Hey zub. 

Did you reset the car and the code came back? 

Here's a video that shows how to check the ohm  reading as well. Basically the code means the sensor is taking too long to heat up. So if even though 12 volts is getting from the battery to the sensor if resistance is too much or too little it could cause issues with heating it up properly.
