So I went to the Chrysler dealer for an emissions test. Failed due to p0410 and p2098. Dealer said I needed Oxy Sensor, I replaced all. p0410 is gone. Dealership also said I needed to replace the main engine relay 5099007AA. Auto part said that the main relay should not be causing p2098. Cleaned the MAF and I still get p2098. Should I break down and buy the main engine relay?

 

Reference the PO410 fault.

No you shouldn't buy the main relay (RCM).
You should send it to me (as MANY others have) to:

and for just $25 I'll inspect, redo bad solder joints, perform the Me So Horny mod (horn works w/o key) and replace the Air Pump relay (the cause of the PO410 fault). I will then test your RCM in one of my cars. Then I will mail back the RCM to you via USPS Priority Mail (2-3 day). In most cases I get the RCM back in the mail the day after I receive it so yer looking at about a week total. If you want the package insured please include an additional $8. FYI, In the couple/few years that I have been doing this only one was lost in the mail.
Please email your address to me also.

Are you sure you have the remaining fault code correct?
The P2098 is related to the oxygen sensors and the P0410 to the secondary air pump.
Having replaced the oxygen sensors this should have or could have fixed the P2098 code, the P0410 is normally associated with failures to the air pump, its solenoid or the blue check valve.
