If the reading is in specification, check the ECU for its ground and power supply (see ECU Power Supply Inspection).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).
If the reading is out of the specification, remove the ECU and check the wiring for continuity between main harness connectors.
