Hello, many vehicles have two oxygen sensors: an upstream oxygen sensor and a downstream oxygen sensor. Make sure you replaced the correct sensor. If so, then you may have a deeper problem causing the issue, possibly the catalytic converter. If you post the code(s) you are getting here, we may be able to help you troubleshoot.
