error still there.
Then used another scanner- and it pointed to another wheel. Part replaced. issue resolved.
I checked my HF unit- and it also had the error code wrong.
Yeah - I remember reading you mentioning that. My HF reader is pointing to the rear driver's wheel, but the code description says something about "Tire Inflation", not "speed sensor".

So, I'm kind of trusting the wheel location, but not the description - the reason being: that's the wheel that blew out at 75 mph on I-95 almost two years ago.

But I guess we'll see if it's correct or not. Maybe I'll find a damaged encoder and it'll be obvious, but the way it's sporadically failing, I'm thinking it won't be the encoder.

Something I just thought of while reading your thread is that you mention having a blowout. Makes me wonder what condition all 4 tires are in, and if they all have roughly the same tread depth. Reason why I mention is because different tread depths = different wheel rpm at the same mph. The computer could read this difference in rpm as a wheel speed problem when in fact it could simply be that you need tires. Not saying this is it, just saying its something to look at.

The tires are good. And the delta mileage between the replacement Michelin Latitude and the other three Latitudes (~30,000-34,000 miles) is only about 7,000-8,000 miles IIRC. So I’d say it’s unlikely.

I suppose I *could* rotate the tire, reprogram the TPMS and see if the same code pops up.

Probably should stop by an Auto Parts store and see if they could read the ABS code for me, too ... see if it points to the same wheel. They'll probably say "we can't read ABS codes, only standard powertrain codes".

So I did, and they did (with an Actron reader), and it’s the same code as my Harbor Fake reader (C0045), but with a different textual description: theirs says “Left Rear Wheel Speed Sensor Circuit: Signal Amplitude Minimum”

Get this data point: I just completed a 2400 mile round trip over 6 days (almost constant driving) and did not see a single "Service Stabilitrak" message pop up!

If that rear wheel speed sensor (or the hub) is suspect, how could it rotate that many times and not throw a single code??
