Check ECTS Resistance

  1. IG "OFF" and disconnect ECTS connector.
  2. Measure resistance between signal and ground terminals of ECTS connector as the temperature rises.

    SPECIFICATION : 

    ECTS RESISTANCE SPECIFICATION

    Temp. (°C/°F) Resistance (kΩ) Temp. (°C/°F) Resistance (kΩ)
    -40 (-40) 48.14 40 (104) 1.15
    -20 (-4) 14.13 ~ 16.83 60 (140) 0.59
    0 (32) 5.79 80 (176) 0.32
    20 (68) 2.31 ~ 2.59    
  3. Are the measured resistance within specification?

    YES: 

    • Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure..

    NO: 

    • Substitute with a known - good ECTS and check for proper operation. If the problem is corrected, replace ECTS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
