Static Test
- Ignition/Vehicle - Off
- Disconnect the electrical connector: Q42 Turbocharger Wastegate Solenoid Valve
- Test for 20 to 26 ohms between the test points: Control terminal 2 & 12 V Reference terminal 1
- If not between 20 and 26 ohms
Replace the component:Q42 Turbocharger Wastegate Solenoid Valve
- Go to next step: If between 20 and 26 ohms
- If not between 20 and 26 ohms
- Test for infinite resistance between the test points: Each terminal of the component & The component's housing
- If less than infinite resistance
Replace the component: Q42 Turbocharger Wastegate Solenoid Valve
- Go to next step: If infinite resistance
- If less than infinite resistance
- All OK.
Dynamic Test
- Ignition/Vehicle - Off
- Disconnect the electrical connector: Q42 Turbocharger Wastegate Solenoid Valve
- Connect a 10 A fused jumper wire between the test points: 12 V Reference terminal 1 & 12 V
- Momentarily connect a jumper wire between the test points:Control terminal 1 & Ground
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 component: Q42 Turbocharger Wastegate Solenoid Valve
- Go to next step: If the component turns On and Off
- If the component does not turn On and Off
- All OK.
CAUTION:
