P1152
P1152
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
- Open circuit (Activation Oil pressure control valve)
- Open circuit/short circuit to ground (Power supply Oil pressure control valve)
- Oil pressure control valve Faulty
