[Gecko12314]

i just plugged in a obd II reader into my car cus i had a CEL and as soon as i plugged it in, the light went away but i checked the codes anyways and this code came up, P1143 and i checked http://www.obd-codes.com/trouble_codes/subaru/subaru-obdii-obd2-codes.php and its says its a "Pressure Sensor Circuit Low Input" wat does that mean ?
thanks

most sensors run off of a 5 volt referance voltage that is supplied by the pcm and then a signel voltage is sent back to the pcm by the sensor. So "low voltage is when the pcm recognizes the voltage comming back is to low. As in it is the voltage is being eatin by a malfunctions sensor or there is a short to ground in the circut. Preasure sensor is most likely a MAP sensor or Manifold Absolute Preasure sensor. I dont know what engine you have but if it doesnt have MAP then it has a MAF and the sensor may be a AC line preasure sensor, or even a auto trans hydrualic sensor. i would have to get more info to figure that out. well good luck
