C1247 (brake stroke sensor?) and CEL

Last year I had the dreaded combo of red triangle,abs/brake symbol, vsc light, and the red "brake" warning. The main fault was C1247 and one related to the brake hydraulics. I fixed it with a full brake job all around (everything was well worn) and replacing the brake stroke sensor with a used one.

I just got the red triangle of death and the check engine light with C1247 as the error code at Auto Zone. My ABS module doesn't buzz excessively, i.e. when turning off or starting the car.

Has anybody had just the CEL and RToD with a C1247 error code? Any suggestions in light of what's already been done?

Thanks.

 

I got the car scanned with a generic heavy duty shop scanner. He found the current issue, C1247 and some old stuff. I'm hoping the serious ones are from a couple of years ago when I had the HV battery pack apart to replace a bad module...

He found: P3000, B1271, C1247, and P0A80.

I looked at the blink codes for the brake warning lights with a jumper across a pair of pins.

They were: ((!)) 47, ABS 42, and VSC 45

Oddly, the CEL and RTOD had turned off before I got to the shop. Also, the brakes aren't doing that pulsed engagement at low speeds (can't feel through pedal like ABS) as much as before.

 

Thanks. I had to take the dash apart 3 years ago to solder a capacitor in parallel to the flaky one on the combo meter... Hoping it's from that. If this car's holding codes that old, it has a hell of a long memory, LOL.
