I have a 2008 Chevy Equinox and I had an O2 Sensor code run so we changed the O2 sensor and then had more codes pop up which ended up resulting in getting a new catalytic converter. Now I have the P0030 code and P0134 codes running which are due to the Heater Control Circuit in Bank 1 Sensor 1 which is the brand new one that I just put in. I also recently had codes P0700, P0716, P0717 (transmission control module requested MIL illumination, Input/turbine speed sensor circuit Range/performance, turbine speed sensor circuit no signal) pop up and before I start to purchase a bunch of random parts to fix these problems, I'm wondering if anyone has seen these codes run together. If you have were they two different issues or were they caused by one thing. My cruise control does still work along with my reverse gear. It does take long to get going after sitting at a stop light in town or dropping down to 10mph and then it also tops out at 60mph with 4000rpms.

 

Hello, Melodee Strauch, Welcome to the Chevrolet Forums.

IIRC, sometimes a repair will tend to cause some false codes to be thrown. If you disconnect the battery for about ten minutes, this should clear the
old codes. Then, respond to the new codes, as they show up.
