I have a 2001 Honda Civic LX Sedan and have a check engine light on. The DTC code is spitting out P0118 ECT Sensor Circuit Input too high. The check engine light seems intermittent and goes away after a day and comes back after a few days. My guess is that the ECT is dying. So if anyone can point me to the location of the ECT sensor (preferably thru a picture under the hood) or give me an idea of other causes of such a fault?
