Table 3. Error Code 1582 - Fuel Inlet Restriction Sensor Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1582 - Fuel Inlet Restriction Sensor Circuit Failure 1.  Place ignition switch to OFF position  and  disconnect  fuel inlet  restriction  sensor  from engine harness (WP 0093 00). a. Inspect fuel inlet restriction sensor connector and engine   harness   connector for   dirty,   corroded,   bent, broken,  pushed  back,  and extended pins. Clean and repair connector(s) as required (WP 0111 00). b. Check fuel inlet restriction sensor  and  engine  harness 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).
