Code and hose Help!

Hello people, my check engine light is on and I need to have my 2001 Tacoma inspected by the end of April. I bought a code scanner and it seems to show different codes everyday but only 2 thank god. The latest codes are P0125 insufficient coolant temperature and P1135 Air/Fuel sensor Bank 1 Sensor 1 heater circuit malfunction. Also there is a hose not connected at one end. It originates at the plastic holder for the air filter then theres a hose connected to a metal pipe and another hose comes off that metal pipe and that is the hose not connected at the end it's just hanging please help.

 

pics would help
and Welcome from Murphy N.C.

 

Here is the picture of the hose.

 

I would say it is your afr sensor that needs to be changed

It is located near your front catalytic converter, you can change it out in 5 mins

This should take care of your check engine light

 

i'd say that hose is suppose to connect to another pipe that goes from the fuel tank to the airbox. its suppose to vent fuel vapors and send them to the airbox. at least that is my guess. and if it isn't connected that may trip a code

 

Thank you for all your help after a new Air/Fuel ratio sensor, oxygen sensor. coolant thermostat and ECT sensor there is no check engine light on. I had them do the inspection and hopefully no more major repairs until next year.
