So I went to the local Autozone and checked the codes with their OBDII and 1. I got this Bank 1 02 sensor #2 P0141 Heater circuit malfunction. 2. Gear ratio incorrect P0730. 3. Imput turbine speed sensor circuit malfunction p0715.

Can someone tell me how to fix these errors. I think I know how to fix the o2 sensor. I just need to know where its at. Btw. I have not been able to fix my transmission problem. I turn the car on and I drive it for like 2 minutes and then it does not want accelerate anymore the rpms go up. I turn it off and then it works fine. It does this all the time now. Can someone please tell me where the solenoids are at and if I can clean them out.
Thanks.
Marc
