41.... Primary Oxygen Sensor - Heater circuit malfunction? What the hell?

Is that expencive? What is it and how do I fix it? Can it hurt my motor if I drive it?

 

try www.sohfast.com for a new one.

They are expensive from the dealership - like $200.

It can hurt over time because your computer thinks that you are leaning waaaay out so it puts more fuel in. You will be running really rich and you will likely get bad gas mileage. :happysad:

 

Son of a... Is that the sensor that sticks out of the exhaust manifold?

 

If it is, its almost brand new.?....

 

Yup, primary is off of the front of the header and secondary is in the CAT.

 

Also why does it say Heater circuit malfunction? Could that be the problem and not my Oxygen sensor? Cuz I did buy a used blower motor a few weeks ago cuz mine went out again..

 

So how do I know what one is bad?

 

Your O2 sensor has a heater circuit. You can test to see if it's the sensor for sure by getting another one from a friend or something and trying the one you KNOW works on your car. If the CEL goes away, it's definitely the sensor.

 

Ok, so if I take the one out of my manifold, and replace it and the CEL is still on then I should take the one I took out of the manifold (the old one) and use it to replace the one in the cat... I get it....

Is the one in the cat hard to get to or is it a simple, jack the car up and take it out?

 

You shouldn't even have to jack up the car.
