1998 Civic EX (D16Y8) coupe stock. A/T. 148k

Have a P0135 CEL and followed this: Part 1 -How to Test Trouble Code P0135 (1995-2000 Honda 1.6L) to check it.

Results:
Fuse 15 intact and not blown.
BLK/YEL reads 12v.
BLK/WHT reads 4.3v..( should be 12v).
o2 sensor pins 3 & 4 reading 13.6 ohms (acceptable range is 10-40 ohms).

Live in Florida so no worry of emissions check.
Is there a fix or bypass for:
"If your multimeter still doesn't register the 10 to 12 Volts DC, then the most likely cause of this missing ground is an ‘open’ in the BLK/WHT wire between your Honda Civic's PCM harness connector and the O2 sensor's harness connector."

Should I wrap the harness near the bracket with electrical tape anyway to prevent possible fuse blowing?

Ohm test the heater element.

How to do that?

I measured resistance across C&D of oxygen sensor which read 13.6 ohms.

Are these harnesses connected correctly under the intake manifold? Is the gray piece that is connected to the blue piece just a cap?
Should I wrap electrical tape around them?

Side question if permitted...Is the tension on my timing belt correct or too tight?

Sensor Ohm reading is fine. Test heater element wire that runs to ECU for ground and short.

Reconnected o2 sensors and cranked turned key to "ON" (2nd position) for 10 seconds..CEL gone. Started engine CEL gone .. timing belt too tight. Retensioned and and now seems to be slightly loose but, not skipping at all.
Will update timing belt to this thread: https://honda-tech.com/honda-civic-d...ilure-3250014/

Sup "dad".

Anyways when tensioning the best you need to align all timing marks (crank and cam gear), loosen the tensioner 1/4 turn, turn the crank 3 teeth and then tighten the tensioner. DONE, BEER, IMAGINATION HIGH-FIVE.

Jimi - I locked this thread because you previously created one for the timing belt issue.
