Default RE: CODES!!!!

ORIGINAL: Alero99

car was def warmed up... idk how high cuz i have a 160 tstat and my temp sending unit is not working... but the car ran for about 7 or so minutes before i re did the test
Get rid of that 160° t-stat..... install a 180°F, and keep engine @2000 rpms for 2 minutes after you let it raise temp idling for 5-8 minutes. Code 21 is not necessarily a problem with the sensor, the engine is too cold.
