No_under analysis_standby_Yes
DIAGNOSIS INSTRUMENT: ELECTRICAL ERRORS
CAUTION
IF THE ELECTRIC CIRCUIT IS INTERRUPTED OR SHORT-CIRCUITED, NO ERROR IS DIS-
PLAYED. CHECK THE ENGINE SPEED SENSOR CONNECTOR AND THE MARELLI CONTROL
UNIT CONNECTOR: IF NOT OK, RESTORE; IF OK, CHECK THE CORRECT ELECTRIC CHAR-
ACTERISTICS OF THE SENSOR: IF NOT OK, REPLACE THE SENSOR. IF OK, CHECK THAT
THERE IS CONTINUITY ON BOTH CABLES, SUPPLY INSULATION AND GROUND INSULATION.
CARRY OUT THE TESTS FROM THE SENSOR CONNECTOR TO THE SENSOR. IF NOT OK, RE-
STORE THE CABLE HARNESS/REPLACE THE SENSOR. IF OK, PERFORM THE TEST FROM PIN
20 AND 35 OF THE MARELLI CONTROL UNIT ENGINE CONNECTOR.
DIAGNOSIS INSTRUMENT: LOGIC ERRORS
Engine speed sensor P0336
•
signal not valid
Error cause
•
Probable bad contact in the electric circuit detected at PIN 20 - 35 of the ENGINE connector
Troubleshooting
•
Check the electric circuit is in good conditions and the flywheel teeth cleaning and correct
positioning of the sensor in its own housing: if it is not, replace it. If it is OK, replace the
sensor
