H4 light

Hello, I am new here!
My name is Josh, I am a volunteer firefighter in Alaska. I have a 2006 Tacoma. But I have been having problems with my 4high and 4low lights continually blinking. This happened after I was driving and tried putting it in 4high from 2high. I got my codes checked, and no codes came up. Then I was driving around, put it 4high (light still blinking) and then the 4low light starts blinking as well. Turn my truck off, then just the 4high light comes on and stays solid. But when I go to put it in 2high the 4low light comes on and they both start blinking. I turned my truck back off, and on they are still blinking. Then I go back into 4high, then to 4low the lights still blink. Went back into 4high, lights are still blinking. Now I have my truck back in 2high and only the 4high light is flashing. When I shifted my truck, it would still shift into and out of 4high and 4low. Could it be the 02 sensor? Not sure what the problem is, if anyone can help that would be great! My email is sbnbarnett@gmail.com, or my phone number is 775-247-3118

 

Welcome. I don’t have a 2nd Gen but maybe this thread can help.

There’s a good convo about trouble shooting your 4WD issues.

 

Alright, and thank you!

 

Were you driving on pavement?

 

Yes I was, but the first time I went into 4high before the lights started flashing. I was off road
