O2 sensor heater DTC

[sapote]

Not always. I would confirm with a fuse tester. I had the same error earlier this year and it was indeed the f4 fuse.

No need to have special fuse tester.
Just use voltmeter to check all fuses should have 12v at both ends with key turned on.

This is the way…

Right- just anything other than a visual inspection

Checked the fuses with a meter, and all are good.

Took a screenshot within tory during my drive cycles. The usual suspects readied up. I'm expecting SAP to ready up within the next 2 cold starts, as I'm reinstalled the SAP hardware.

One thing I have noticed witin the Torque app is this...

Looks like Too Lean voltage threshold. Battery?

Running lean I would be looking at vac leaks, MAF, fuel pressure, injectors.

My Bad, it says Rich to Lean... does that matter?
I checked vacuum and all is good. I have the csl conversion, so no map sensor. Can I check fuel pressure and injectors in INPA?

look at your long term fuel trims in INPA. That should indicate whether you're running lean or rich. But usually either one triggers a check engine light.

The big concern to me is the o2 heater not complete.

Maybe the tool uses bad words to describe the problem subject and not really the heaters have problem.
Yes, I want to see the 4 fuel trims at hot engine idling. Better to get a log data file using OBDFusion. All owners should have one for less than $50 total hardware and app.

Ok will do, I'm on it.

The log should include these PID: engine temp in C, MAF in g/s, intake air temp, rpm, 4 O2 sensors, 4 fuel trims, SAP status, data sampling per second. Upload the file to Datazap to covert to graphs, then post the datazap link here so we can see the graphs.

This is one of my log for example, started with cold engine and get to operating temp. I didn't let the engine to idle enough before shut it off. You should let it idling for 2 minutes to get the stable data.

Got it.

I've been using the Veepak wireless adapter this whole time, so that's perfect. Downloading the fusion app now and will follow those instructions.

I'm about to log today. Did you buy the upgraded version of the app or did the free version allow you to log what you needed?

I bouhgt the app some years ago for $10 or so, didn't know there was a free version.
