Can't reset CEL/MIL light with code reader
I have a 04 4.7 and I changed the upstream passenger O2 sensor after getting a code 0152. My reader no longer detects any codes but the Check engine light still is illuminated. I tried disconnecting the battery but no luck. Any Ideas? Thanks

Your reader needs to turn off the MIL. Disconnecting the battery won't do it.
