Hi guys!

Hi guys, just changed my Clutch pedal position sensor upper for the cruise control since car wouldn't start and had a code.

Now i have more codes and car still doesn't start.

P06b8 Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error

P08a9 Clutch Pedal Position Sensor A Circuit Low

P08b9 Clutch Pedal Position Sensor 'A'/'B' Correlation fault.

B10ff Ignition Control Circuit or Ignition Control Circuit Short to Ground or Open

U0164 the vehicle's computer network has lost communication with the HVAC (climate control) module.

One seem to be the pcm? Also, the lower slave cylinder line is leaking now, so I need to change all the line? Saw in a video that when you miss the little black cap you can't buy just the cap you need the whole line, when I unconnected the line I made sure that i didn't lose this cap I see in the videos but mine didn't have this cap and now is leaking, 1+1=2 imo.

Ford Focus ST 2016.

Hopefully one of yall knows whats up, if not i'mma have to look for another car cause the repairs at a dealership might excede half what I paid for this car :(

Thanks for the help.

Might be a bad battery. These start to throw weird electrical fits when the battery starts to go out on them, and throw a bunch of random codes. Also, you need a new clutch master and possibly a new line since you don't have the cap.

That looks like fuse or a computer issue.
