•
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 control unit connector. Check that resist-
ance of cable between throttle body connector (PIN 1) and control unit (PIN 48) is a few
tenths of an Ohm. Check that resistance of the cable between throttle body connector (PIN
4) and the control unit (PIN 50) is a few tenths of an Ohm. If one of both is different, restore
cable harness, if OK, replace the entire throttle body

•
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 control unit connector. Check that the resistance
of the cable between the throttle body connector (PIN 1) and the control unit (PIN 36) is a
few tenths of an Ohm. If different, restore cable harness, if OK, replace the entire throttle
body
potentiometer 2 sensor, front throttle position P0128
•
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 rear throttle (voltage) to get which signal the
control unit receives and to compare it to the Potentiometer 2 front throttle (voltage). Check
the throttle body connector as well as the control unit connector. Check that the resistance
of the cable between the throttle body connector (PIN 4) and the throttle control unit (PIN
21) is a few tenths of an Ohm. If different, restore cable harness, if OK, replace the entire
throttle body
