Condition for fault identification

Test condition:

The fault is recognized when the voltage values for the two throttle valve sensors are not within the valid range for the emergency-air position while an activation signal is not being applied (Sensor 1: 0.74 V +/- 0.3 V; Sensor 2: 4.26 V +/- 0.3 V)

Potential problem source(s):

• Throttle valve operation impaired by contamination
• Defective throttle valve

  Terminal condition: Terminal 15

  Voltage condition:

• Electrical system voltage > 10 V

  Temperature condition:

• Intake air temperature > -10 °C
• Coolant temperature > -10 °C
• Coolant temperature < 142 °C

  Time condition:

• 5 sec.

  Other conditions:

• Engine off
• No other throttle valve diagnostic fault codes logged in control module fault memory
