ATF temperature sensor [Transmission Fluid Temperature Sensor 'A' Circuit Low/High/Range/Performance]
Note. The ignition must be switched off and then switched on again in order to display a fault indication in the instrument cluster. Use the 'Actual values' menu in the Porsche System Tester II No. 9588 to check the transmission status and the actual values of
the shift solenoid valves and sensors.
Oil pressure switch 1, transmission [Transmission Fluid Pressure Sensor/Switch 'A' Circuit]
Note. The ignition must be switched off and then switched on again in order to display an error message in the instrument cluster.
Note. This fault indicates that the solenoid/control valves in the hydraulic pressure circuit of 'oil pressure switch 1' keep jamming/sticking, or that 'transmission oil pressure switch 1' keeps jamming/sticking!
Use the 'Actual values' menu in the Porsche System Tester II No. 9588 to check the transmission status and the actual values of the shift solenoid valves and sensors.
Oil pressure switch 1, transmission [Transmission Fluid Pressure Sensor/Switch 'A' Circuit Range/Performance]
Note. The ignition must be switched off and then switched on again in order to display an error message in the instrument cluster.
Use the 'Actual values' menu in the 9588 Porsche System Tester II to check the transmission status and the actual values of the shift solenoid valves and sensors.
Oil pressure switch 2, transmission [Transmission Fluid Pressure Sensor/Switch 'B' Circuit]
Note. The ignition must be switched off and then switched on again in order to display an error message in the instrument cluster.
Use the 'Actual values' menu in the Porsche System Tester II No. 9588 to check the transmission status and the actual values of the shift solenoid valves and sensors.
Note. This fault indicates that the solenoid/control valves in the hydraulic pressure circuit of 'oil pressure switch 2' keep jamming/sticking, or that 'transmission oil pressure switch 2' keeps jamming/sticking!
System in limp-home mode 1: Fault not caused by incorrect gear ratio or unusual switching!
Note. Please refer to ' LIMP-HOME MODE 1 ' table in the main chapter entitled 'Control module function (coding/programming)'!
Oil pressure switch 2, transmission [Transmission Fluid Pressure Sensor/Switch 'B' Circuit Range/Performance]
Note. The ignition must be switched off and then switched on again in order to display an error message in the instrument cluster.
Use the 'Actual values' menu in the Porsche System Tester II No. 9588 to check the transmission status and the actual values of the shift solenoid valves and sensors.
