Hey guys i made myself my own o2 sim from this thread
http://forums.maxima.org/showthread.php?t=481430

Like the title says is there any way to test this thing before i try it out on my car? An explaination would be nice too.

 

Hook up power, ground to it and watch the voltage get turned on and off. You should see .000v and then around .600v every few seconds, I think mine is every 5 seconds it turns on for 5 sec and turns off for 5 sec... and so on. Its so simple, I don't feel like ****n around with it to save measly 20 dollars thou.

 

if you have a firend in a dealership you can have them run consult on it and watch the data monitor from main ecm input signal

 

Or just use a simple multimeter and do the test that Blackbird suggested.

 

yeah thats what im gonna do this weekend when i borrow one to test that and to see which one of my coils are bad
