Hallo Isialex,
hier die Codes:
1 ...oxy sensor open circuit.
2 airflow sensor out of operating range
3 coolant temp sensor out of operating range
4 oxy sensor indicates full rich
5 throttle potentiometer/airflow sensor...
(low throttle pot signal with high airflow sensor signal)
6 throttle pot/airflow sensor......
(high throttle pot signal with low airflow sensor signal)
7 throttle pot...idle fuel adjustment failure(idle speed??)
8 intake air temp sensor...open or shorted circuit to sensor
11 Throttle pot at idle: Throttle pot idle trim out of normal range
12 Airflow meter: MAF signal out of range
14 Coolant thermistor: Resistance out of range or static during Engine warm up
16 Air thermistor: Resistance out of range
17 Throttle pot: Out of range
18 Throttle pot/Airflow: Low throttle pot signal at high airflow
19 Throttle pot/Airflow: High throttle pot signal at low airflow
22 Fuel pump drive: ECU output to fuel pump relay
23 Fuel supply: Engine running too rich
24 Ignition Drive: ECU output to ignition Amp
26 Air leak: Engine running too lean
29 ECU self check
33 Injector Drive: ECU output to injectors
34 Injector: Looks for Injector dribble
37 EGR Drive: ECU output to EGR switching valve
39 EGR check sensor: EGR not working (normally pipe blocked)
44 Lambda (O2) sensor: Poor mixture control rich or weak (or misfire)
46 Idle speed Control valve: ECU output to Coil AB
47 Idle speed Control valve: ECU output to Coil CD
48 Idle Speed Control Valve: Stepper motor grossly out of position
66 Air pump: ECU output to air pump relay
68 Road speed sensor: Seen speed < 5km/h at high engine airflow
69 Drive/Neutral switch: Seen cranking in "D" or high airflow in "N"
89 Purge Valve drive: ECU output to purge valve
For UK and Middle East cars; Codes 11,12,14,16,17,18.19 and 68 will illuminate warning light. This will remain on until engine is switched off.
Catalyst (non-Federal) and Australian spec cars; Same as UK but codes 23,26 and 44 will light the warning lamp.
Federal Spec Vehicles (i.e. USA); All codes illuminate warning lamp
