ECA 61 - No Code (Idle Switch)

  1. Check continuity across idle switch terminals at idle. Continuity should not exist. Check continuity at 1160 RPM. Continuity should now exist. If continuity does not exist, adjust or replace idle switch as necessary.
  2. Check continuity between idle switch Black wire terminal and ground. If continuity does not exist, repair idle switch ground circuit.
  3. Check idle switch voltage at ECA terminal 1E. At idle, voltage should read 12-14 volts. At about 2000 RPM, voltage should read 0-2.5 volts. If voltage is not present, check for opens or shorts in wiring between idle switch and ECA. Repair as necessary. Go to ECA 64  .
