riff raff Posted October 16, 2018 Share Posted October 16, 2018 Has anyone done the TSB 14-0204? https://testing-public.carmd.com/Tsb/Download/105643/tsb14-0204 My 2014 3.7L FWD continues to set the PO430 SES light. My mechanic is afraid to replace the cat (Bank 2) until this TSB is completed. An aftermarket cat from him is around $250, guessing $1200 from the dealer. He says that the computer reflash for the TSB might even resolve the issue. The code pops up radomly, sometimes after 100 miles, other times going 300 miles or so to the light comes on.

How many miles on your car? Our cars have a 5 year/60,000 mile Bumper to Bumper Warranty, 6 year/70,000 mile Powertrain Warranty, along with the extended emissions system warranty. Certain emissions equipment is covered to 8 years/80,000 miles. Before you do anything, read your Warranty Booklet and check with your Dealers Service Department first to see if your car is still covered under warranty for this issue. Keep us updated and good luck. Edited October 16, 2018 by bbf2530 Quote Link to comment Share on other sites More sharing options...

I am sure that some have needed the TSB performed, but not sure how that answer helps you or not. In my opinion, if your mechanic thinks you should have the TSB performed first, then you should do it. The problem is not necessarily even the catalytic converter. Could be something as simple as an oxygen sensor. Here is my opinion again: According to the TSB link you provided, the total labor time for the reprogramming and catalytic converter replacement is 2.8 hours. I would guess the programming alone should be no more than 1 hour labor cost. I would have the TSB performed by your Dealership and then let your mechanic replace the catalytic converter if necessary. The longer you drive with the issue, the more likely you are to cause further damage (although you have already driven 20,000 miles with the intermittent CEL). Let us know how you make out and good luck. Quote Link to comment Share on other sites More sharing options...
riff raff Posted October 17, 2018 Author Share Posted October 17, 2018 That' is definitely the plan. My buddy checked out the data from the operating system and saw no issues with the cat functions. Hopefully, with the erratic light, it is just a reflash necessary. My local dealer said that runs around $170. I have an appointment set for Thursday. I was hoping that one of the techs here might see this thread and comment. It looks like the 3.7L/FWD combo is the last popular. Quote Link to comment Share on other sites More sharing options...
riff raff Posted November 2, 2018 Author Share Posted November 2, 2018 (edited) Update: I had the car at my local dealer. They said a reflash wouldn't solve the problem, and my Bank 2 catalytic convertor was bad and the Vapor canister purge valve. They quoted $1400 for the job. The dealer charged me $173 to diagnose. I ordered the parts from Rock Auto and had my buddy do the job at his service station. $200.79 - Catalytic Convertor $25.89 - Canister Purge Valve While he was in that area, I thought he might as well replace the Vent Valve as well, and they recommended replacing the wire connector $15.00 - Canister Vent Valve $28.79 - wire connector So - $312.54 - Parts (w/shipping & tax) $450.00 - Labor $762.54 - Total My buddy said while there was just enough room to get the cat out/in but it wasn't exactly an easy job.
