MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1227 - Sensor Voltage Supply Failure 1. Place ignition switch to OFF position and disconnect sensor harness connector from engine ECU. a. Inspect engine harness and sensor connector for dirty, corroded, bent, broken, pushed back, and extended pins. Clean and repair connector(s) as required (WP 0111 00). b. Check engine harness and engine ECU connector for dirt or moisture in or on connector and for missing or damaged connector seals. Remove dirt and moisture from connector. Replace missing or damaged connector seals (WP 0111 00). 2. Disconnect sensor harness and actuator harness from engine ECU. Place ignition switch to ON position. a. Measure supply voltage out of engine ECU sensor port at pins 18, 25, and 45 to ground. Voltage should be 4.75-5.25V. If voltage is not as specified, replace engine ECU (WP 0078 00). 4.75-5.25V 4.75-5.25V USE TEST LEAD KIT P/N 3822917 ACTUATOR PORT SENSOR PORT
