Crankshaft Position Sensor: Echo

  1. Remove passenger's side engine cover for access to crankshaft pulley. Disconnect crankshaft position sensor electrical connector at crankshaft position sensor. Crankshaft position sensor is located on front of engine, near crankshaft pulley. See Figure.
  2. Using ohmmeter, check resistance between electrical terminals on crankshaft position sensor. Ensure crankshaft position sensor resistance is within specification. See CRANKSHAFT POSITION SENSOR RESISTANCE  table. Replace crankshaft position sensor if resistance is not within specification. See CRANKSHAFT POSITION SENSOR under IGNITION SYSTEMS in REMOVAL & INSTALLATION - 4-CYLINDER article. Reinstall crankshaft position sensor electrical connector.
