    Default Help With Diagnostic Code P219A...

    ran my code reader on my 2010 chevy silverado with 5.3 v8 and the code P219A showed up. All the searches i have ran tell me nothing. Does anybody know what this is? I thought it was an O2 sensor but i lost my diagram of which code goes to which sensor. Thanks!
