140101 - P0301

Fault text
Combustion misfiring, cylinder 1: Injection is switched off

Fault description
The diagnostic function monitors the duration of the
combustion strokes and compares them with the remaining
cylinders by assessing the rpm signals (segment periods).

Condition for fault identification
Test condition:
The fault is recognized when the combustion stroke in a
particular cylinder is slower than the combustion strokes on
the other cylinders.
Potential problem source(s):
- Defect in mixture formation
- Defect in ignition system
- Mechanical defect
- Defective DME
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- Engine ON

Condition for fault memory entry
The diagnostic fault code is logged when within 200 :
(KFKSWF) crankshaft revolutions a specified number of
ignition miss events is detected.

Action in service
- Because this is a secondary fault, start by repairing the
primary faults

Fault effect and breakdown warning
Breakdown notice:
The engine reverts to its limp-home program, continued
vehicle operation is possible but drivability is restricted,
because power is reduced the driver should refrain from
passing maneuvers.
Possible apparent symptoms:
- Reduced engine power
