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 1 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 throttle valve control unit connector. Check that
cable resistance between the throttle body connector (PIN 4) and the throttle control unit
(PIN 5A) 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.
Front throttle valve position sensors P0124
- illogical signal.
Error cause
•
Potentiometer 1 and potentiometer 2 do not show a logical value: the sum of the two voltages
should be constant. The cause may be a malfunction in one of the two sensors or an ab-
normal resistance in one of the two circuits.
Troubleshooting
•
Check the throttle body connector as well as the throttle control unit connector. Check that
cable resistance between the throttle body connector (PIN 1) and the throttle control unit
(PIN 6A) is a few tenths of an Ohm. Check that cable resistance between the throttle body
connector (PIN 4) and the throttle control unit (PIN 5A) is a few tenths of an Ohm. If one of
the two is different, restore the cable harness. If correct, replace the complete throttle body.
Potentiometer 1 sensor, rear throttle position P0126
- 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 Rear throttle (voltage) to get which signal the
control unit receives and to compare it to the Potentiometer 1 Front throttle (voltage). Check
the throttle body connector as well as the throttle control unit connector. Check that cable
resistance between the throttle body connector (PIN 1) and the throttle control unit (PIN 6B)
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, rear throttle position P0128
- signal not valid.
