Need help with fault codes

These are the codes I am getting and need help figuring out what I need:

17704 - Temp sensor
17866 - EGT Sensor #2
17539 - O2 sensor bank 2 sensor 1
17521 - O2 sensor bank 1 sensor 1

Could use some help with the parts models and pricing. Much appreciated

what are the codes specifically. Based on the info you gave all I can recommend is to replace all of those sensors.

Temp sensor is about 60, two 02s will run you about 150 each, the EGT can run 500 or more.

Here you go, these are all the sensors that are indicating as bad.
Click here for pricing and partnumbers.

I would recommend you replace the o2 sensors and the coolant temperature sensor first, then see if the EGT error comes back.
