Im removing my motor so I can build my bottom end, and while I Was removing the engine harness I couldnt get the wires off of this sensor and I ended up breaking it. I unscrewed the sensor and coolant started coming out so I put it back in. It is below teh vtec solenoid. Here are some pics.




TIA!

 

tw switch, its like $25-30 at the dealer, u can get it off any honda head. I broke mine and justgot a new one since it was cheap

 

sorry, but I cant even think of what tw means....

 

i think its the one your cluster reads for the temp, but not 100% positive

You are correct. It is called the Engine Coolant Temperature Sensor (ECT sensor).

 

where the hell is it in here?: http://www.hondaautomotivepart...EC%29

 

its part number 37870-PJ7-003 and listed under "water pump/thermostat" slhonda.com is a better site to look for things, u can click the number on the pic and get the part number and name

 

sweeeeet. thanks man

 

Go to a junkyard and grab one off of any honda/acura.. They are all the same..

actually the signal is sent to the cluster from the temp gage sending unit. It has a yel/grn wire with a female bullet connector on the end.

Also you can still drive with it like that for the time being, only thing is your temp gauge on your cluster isnt going to work..

 

I see. I'll justyank one from a junk yard later on after the engine build is done. im not really worried about it right now, just was curious as to what it was...thanks for the help guys!

 

Not only that, the ECU uses it to calibrate cold fuel enrichment.
