Jared linked me this, I never knew this trick. Figured I'd pass it on.

I have to try this today cause mine is acting all stupid...i think
|
Typically they respond slower too. My Autometer gauge froze at 14.7 when its sensor died.
|
sweet, thanks :) im gonna have to test my zeitronixs one....
|
this should be a sticky! my car keeps going lean, i hope its the o2, its been running on leaded fuel since tuned so i imagined the o2 was probably going
|
Note that this is a WBO2 test, not for a stock narrowband, although it might be interesting to see results with a 4 wire.
|
Great thread. Mine has been acting screwy too. I am glad there is a semi-concrete way to test these finally.

I'm not convinced and I actually don't consider the AEM a reliable unit to begin with. A friend gave me his to repair (broken display), it actually displayed 14.5-14.7 WITHOUT the sensor connected!

Just about everyone uses the same Bosch sensor, what is different is how they read them and interpret the data. I think you can order a zeitronix that uses an NGK sensor. |
Also a very good read that I am sure most of you have seen, but for those that have not.

Almost all of them do this. My autometer wideband, AEM, and a friends Zeitronix all do the same.

this is a great test to know about.
a friend told me about it a while ago and I wasn't sure if it was accurate/legit. Now I know:) |
