recently I have been having issues with my 2007 saab 9-7x 5.3 with 130k miles. It started going into limp mode originally every once and a while and got increasing worse. Now after sitting for 2 weeks i went to start it up and it now hunts like crazy and barley runs. It currently reads the following codes:
P0122 TP sensor 1 Low Volt
P0223 TP sensor 2 High Volt
P0526 Fan Speed Sensor (This was present for ~6 months before the limp mode)
P060E Control Module Throttle Position System Circuitry Performance
P0121 TP Sensor Performance
After looking online, unplugging the fan, which I guess can bring the throttle sensor voltage down, made no difference.
I have replaced the Throttle Body, and cleaned the connector, with no change.
Anyone have any experience with this? I cannot drive the car now as it barley idles, but before if I would start it, and let it get hot, it would not go into limp.
Possibly wiring issue? If so I don't have any good wiring schematics.
