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.
The wiring for the transfer case speed sensor can fail causing sporadic operation of the AWD (All Wheel Drive) system.
The trunk module can fail causing the tailgate to malfunction when opening or closing.
Oil can leak from the oil pressure sensor causing a loss of pressure at the sensor and illumination of the oil light.
If a groaning noise is heard from the rear of the vehicle while making turns, the limited slip differential should be inspected. Components should be inspected and replaced as needed.
Rear spring sensor malfunction can cause the rear suspension to sag requiring recalibration of the sensors.
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.
The right/front seat belt retractor assembly can fail causing illumination of the SRS warning light.
The fuel level sender can malfunction causing the fuel gauge to always read at the full level.
Leaks in the air suspension can cause the air compressor to run constantly.
The Vehicle Communications Interface Module can fail causing On-Star to not function properly.
