Has anyone tried to use O2 sims for a GM vehicle on a Dodge vehicle with no cats. Specifically a 03 Dodge 1500 pickup. I know the connectors are different, but it looks like the downstream O2s are a 4 wire heated O2 sensor. They could be hard wired in. If not, what are you Dodge guys doing about the SES when running without cats?

 

Just pull the rear sensors out and wrap them in aluminum foil. Then ziptie them off to the tranny or stick them under the heat shield. It's worked for me for quite a while now, as far as I know there's not any O2 sims that work on these trucks. You can also buy two sparkplug non-foulers and screw them into the O2 bung, this locates the sensor out of the airflow and should keep the CEL off.

 

I did find some O2 sims made specifically for Dodge applications. $125 for a pair. They are not a sponsor here so I can't say where I found them. I may try the foulers first since that would be cheaper if it works. Thanks.

 

Shoot me a PM. I know of a few companies that offer them for the hemi's but most of them don't work. It's kinda hit or miss.
