Ok, I am working on a 94 Civic Hatch with a H22 in it...

It is throwing a Water Temp Sensor code ... i have replaced the water temps sensor with a new one, and it is still throwing the code. Checked the wiring it is all good. what else could I check . Yes I have searched, but no luck....

I changed the water temp sensor on the side of the head under the dizzy...

thanks in advance...

The 2-pin one? Has the air been bled out of the cooling system?

 

It has a single wire that runs to it... I never knew that bleeding the air out of it... do i just have the car idling and open up that valve to let the air out???

That one just operates the gauge. The 2-pin sensor is the one that send the ect signal to the ecu.

Engine off and open the bleeder screw while adding coolant. Might be your problem if you haven't done it.

 

the two pin sensor is right by the one wire that operates the gauge?

 

TTT FOR SOME HELP...

yes, replace it and then reset your ecu by pulling the hazard fuse out for 10 seconds.

 

just take you car out for a nice little drive to go through a full trip cycle of your ecu, then if the problem is fixed the light will go off
