These will help.
Thanks.

P0141 indicates oxygen sensor 2 in bank 1. Bank 1 is on the side of the engine where the first cylinder is.

Your firing order (and the location of your cylinders) can be found here:

And further reading on the code you pulled can be found here:
http://www.obd-codes.com/p0141

P0141 is an 02 Sensor Heater Malfuncion (Bank 1 Sensor 2)

Four seemingly unrelated fault codes;
P0526 - fan speed error
P0141 - downstream O2 sensor lean condition
P2135 - Throttle position sensor fault
P2138 - Accelerator position fault

You need to have a qualified technician diagnose this with a highend scan tool, maybe there is a possibility that a reference voltage is off spec.

Hi, the P0141 is the O2 sensor, more info @ http://www.obd-codes.com/p0141 . Also P0506 code is Idle Air Controller problem - http://www.obd-codes.com/p0506

Which O2 sensor did you replace?
P0141=O2 Sensor Heater Circuit Bank 1 Sensor 2,
this is on the drivers side,and the sensor after the converter

Air condition is blowing hot air all the time
