MALFUNCTIONING
SYSTEM |
EXPLANATION |
1211 |
DME Control
Unit |
This code is
stored when the DME self test fails. Delete any stored codes. Start
and run the car for 30 seconds. Turn off the ignition for 30
seconds. Rerun the diagnosis. If the same fault recurs, the DME
control unit must be replaced. |
1212 |
Lambda (O2)
Sensor 2 |
This code is
stored when the engine temperature is >70C and the Oxygen Sensor
value is out of range or not present. Check the Oxygen Sensor wiring
and the operation of the sensor. The value should fluctuate between
0.02 and 0.85V. Slow fluctuation indicates a polluted Oxygen sensor
and negative values indicate a damaged sensor. Note: Cars without
Catalytic Convertors will incorrectly store this code. |
1213 |
Lambda Control
2 |
This code is
stored when the DME detects excessive deviations in the air-fuel
mixture (too rich or too lean) for longer than 10 seconds. Possible
causes: Fuel tank ran empty, Incorrect Fuel Pressure, Injector valve
defective or coked, Engine Temperature Sensor defective, Secondary
air leak, Fuel evaporation control system defective, Air Flow
Meter defective and/or the combustion is being disturbed by
mechanical failure (Spark plugs,, compression,
intake/exhaust valves, ...etc.) |
1215 |
Air Mass/Volume
Sensor |
This code is
stored if there is a break or short-circuit at: Air Mass Flow Meter
or its supply wires or the voltage supply to Air Mass Flow Meter
insufficient. Cable damage is the most common cause of this trouble
code. |
1216 |
Throttle
Potentiometer |
This code is
stored if a break or short-circuit occurs in the wiring to the
Throttle Potentiometer or the potentiometer is defective. Damage at
the throttle potentiometer connection is the most common cause of
this fault. |
1218 |
Output Stage,
Group 1 |
This code is
stored if there is a short to B+ or Ground at the Output Amplifier
Stage (Bank 1). Generally this code occurs with other defects.
Causes may be a faulty Idle Speed Actuator, Injector Valves,
Ignition Coil on Plug, Oxygen Sensor Heating Relay, Fuel
Evaporation, Control Valve, Malfunction Indicator Lamp (MIL)
and/or EKP Relay. Delete the code after examining for other faults.
If the code recurs, delete code, then disconnect the DME for a
minimum of 5 minutes to initiate a reset. Rerun car. If code recurs
and no other defects are found the DME is most likely damaged and
must be replaced. If the code does not recur and the engine runs
properly, ignore. |
1219 |

Evaporation, Control Valve, Malfunction Indicator Lamp (MIL)
and/or EKP Relay. Delete the code after examining for other faults.
If the code recurs, delete code, then disconnect the DME for a
minimum of 5 minutes to initiate a reset. Rerun car. If code recurs
and no other defects are found the DME is most likely damaged and
must be replaced. If the code does not recur and the engine runs
properly, ignore. |
1221 |

Sensor 1 |
This code is
stored when the engine temperature is >70C and the Oxygen Sensor
value is out of range or not present. Check the Oxygen Sensor wiring
