How many miles are on your 2006 4.4L?

Have you had other trouble codes recently show up?

Are the O2 sensors original?

Understand that with the exception of the Evap Monitor the O2 sensors are typically used for ALL other Monitors. They are "Detectors" to tell the DME how the rest of the engine fuel management and catalytic converters are functioning.

The SAP system should be the very first Readiness Monitor to set and while I am do not know the 4.4L SAP system if it is like the system on the I6 engine, the Pre-cat O2 sensors detect if the SAP is running and lazy Pre-cat O2 sensors WILL cause the SAP Readiness Monitor NOT to set.

See graph attached below of Lazy vs Fresh Pre-cat O2 sensors monitoring the SAP system on an I6 engine. The fresh O2 sensors have the deep "V" behavior. And this data was gathered with the OBDFusion App.

I seriously HATE INPA for Driveability issues. You NEED a decent generic OBDII tool or App. The screen shot from INPA is a bit washed out and hard to read.

OBDFusion IS the App to get.

If you have a smart phone or tablet, get an OBDII App and interface so you can read the codes along with Live/Realtime or Freeze Frame data then you will know exactly what is going on with the engine fuel management system.

The OBDFusion App and proper VeePeak interface from Amazon are less than $40 for both for iProducts, less than $20 for both for Android.

OBDFusion for Android is $4.99 from the Google Play Store.

For Android this lower cost standard Bluetooth interface in the link below works well, but DO NOT try to use this with iProducts.

OBDFusion, for the iProducts it is $9.99 from the Apple App Store.

For iProducts you NEED a LE Bluetooth adapter which are more expensive. VeePeak now offers a LE Bluetooth interface that is compatible with OBDFusion in the link below. While people have used the Wifi adapter, I would HIGHLY recommend NOT using Wifi with iProducts, brings a lot of baggage and stability issues.

Ha, just pop in if a thread I posted in long ago notifies me.

I am sure I can help out, but you know the drill!

Do you recommend anything that is windows 7 based? Buying another interface puts me a few days back, where as I have a dedicated laptop and cable already.

I have 120k miles. I just complete a long list of repairs, everything has been replaced with bosch parts. I had one fault for the bank 1 after cat o2 sensor which I've just replaced. I assume the rest of the o2 sensors are from factory.

OBDFusion is the simplest and easiest App to use assuming you have an Android, iProduct or even an Amazon Fire tablet.

A somewhat comparable Windows based option with OBDWiz, actually written by the same developer of OBDFusion - https://www.amazon.com/ScanTool-OBDL...ywords=elmscan

Not sure OBDWiz will work with your INPA cable, just get the VeePeak interface and you might as well order Pre-cat O2 sensors as well because this is where this will ultimately end up going anyway!

But trust me, once you use a smart phone with a wireless interface in the car, you will NEVER try to use a laptop again. Additionally you will ALWAYS have to an OBDII tool with your if you keep the interface in the car, in the console, glovebox or door pocket.

BMW recommends standard 4 wire O2 sensors be replaced at 100k miles as they are "consumables". I generally never replace the Post-cat O2 sensors unless there is a heater fault or if the Catalyst Readiness Monitor is struggling. Often fresh Post-cat O2 sensors can detect degraded catalytic converters easier and once replaced if the converters are degraded, then P0420/P0430 start to pop when they did not previously.

You can get OBDFusion and the interface, $40 or less (under $20 for Android!) and run a Cold Start Log to see how active/lazy the Pre-cat O2 sensors are or you can just replace them as you they are beyond the recommended replacement interval at this point. If I had $5 for every problem car that I work on that still had original O2 sensors after 100-125k miles I would be a RICH man.
