Changed Engine Pipe Now CEL Code P0141

[brooklyn99corolla]

Had the engine pipe changed now the CEL is on Code P0141, 02 Sensor Heat Circuit Malfunction (bank 1 sensor 2) is this sensor near the engine pipe? could it just be disconnected? the live data reading from my scanner reads 02S12 (v) 0.00 (%) N/A the 02s11 does get a live reading. Do i just have to change the sensor? Anyone have the part number?

engine pipe?

Do you mean exhaust?

[brooklyn99corolla]

yes replaced the pipe from engine to exhaust

You didn't change the O2 sensors with the catalyst converter swapped out? Change out the O2 sensors if you haven't done so.
