O2 Sensor

I chagend my foward and rear O2 Sensor and the check light is still turn on I dont know what I else to do.

 

Welcome to TW Jose!

Can you provide some more info on your truck..how many miles, engine type, etc.

What led you to replacing the O2 sensors?

 

To help you the best we can, we need vehicle info(make model year etc), repair and maintenance history, and what the exact code numbers are for the MIL

 

The CEL generally takes a while to go away. It doesn’t happen right away after you change them out.

 

If you have not cleared the Code it will either go out next test cycle or the problem is still there.

Remember it is the complete circuit of the sensor.

Could be an exhaust leak between sensors depends what code you had

 

It's good to have your own code reader/resetter. I've used one like this $20 model from WalMart for years. I think I paid $55 for mine back when they cost a lot more.

What code number is popping up?

 

My car is a 2003 Tacoma V6 3.4 Liters have 224700 miles

 

usually the light goes out and it turns on but stays on more than it turns off
