DIFFERENCE BETWEEN REFERENCE PRESSURE AND OIL
PRESSURE
NOTESThere must be no present or stored faults.
The reference pressure values are stored in the transmission computer memory and depend on how the vehicle
is used.
The oil pressure is regulated according to the reference pressure. The oil pressure values must always be close
to the reference pressure.
This parameter is the difference between parameter PR138 Reference pressure and parameter PR003 Oil
pressure.
–engine not running: reference pressure reading 21 bar.
oil pressure reading = 0 bar.
–engine at idle speed (~ 700 rpm) and selector lever at D or R: reference pressure reading ~ 2.7 bar.
oil pressure reading = ~ 2.6 bar.
–engine speed ~ 1400 rpm and selector lever at D or R: reference pressure reading ~ 8.9 bar.
oil pressure reading = ~ 8.7 bar.
AFTER REPAIRRepeat the conformity check from the start.
