The trunk module can fail causing the tailgate to malfunction when opening or closing.
The wiring for the transfer case speed sensor can fail causing sporadic operation of the AWD (All Wheel Drive) system.
Rear spring sensor malfunction can cause the rear suspension to sag requiring recalibration of the sensors.
The 2008-2009 SAAB 9-7x and 9-7x Aero use a throttle position sensor (TPS) which commonly fails and causes:
- Check engine light illumination
- Reduced Power message
- OBD trouble code P2135
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.
To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.
Porosity in the rear of the engine block can cause oil leakage around the rear engine cover. Porosity may be found at rear of the engine and the repair procedure in the service bulletin describes using RTV silicone sealant to fill the porosity. There is also an updated rear engine cover for when porosity is found on the gasket mating surface.
Leaks in the air suspension can cause the air compressor to run constantly.
