programming
value- 12% < PR090 < 12%
PR090, an adaptive built-in action, is
a stored parameter designed to
program variation and engine ageing
for the idle speed regulator. These
are programmed only when the
engine is idling and warm, and no
electrical consumers (electrical
windscreen, air conditioning, GMV,
power steering) have been selected.
Therefore it adjusts slowly.

throttlePR091: Theoretical

regulation
OCR0% < PR091 < 100%
When the conditions for regulation
are met, the idle regulator continually
repositions the motorised throttle to
keep the engine speed at the idling
speed setting. The motorised throttle
opening ratio required to adhere to
the engine speed setpoint is then
given by parameter PR091.
