Question

P0063 on 2006 Chrysler Town & Country 3.3L with new ECM

Answer 1

If you replaced a ECM and still get the code P0063, you need to check the harness that lead to this 02 sensor, or better yet measure voltage at the harness You should have battery voltage on the heater control wire, with key on engine off, with the code cleared.
