is it okay if i wet the sensor that is next to the one wire sensor that is located on the head on the dizzy side?

i'm planning on cutting it off, wetting it down, and re-wiring it back up.

all kinds of oil got into it and it makes my car temperature gauge in the cluster go crazy and makes it think its overheating when its actually fine.

but of course before i put it back on, i'm going to let it dry up.

 

wet the sensor?

 

i want to fully hose down the clip because inside of it, its full of oil.

 

use electrical parts cleaner

 

yeah thats wgat im about to do right now

 

so i used electrical parts cleaner.
it worked.

it only shot up one time though when i turned it to the on position but as soon as i cranked it over it went back down to the middle...
.kind of random,
hopefully it stays where its supposed to be at.

 

The 1-wire not 2-wire sensor under the distributor sends the temp signal to the gauge.

 

hey! i think you've helped me out before.
but thanks for correcting me.

yeah, but the one that was full of oil was the 2 wire one.

 

The oily one sends coolant temp signals to the ECU but has nothing to do with the dash gauge temp reading. If the dash gauge is your problem, disconnect the 1-wire sensor, clean if necessary, and reconnect tightly.

 

well weird thing is, i cleaned that one up and reconnected it and my needle went back to normal.

 

Probably a coincidence.

 

wait.... like you said, the 2 wire one tells the ecu the temperature of the coolant.

if the 2 wire one is oily, its going to think its way hotter than what it is.

therefore, the one wire one is going to display your car is on fire.

sorry if that makes no sense.
it made sense to me. :smile:

 

The 1-wire and 2-wire sensors are indepedent, that is they don't talk to each other.

 

hm, weird then.
