•
Short-circuit to positive: disconnect the coil connector, turn the key to ON, activate the coil
with the diagnostic tool and check the voltage at PIN 2 of the connector: if there is voltage,
restore the wiring harness, if the voltage is 0, replace the coil.
•
If open circuit, short circuit to negative: check the electrical characteristics of the coil: if not
ok, replace the coil; if ok, perform the check procedure for the coil connector and for the
Marelli control unit connector; if not ok restore; if everything is ok, check the continuity of the
cable between the two ends of the cable: if there is no continuity, restore the wiring harness;
if there is continuity, with key ON, check the cable ground insulation (from the coil connector
or control unit connector); if not ok, restore the wiring harness.
P0354 Coil 4
Electrical diagnosis:
•
Short circuit to positive / short circuit to negative, open circuit.
Error cause:
•
Short-circuit to positive: an excessive voltage was detected at PIN 1 of the ENGINE con-
nector. If open circuit, short circuit to negative: a voltage equal to zero was detected at PIN
1 of the ENGINE connector.
Troubleshooting:
•
Short-circuit to positive: disconnect the coil connector, turn the key to ON, activate the coil
with the diagnostic tool and check the voltage at PIN 1 of the connector: if there is voltage,
restore the wiring harness, if the voltage is 0, replace the coil.
•
If open circuit, short circuit to negative: check the electrical characteristics of the coil: if not
ok, replace the coil; if ok, perform the check procedure for the coil connector and for the
Marelli control unit connector; if not ok restore; if everything is ok, check the continuity of the
cable between the two ends of the cable: if there is no continuity, restore the wiring harness;
if there is continuity, with key ON, check the cable ground insulation (from the coil connector
or control unit connector); if not ok, restore the wiring harness.
Throttle body
Function
Sends to the injection control unit the throttle position and activates the throttle according to the control
unit
Operation / Operating principle
All the unit internal components (potentiometer and electric motor) are contactless; therefore, no elec-
trical diagnosis is possible for the throttle body, but for the circuits connected to it only.
