Looks like I spoke too soon. Check engine light is back. Made it almost a week lol.

Has anyone tried moving the second 02 sensor out of the way to avoid the code?

 

Have you confirmed that your air pump is working? It cannot be the relays as you have a brand new RCM in there.

When I had this problem, my air pump was fried along with the air pump relay so I ended up getting a new RCM, and used air pump off ebay. The problem for you is, finding an srt-6 air pump used is almost impossible now. I was lucky.

 

Is this a good time to mention that if you have an android tab or phone you can use a dongle ($12 - get a mini) from Amazon and Torque Pro ($5) from the play store and monitor/log the output of all four O2 sensors ? Quick way to determine if that is your problem.

There is nothing equal to having the right tools for the job.

ps P0410 Possible Causes
AIR PUMP VOLTAGE SUPPLY CIRCUIT OPEN
AIR PUMP VOLTAGE SUPPLY CIRCUIT SHORT TO GROUND
AIR PUMP GROUND CIRCUIT OPEN
CRACKING, MISSING, MISROUTED, OR PLUGGED VACUUM LINES.
AIR PUMP SWITCHOVER VALVES
AIR PUMP RELAY
AIR PUMP
POWERTRAIN CONTROL MODULE

How did you get on O2 sensors ?
