: Just 3 months ago, I had the error code 1264..and it was due to a bad O2 sensor. Replaced it. Now it's bad again !? Code 1221 is specifically the O2. I'll measure it tomorrow to make sure.

: Any ideas why this would happen ?

: Thanks for any incite/experience,

Check your crank sensor, I got error 1222 (O2 Sensor) but it was actually a dirty crank sensor. Look on my website under tech to see how to fix the sensor. This may be the problem. Good luck.
