Fault code 5: Elimination:
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.
- Switch off ignition
- Pull plug off the angle sensor for HBA, front
- Switch ignition on
- Read the fault memory and observe whether fault code 5 reappears.
If fault code 5 does not reappear, the supply lead to the angle sensor for HBA, front, is faulty. Proceed as follows in this case:
- Measure voltage between terminal 5 of the sensor plug and ground Voltmeter display approx. 5 V
- Measure voltage between terminal 5 and terminal 1 of the sensor plug
- Voltmeter display approx. 5V
- In the PST2 menu item Actual values, select Sensor voltage, spring travel 1
- Connect a jumper to terminals 4 and 5 of the sensor plug
PST2 display approx. 5 V
If no fault is detected in the wires or control module, replace the angle sensor for HBA, front.
If fault code 5 reappears after the plug has been removed from the angle sensor for HBA, front, there is a fault in the supply lead to the angle sensor for HBA, rear. Proceed as follows in this case:
- Pull plug off the angle sensor for HBA, rear
- Measure voltage between terminal 5 of the sensor plug and ground Voltmeter display approx. 5 V
- Measure voltage between terminal 5 and terminal 1 of the sensor plug
Voltmeter display approx. 5 V
- In the PST2 menu item Actual values, select Sensor voltage, spring travel 2
- Connect a jumper to terminals 4 and 5 of the sensor plug
PST2 display approx. 5 V
If no fault is detected in the wires or control module, replace the angle sensor for HBA, rear.
