Emissions codes... should I replace PCM

[Ressa]

I am getting codes for all the emissions sensors using BlueDriver. I already replaced the egr valve based on dealer recommendation. Is it possible that the pcm is the problem instead of all the sensors? (2010 mustang , v6)

Need way more information to properly answer.
What specific codes are you seeing / what running problems (if any) are you experiencing?
Any mods / tune or bone stock?

[Ressa]

It's bone stock and there doesn't seem to be running issues. Here are the codes
P0141, P0161, P0135, P0155, P0443, P0403

Appreciate any advice!

Did you carefully check all fuses? Bet they are linked together / one of them has either a wiring issue or internal short.

[Ressa]

I did not check the fuses. Ok, I will check them and see what I find.

[Ressa]

All the fuses check out ok, especially the emissions fuse ...

To be clear, I only checked the pcm related fuses

[ZR]

Check em all to be sure.
You use a test light on them?

[Ressa]

Augh... no, dammit. I will get one

[ZR]

Cheap but reliable test light is your best friend / most reliable way to check fuses.

[Ressa]

Done, used a continuity tester on all fuses. All are good

[Ponyryd]

Continuity tester is not checking power, just the integrity of the fuse, which doesn't really help. If you're using a voltmeter, set it to V and see what you get.

^ Exactly that.
