Diagnostic tool - Electrical errors
Left injector P0201 - shorted to positive / shorted to negative / open circuit.
Error cause
•
Short-circuit to positive: excessive voltage at PIN 34 of the control unit connector
•
Short-circuit to negative: zero voltage at PIN 1 of the left injector connector
•
Open circuit: circuit interruption
Troubleshooting
Short-circuit to positive:
•
Disconnect the left injector connector, turn the key to ON and activate the component
through the diagnostic tool.
•
Verify the absence of voltage at the left injector connector PIN 2; if present restore the wiring
harness, otherwise proceed with the following checks.
Short-circuit to negative:
•
Disconnect the left injector connector, turn the key to ON and activate the component
through the diagnostic tool.
•
Verify the presence of voltage at the ends of the left injector connector; if there is no voltage,
restore the wiring harness, otherwise proceed with the following checks.
Open circuit:
•
Carry out the check procedure of the left injector and control unit connectors.
•
Verify continuity of the wiring harness between the control unit connector and the left injector
connector (control unit PIN 34 - left injector PIN 2). In the absence of continuity restore the
wiring harness.
