    m20b25 coolant sensor

    i recently had a new head put on my car after the timing belt broke. when the job was finished the car was rough to start and i had to hold the accelerator to get the car to start. My check engine light is on and the temp gauge is not working. once the car warms up it works great but until then it idles rough. I think its a busted coolant sensor. Can anyone tell me where this sensor is so that i can replace it.

          Hard starting, inop temperature gage, and a CEL could mean that the connections for the DME and gage sensors are swapped.
          The car makes it possible, but the driver makes it happen.

            ^ one is a two pin and the other is a one pin connecter right? and the the connecters also are the same color as the sensors they plug into correct ?

              yeah, they are color coded, but I think you can still plug them into the wrong ones. I have no idea how you do that, but it could be done.

              I've also seen it where people cut off the plug for the blue sensor and put on one of the sensors from the eta. doh.
