Hi my check engine light came on today. I scanned the codes and it reads P2A00 and P1172. I am not sure what they mean, can it be an oxygen sensor? Some help would be nice. Thanks.

Hi Guys, I'm new in this group. I hope somebody can help me. I'm posting this in behalf of my uncle. His 2008 Model CRV recently had a check engine pop-up, and when we scanned it, here was the code. P2A00 1. A/F Sensor B1S1 Circuit Range/Performance Problem 2. A/F Sensor S1 Circuit...

2006 CRV with the P1172 and P2A00 codes being thrown after the CEL came on. This is some sort of oxygen sensor but I'm not sure which one and if more than one. Can anybody shed light on the exact part number(s) I need to replace the sensor(s). Thanks!!
