MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1187 - Sensor Voltage Supply Failure - Continued 5. Disconnect sensor harness and actuator harness from engine ECU. Place ignition switch to ON position. a. Measure voltage between engine ECU sensor port pin 18, pin 25, pin 45, and ground. Voltage should be 4.75-5.25V. If voltage is not as specified, replace engine ECU (WP 0078 00). b. Measure voltage between engine ECU actuator port pin 19 and pin 29 and ground. Voltage should be 4.75-5.25V. If voltage is not as specified, replace engine ECU (WP 0078 00). USE TEST LEAD KIT P/N 3822917 ACTUATOR PORT: PINS 19 AND 29 TO ENGINE BLOCK GROUND SENSOR PORT: PINS 18,25,45 TO ENGINE BLOCK GROUND 4.75-5.25V 4.75-5.25V
