throttle body connector and control unit connector and check if there is cables 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 3 and 15 is within 1 and 2.5 Ohm; if it is not, replace the throttle body; if it is,
check that the throttle body is not mechanically blocked: if blocked, solve the problem and
replace the body; if it is not, replace the control unit
DIAGNOSIS INSTRUMENT: LOGIC ERRORS
potentiometer 1 sensor, front throttle position P0121
•
signal not valid
Error cause
•
Signal not within the expected value drawn according to the values of the intake pressure
Troubleshooting
•
Check the parameter of the Potentiometer 1 Front throttle (voltage) to get which signal the
control unit receives and to compare it to the Potentiometer 1 Rear throttle (voltage). Check
the throttle body connector as well as the control unit connector. Check that cable resistance
between the throttle body connector (PIN 1) and the control unit (PIN48) is a few tenths of
an Ohm. If this is not the case, restore the cable harness. If the value is correct, replace the
complete throttle body
potentiometer 2 sensor, front throttle position P0123
•
signal not valid
Error cause
•
Signal not within the expected value drawn according to the values of the intake pressure
Troubleshooting
•
Check the parameter of the Potentiometer 2 Front throttle (voltage) to get which signal the
control unit receives and to compare it to the Potentiometer 2 Rear throttle (voltage). Check
the throttle body connector as well as the control unit connector. Check that cable resistance
between the throttle body connector (PIN 4) and the control unit (PIN 50) is a few tenths of
an Ohm. If this is not the case, restore the cable harness. If the value is correct, replace the
complete throttle body
