Long Tube Headers and Engine Light

[Chris@FreedomMotorsports]

Did you drive it at all? Load one smog tune, then drive it to work and back, get on it a few times, etc. Give the system time to clear it itself and then recheck when you do. If it doesn't work for one smog tune then try the other.

Just some things to look at, I'm sure you searched already.
And you are doing the battery disconnect after loading Tunes.
If not try it, it has helped me when I get a hiccup loading Tunes.


P0133 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0133
O2 Sensor Circuit Slow Response
What does the code mean? OBD-ii Code P0133 definition:
This involves the front oxygen sensor on Bank 1.
This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so,
or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.
Symptoms Sumptoms of OBD code P0133
You will likely not notice any drivability problems, although there may be symptoms.
Causes Causes of the OBD-II code P0133
A code P0133 may mean that one or more of the following has happened:
The oxygen sensor is faulty The wiring to the sensor is broken / frayed There is an exhaust leak.

Solutions:
The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor.

You will likely wind up replacing it but you should also consider these Solutions:

Check and fix any exhaust leaks Check for wiring problems (shorted, frayed wires)
Check the frequency and amplitude of the oxygen sensor (advanced) Check for a deteriorating / contaminated oxygen sensor,
replace if necessary Check for inlet air leaks Check the MAF sensor for proper operation



This P2272 trouble code refers to the post-catalytic converter O2 (oxygen) sensor on bank #1, sensor #2.
This post-cat sensor is used for monitoring the efficiency of the catalytic converter.
The converter’s job is to reduce emissions out the tailpipe.
When the signal from the O2 sensor is detected by the PCM as being stuck lean or biased lean, this DTC is set.

Possible causes
- Faulty O2 Sensor Bank 2 Sensor 2
- Exhaust leaks
- O2 Sensor Bank 2 Sensor 2 harness is open or shorted
- O2 Sensor Bank 2 Sensor 2 circuit poor electrical connection

P2272 Ford Description
The downstream heated oxygen sensor (HO2S) is forced rich and lean and monitored by the powertrain control module (PCM).
The test fails if the PCM does not detect the output of the HO2S in a calibrated amount of time.

What does that mean exactly?

My understanding in layman's term is that the PCM sends current to the O2 then reads the resistant values to determine if the cats have failed or are missing.
And it has to start giving the correct values when to O2 gets hot from the exhaust within a certain time period.
There is more to it of course what the rear O2 senses.
When the O2 reaches proper operating temp, the PCM can then determine the exhaust gases by the values it's getting from the O2 when it's collecting (sniffing) molecules.

So I wonder if I remove the O2 spacer on bank 2 sensor 2, it will get hot faster? Maybe move the spacer to the front (bank 2 sensor 1)?

Should I be revving the engine right after I start it so it gets hot enough?

I have not removed the battery terminal after the tune upload, so I will try that. But I don't thing that will fix my issue.

I have two smog tuned and have tried both ( @5star and a custom one from National Speed). I think I'll get a hold of @fordwop @svc and try their smog tune.

I wonder if you just have a bad cat. That may be the next step.

That's the worst next step I've ever heard! How do you diagnose that?

If you have the spacer in sensor 2 and don't have one in sensor 1, remove the spacer from sensor 2 and see if that helps. Without installing it on sensor 1. Troy is right though, it COULD be the cat itself. Best way to judge that though is at a muffler shop, they can hook up to the exhaust to test the cats for flow.

I was getting a code with clogged cats but it was neither of these (efficiency below threshold). Test for clog is to put a pressure guage on the front o2 sensor port. Plenty of videos on YouTube of how to do it.

I was still getting the same code with no spacers.
