2nd gen tacoma 4.0 P2241

Good morning, new member here.
Ran into a problem after and engine swap.... the truck runs great but have a p2241 code I replaced the 02 sensor (driver side upstream) with denzo one. code immediately comes back on. here is some live data if someone can help me out thanks

 

If you can verify the sensor is good (you can swap the upstreams and see if the code follows the sensor or not) then you likely have a shorted wire. Are you sure you didn't pinch any wiring?

 

Thanks for the reply , I put a new one in and got the same code, the wires look fine nothing pinched. kind of stumped atm other then on the file I posted the MA reading is 0 on the bank I'm having a problem with.

 

Gona have to check your wiring then, you either have an open or short to ground on one of the AFR signal wires, I left the wiring diagrams and the code criteria/testing in my earlier post. If you have any questions just ask.

 

Just kinda gave a tiny tug on the wires and this one came off so I'm hoping it's the signal wire ...lol I'll give and update after I reconnect thanks

 

That will do it
