repair / clean Oxygen sensor.

[mrbass]

greetings.
Time ago, in this forum (dont remember). I read about how to clean the oxygen sensor, an alternative to a buy new O2 sensor. I already searched for that post, but I dont found it. Someone can help me?

If someone knows about this I am very interested in trying it.

i found this

Expose the sensor tip to the torch till it's about to turn red, then dip the sensor tip quickly into water followed by cleaning the tip by blowing compressed air. This will make the carbon deposit to break free. We recommend repeating the procedure a few times until the carbon deposits are removed from the sensor tip.

And then this

http://mr2.com/TEXT/O2_Sensor.html just good info about o2 sensors

I think I will try to test my sensor sometime soon.

Isn't there a ceramic core on oxygen sensors?

[zero_gravity]

yeah pretty sure there is. just replace the thing if it needs it.

[bowtieguy]

some can be expensive, so what about carb/intake cleaner and compressed air?

[dkjones96]

Cleaning them like this will only work if the failure of the O2 sensor is premature. The catalyst in the sensor that causes the reaction that makes the voltage output will eventually wear out no matter how clean an engine runs.

Unless the engine was just running badly to begin with I've never seen an O2 sensor that had deposits caked on.

It should also be noted that one of the early causes of O2 sensor failure is water condensation.

I've also been told you can clean them by letting them soak in Sea Foam overnight.

I'd do a bottle of 99% Isopropyl in the tank and an "Italian tune up"

this is true. I recently got water in my motor, the motors ok, but the o2 sensor failed after I got the car running again.

I have a 1 wire o2. mines only $20 new. yes. I have a wbo2 and it really doesn't take that long at all for the ecu to go into closed loop. I'd be surprised if a heated o2 really put a car in closed loop any faster..,
