DESTRUCTIVE COMBUSTION MISFIRE
State ET014 : Recognition of the cylinder 1 must be active, in order to
identify each cylinder.
ET093 : combustion misfire on cylinder 1
ET094 : combustion misfire on cylinder 2
ET095 : combustion misfire on cylinder 3
ET096 : combustion misfire on cylinder 4
These will provide information regarding failure cause and location.
In this situation, the problem is probably due to an element that can act
only on one cylinder:
- Problem at injector
A cylinder is declared
- Problem at spark plug
damaged
: ET093
or
ET094 - Problem at high voltage cable.
or ET095 or ET096. Before replacement, try the spark plug or cable changing to another
cylinder.
Cylinders 1 and 4 or In this cylinders 2 and 3 declared situation, the problem is probably
damaged : ET093 and ET096 due to an element that can act only this pair of cylinders:
or ET094 and ET095. - Problem at ignition coil, at the high voltage part.
- Problem at ignition coil, at the control part
In this situation, the problem is probably due to an element that can
Four cylinders declared act only on all cylinders:
damaged
: ET093
and -
Problem at fuel filter
ET094
or
ET095 and ET096.
-
Problem at fuel pump
- Problem on in use fuel type
-
Problem of in use spark plugs
In case by using this method the problem is not solved, consult the failures diagnostic DF109 / DF
110 CONTINUA TION
Ensure that all failures are solved. Erase all memorized failures.
There is no need to erase the “adaptive values” memorized by the injection computer.
In order to check the correct reparation of the system, the following conditions must be
AFTER
accomplished:
REPARATION
- No more electrical failures;
- All “adaptive values” to be memorized by the injection computer;
- Warm engine (minimum 75°C);
- Run at idling, all consumers being in use for 20 minutes (1 minute DF110);
- If the failure is again occurring, repeat the diagnostic.
