So over the last year+ I've had a couple CELs, codes P203E and P24AE, that come and go but mostly stay on. One is for a bad exhaust sensor, and the other, a defective sensor in the DEF tank. Neither one affected the drive-ability (except disabling the remote start capability) of the truck, so I've ignored them. Now that I'm AEM updated and have this extended emissions warranty I decided to have the CELs addressed. Dropped the truck off last Thursday and picked it up yesterday. I was given a Jeep rental paid for by the warranty. The dealer ordered and installed a new DEF tank and exhaust sensor (they received a defective new sensor and had to order a 2nd one), now I have no CELs and I'm happy about that. I'm glad I was able to wait on these CELs until the settlement was over. These new parts are kind of pointless as I will be GDE tuning with my settlement money but it'll be nice to know that in the future if i had to return to stock for any reason I shouldn't have bad senors to deal with.
