bump..i need to know to!

 

Yes, there is heater element inside the O2 sensor. You can replace it (the whole O2) and hope that's the problem. Or you could get a meter and measure the heater resistance to see if it really is bad and then go from there.

Spec is 15-40 ohms.

 

Get a HELMS service manual too so you follow the troubleshooting steps for solving a code 41

You forgot to mention the measurement should be taken between the 2 black wires.

So instead of just picking up my slack, you point it out?

You forgot to mention that the O2 sensor needs to be disconnected from the main engine harness when making this measurement.
