DME 7.8 DME 7.8 0 0-PFUEB02TFault overview of 911 Turbo (996) and GT 2 as of model year '02 Note! ♦Please note: This fault code overview only applies to the 911 (996) Turbo and GT2 as of model year 2002. ♦For the Turbo up to and including model year 2001, there are separate fault code tables, which differ in some respects from this table. Some fault codes have been renamed in order to implement the changed standards of the Californian environmen- tal agency. ♦The model year allocation refers to the program and data status in the DME control module. • To be certain that a fault is no longer present after a repair or clearing of the fault memory, a short test or test drive should be carried out. This is the only way of ensuring that all diagnosis routines of the DME control module have been performed. • In the case of Tiptronic faults, the fault memory of the Tiptronic must also be read out for diagnosis/troubleshooting. • After a repair, the fault memory must always be cleared. Fault type Signal implausible/implausible operating range/mal- 1: function Fault type Open circuit/no signal 2: Fault type Ground short/below lower limit/lean limit 3: Fault type Short circuit to B+ /above upper limit/rich limit 4: *: In the case of misfire faults, the fault types have a different meaning. Fault type 1: Emission-related fault after starting Fault type 3: Emission-related fault during journey Fault type 4: Fault damaging to catalytic converter **: In the case of oxygen sensor faults, the fault types have a different meaning. Fault type 1: All electrical faults (open circuit, short circuit to B+ or ground) cause this fault output Fault type 2: Interference from the oxygen sensor heater in the sensor signal Fault type 3: Oxygen sensor aging fault, sensor dynamic response Fault type 4: Oxygen sensor aging fault, sensor contamination and shift of characteristic Fault overview of 911 Turbo (996) and GT 2 as of model year '02 ... 0-PFUEB02T page 1 Printed in Germany – 14, 2003 fue_02t
