Component Testing

Static Test

1. Ignition/Vehicle - Off
2. Disconnect the appropriate electrical connector: Q42 Turbocharger Wastegate Solenoid Valve
3. Test for 15 to 27 ohms between the test points: Ignition terminal 1 & Control terminal 2
   • If not between 15 and 27 ohms 

     Replace the appropriate component: Q42 Turbocharger Wastegate Solenoid Valve

   • Go to next step: If between 15 and 27 ohms 
4. Test for infinite resistance between the test points: Each terminal of the component & The component's housing
   • If less than infinite resistance 

     Replace the appropriate component: Q42 Turbocharger Wastegate Solenoid Valve

   • Go to next step: If infinite resistance 
5. All OK.

Dynamic Test

1. Ignition/Vehicle - Off
2. Disconnect the appropriate electrical connector: Q42 Turbocharger Wastegate Solenoid Valve
3. Connect a jumper wire between the test points: Control terminal 2 & Ground
CAUTION:

Complete the testing as quickly as possible in order to prevent overheating and damaging the component.

5. Momentarily connect a 3 A fused jumper wire between the test points: Control terminal 1 & 12 V

   Verify the component turns On and Off when connecting and disconnecting the jumper wire: Q42 Turbocharger Wastegate Solenoid Valve

   • If the component does not turn On and Off 

     Replace the appropriate component: Q42 Turbocharger Wastegate Solenoid Valve

   • Go to next step: If the component turns On and Off 
6. All OK.
