Codes P0134, P2243, P2237, and P2251
I pulled Codes P0134, P2243, P2237, and P2251, all bank 1 sensor 1. I bought a sensor, 36531-RCA-A02. I believe I need to change the sensor near the firewall, on the passenger side. Do these codes indicate anything else that needs changing?

P0134 Oxygen Sensor Circuit No Activity Detected Bank 1 Sensor 1
P2243 Oxygen Sensor Reference Voltage Circuit/Open Bank 1 Sensor 1
P2237 Oxygen Sensor Positive Current Control Circuit/Open Bank 1 Sensor 1P2251 Oxygen Sensor Negative Current Control Circuit/Open Bank 1 Sensor 1
I'd certainly start with an O2 sensor change, firewall side upper sensor.

Thank you for the reply. I bought a OBD 2 scan tool last week, worth every penny ($94+tax). The codes are exactly like you wrote. I ordered a OEM sensor for $148, it will be here by Monday. The dealer wanted $235 for the sensor.

I finally put the new sensor in yesterday. Worked like a charm, engine light is off. I pull out of my driveway and had to make a quick stop. VSA light popped on along with the triangle with the ! ...so my victory was short lived lol

Post the code if there is one, for the VSA light and such. You could also try disconnecting the battery for a few mins, and see if that makes the lights go off. And then drive for a bit, to see if they come back on. Could be low voltage somewhere, but need more info for a help in diagnosis.

I will have access to the car on Wednesday. I'll try the easiest thing first, and disconnect the battery for 10 minutes and reconnect with my fingers crossed. If the lights are still on, I will hook up my OBD 2 scanner, but I'm not sure it that scanner will pull anything. I guess time will tell. I really think the quick stop did it. The lights came on immediately after hitting the brake. Thank you both for your suggestions, and I promise to update this board post during the week. Thanks again!
