Component Testing

Dynamic Test - Using Vehicle Harness

NOTE:

Circuit/System Testing must be performed before proceeding with Component Testing.

1. Ignition/Vehicle - Off
2. Remove the component: B111B Turbocharger Boost/Intake Air Temperature Sensor - Leave the electrical connector connected.
3. Install - EN-23738-A Vacuum Pump @B111B Turbocharger Boost/Intake Air Temperature Sensor
4. Use the tool to achieve a gauge reading between -13 and -21 kPa (-0. 13 and -0. 21 bar, -3. 8 and -6. 2 in Hg).

   Verify the scan tool parameter: Boost Pressure Sensor = Decreases between 13 and 21 kPa (1. 9 and 3. 0 PSI)

   • If the parameter does not decrease between 13 and 21 kPa (1. 9 and 3. 0 PSI) 

     Replace the component: B111B Turbocharger Boost/Intake Air Temperature Sensor

   • Go to next step: If the parameter decreases between 13 and 21 kPa (1. 9 and 3. 0 PSI) 
5. Use the tool to achieve a gauge reading between -30 and -38 kPa (-0. 3 and -0. 38 bar, -8. 8 and -11. 2 in Hg).

   Verify the scan tool parameter: Boost Pressure Sensor = Decreases between 30 and 38 kPa (4. 4 and 5. 5 PSI)

   • If the parameter does not decrease between 30 and 38 kPa (4. 4 and 5. 5 PSI) 

     Replace the component: B111B Turbocharger Boost/Intake Air Temperature Sensor

   • Go to next step: If the parameter decreases between 30 and 38 kPa (4. 4 and 5. 5 PSI) 
6. All OK.

Dynamic Test - Using Jumper Wires

1. Ignition/Vehicle - Off
2. Remove the component: B111B Turbocharger Boost/Intake Air Temperature Sensor
3. Connect a 3 A fused jumper wire between the test points: 5 V Reference terminal 1 & 5 V
4. Connect a jumper wire between the test points: Low Reference terminal 2 & Ground
5. Connect a DMM between the test points: Signal terminal 4@B111B Turbocharger Boost/Intake Air Temperature Sensor & Ground
6. Install - EN-23738-A Vacuum Pump @B111B Turbocharger Boost/Intake Air Temperature Sensor
7. Use the tool to achieve a gauge reading between 0 and -15 kPa (0 and -0. 15 bar, 0 and -4. 4 in Hg).

   Verify the DMM displays between 0. 2 and 4. 9 V. - The value should not spike or drop out.

   • If not between 0. 2 and 4. 9 V or has spikes or drops out 

     Replace the component: B111B Turbocharger Boost/Intake Air Temperature Sensor

   • Go to next step: If between 0. 2 and 4. 9 V and there are no spikes or drops out 
8. All OK.
