Load Sensors

  1. Disconnect connector between load sensor and ECB. Connect voltmeter to ground and female terminal (wire 113 or 115) of connector half leading to the ECB. Voltage should be 8 volts or more. If voltage is less than 8 volts, check wire 113 or 115 for shorts.
    NOTE: Load sensor connectors are next to injection pump and are covered by a piece of tubing.
  2. Partially connect connector pins between load sensor and ECB. Expose connector pins but do not break electrical contact. Connect voltmeter to ground and to exposed connector pin on wire 112 or 114. Move swing arm until load sensor is covered by target area. See Fig. 3.  Voltmeter should read 5 volts or more. Move swing arm until load sensor is uncovered by target area. Voltmeter should read 2 volts or less.
  3. If the voltages in step  2) are zero or about equal, connect voltmeter to ground and to exposed connector pin on wire 113 or 115. Voltage reading should be 8 volts or more. If not, replace load sensor.
    NOTE: When replacing a load sensor, the position of sensor in relation to target area must be adjusted. See LOAD SENSOR ADJUSTMENT.
