and then an increase in engine temperature of at least 22°C (40°F) to at least 71°C (160°F).

Fault procedure, throttle control

If a safety-related fault should occur in the throttle control, the throttle body will go into mechanical limp-home mode and CHECK ENGINE will immediately go on. The limp-home solenoid is subsequently activated each time the ignition is turned on. The fault will not repair itself and the car must be rectified in a workshop.

When the fault has been rectified, first clear the diagnostic trouble code and then reset the limp-home mechanism.
