i have a 88 crx HF with obd0 b16 swap. and, i've been battling with this number 6 cel (coolant temp sensor)now for months and i just can't figure out what the hell is going on. so here's what i've tried so far.

-replaced water temp sensor...nothing
-tested wires with multimeter following all instructions in honda manual. everything tests good

-then i tried grounding the common ground wire coming out of the sensor straight to the engine. and i thought that worked. i wasn't getting a cel, vtec was working great, but....my tach,fuel gauge,and temp gauge stopped working. so, i replaced the fuse that was blown. GREAT, tach works...all gauges work, BUT...now i'm getting a number 6 CEL!!! WTF!

why the hell would i not get a cel and vtec would be working, and my car basically runs perfect, until i install a fuse for the gauge cluster??

the coolant temp sensor has nothing to do with the gauges. the temp gauge is a completely different wire.

someone help me pleeeeease!!! this **** is driving me crazy!

 

check to make sure you tail light harnesses are not corroded and dyr this is on the same circuit as tach, temp gauge ect

 

dyr? but why would this cause a code 6?
