Electrical system
NECESSARY, IF THEY ARE OK CHECK THE SENSOR CONFORMS TO THE ELECTRICAL SPEC-
IFICATIONS: IF NECESSARY, REPLACE THE SENSOR, IF IT IS OK, CHECK THE CONTINUITY
ON THE TWO CABLES, VERIFYING THAT THEY ISOLATED FROM THE POWER SUPPLY AND
EARTH. CARRY OUT THE TESTS ON THE CONNECTOR OF THE SENSOR TOWARDS THE SEN-
SOR, IF IT IS NOT OK REPAIR THE WIRING/REPLACE THE SENSOR, IF IT IS OK, CARRY OUT
THE TEST ON PINS 20 TO 35 OF THE MARELLI CONTROL UNIT ENGINE CONNECTOR.
DIAGNOSTIC TOOL: LOGIC ERRORS
P0336 Engine rpm sensor

•
Signal not plausible
Error causes:
•
Potential false contact in the electrical circuit detected at PIN 20 - 35 of the marelli control
unit ENGINE connector
This error is indicated by lighting up in a fixed manner the general warning light.
Troubleshooting:
•
