P1149
P1149
Diagnosis information - Control unit DME (DFI)
Oil pressure control valve: Power supply
Diagnostic conditions
- Engine running
Possible fault causes
- Open circuit/short circuit to ground (Power supply Oil pressure control valve)
- Short circuit to B+/ground or open circuit in the line (Activation Oil pressure control valve)
- Oil pressure control valve Faulty
P1150
P1150
Diagnosis information - Control unit DME (DFI)
Oil pressure control valve: Activation
INFORMATION
- The oil pressure-regulating valve is controlled via a PWM signal.
- The PWM signal depends, among other things, on the ambient conditions (temperatures, off time, etc), operating point of the engine (rpm,
load, oil temperature), measured oil pressure (at the oil pressure sensor)...
- A fault is detected if the PWM signal is outside a defined range for > 8 seconds.
Diagnostic conditions
- Engine running
Possible fault causes
- Short circuit to B+ (Activation Oil pressure control valve)
- Open circuit/short circuit to B+ (Power supply Oil pressure control valve)
- Oil pressure control valve Faulty
P1151
P1151
Diagnosis information - Control unit DME (DFI)
Oil pressure control valve: Activation
INFORMATION
- The oil pressure-regulating valve is controlled via a PWM signal.
- The PWM signal depends, among other things, on the ambient conditions (temperatures, off time, etc), operating point of the engine (rpm,
load, oil temperature), measured oil pressure (at the oil pressure sensor)..
- A fault is detected if the PWM signal is outside a defined range for > 8 seconds.
- The oil pressure is reduced to the minimum pressure in the event of a short circuit to ground.
