2008 Equinox with check engine light and code P0404

Recommended Posts

hey guys I have a 2008 chevy equinox that the check engine light will come on from time to time. In addition to the check traction control service stabilink messages keep showing up.


Based off what I've read before I've replaced the EGR valve on it but the messages and lights still appear, but the lights aside the car seems to be missing or rev's up in the 3,000 RPM's at around 20 MPH for a few seconds then finally performs as expected.


A friend has a cheap computer scanner an was able to find the car has one code and it's a P0404 code.


With the EGR valve just being replaced last week is there anything else I can do?

A generic code reader will only do so much, go to Advance Auto and have the codes read again. Sounds like a trans control issue...
