tor); if ground insulated, check that at PIN 2of the throttle boy connector there is power supply
(+5 V) and that at PIN 6 there is ground; if they are correct, replace the throttle body.
P2119 Front throttle valve command circuit
Electrical diagnosis:
•
Short circuit to positive / short circuit to negative / open circuit, excessive internal tempera-
ture over-current.
Error cause:
•
Short-circuit to positive: excessive voltage detected on PIN 29 or 41 of the 7SM control unit.
If short circuit to negative: no voltage has been detected. If open circuit: an interruption of
an excessive Ampere consumption or control unit overheating was detected.
Troubleshooting:
•
Short-circuit to positive: disconnect the throttle body connector, turn the key OK and check
the voltage at PIN 3: if a voltage greater than or equal to 5 V is read, there is a short circuit
of the relative cable, if the voltage is zero, replace the throttle body
•
If short circuit to negative: disconnect the throttle body connector, turn the key ON and check
if PIN 3 has continuity with the vehicle ground: if there is continuity restore the wiring harness,
if there is no continuity replace the throttle body
•
If open circuit, excessive internal temperature over-current: check the throttle body connec-
tor and the control unit connector: if not ok restore, if everything is ok disconnect the
connector of the throttle body and the control unit connector and check cable continuity; if
there is no continuity, restore the cable harness. If there is continuity, with the throttle body
connector connected, check that the resistance, from the throttle control unit connector,
between PIN 29 and 41 is within 1 and 2.5 Ohm; if not ok replace the throttle body, if ok
check that the throttle body is not mechanically blocked: if blocked, remove the cause or
replace the body; if not blocked, replace the control unit.
DIAGNOSTIC TOOL: LOGIC ERRORS
P0121 Front throttle valve position potentiometer 1 sensor
Electrical diagnosis:
•
Signal not plausible.
Error cause:
•
Signal outside the specified value determined based on the values of the intake pressure.
Troubleshooting:
•
Check the parameter of the Potentiometer 1 front throttle valve (voltage) to know which
signal the control unit receives and to compare it to the Potentiometer 1 rear throttle valve
(voltage). Check the throttle body connector and the control unit connector. Check that cable
resistance between the throttle body connector (PIN 1) and the control unit (PIN48) is a few
