Does anyone know what the resistance should be to make an O2 simulator? I've looked for some online, but it's been a dead end. Looking for one for my 99 Blazer. Cat clogged, so I gutted it. Now I need a simulator.

 

Its not as simple as a resistor. An O2 simulator must have an active voltage output switching quickly and continuosly between 0.8 and 0.2 volts.
Besides, It wont work if it is the pre-cat O2 sensor.
If you still want to go ahead and build one I can email you the info.

 

I bought one for $40 from summit a while ago

 

The government is cracking down on the sale of these. Some sellers have been heavily fined. They may not be as easy to purchase any more.

 

The code given is from the rear sensor. If you could send me the info I'd appreciate it.
Send to bestracing (at) yahoo.com

Thanks,

D.J.
