Cel p2241/2251 - 05tl 5at
Hi Aziners,
Have 105K kms (~60K miles) on my TL and received my first CEL yesterday. Scan came up with P2241 (Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) IP Line Low Voltage) initially. Since it wasn't running roughly, I cleared it but on a quick run around the block the CEL lit up again. This time it scanned P2251 (Rear Air/Fuel Ratio (A/F) Sensor (Bank 1, Sensor 1) VS Line High Voltage). Cleared it again but haven't gone for another run but expect that it'll probably come back on during my drive to work tomorrow.
Searched the problem/fixes area and will likely replacing O2 sensors (Denso) but would appreciate any feedback on why the change in DTC code. Just concerned that it's something else upstream affecting the O2 sensors.
Have AEM v2 CAI (~1 yr) but doubt that it's contributing to the problem.
Thanks for any feedback.

Update: CEL now reads P0134 - O2 Sensor CAN$277?
CEL came back on and now it reads P0134 consistently -cleared it a couple of times and reads the same. Checked with Dealer and it's $277 and Canadian Tire ($196 - NGK) 
Anyone with resources for better pricing?
TIA.

i wouldn't do aftermarket they tend to fail due to it's design. The oem ones work best with the vehicle. If you compair the sensors side by side (OEM vs Aftermarket) they will diff in design from one another and this my friend will cause the CEL to return pretty quick. You can try www.acuraoemparts.com or try TIM a vendor on this website who sells oem parts.
