    Codes P0122 and P1122...

    I have a 98 SLS and my check engine light came on, for codes P0122 and P1122. Also the RPMs kinda randomly rev.
    I replaced the throttle position sensor and it was fine for a month or so, then it all came back. any ideas?

    TPS codes.......For your car is there a TPS learn procedure......or have you checked the wiring harness for severe kinks or chafed insulation ?

    TPS learn procedure? Not that I know of, my factory service manual didn't say anything like that...
    I did look for bad wiring at the sensor and at the PCM, but I didn't pull the rest of the harness apart, I kinda doubt there would be any problem inside the conduit
