If the reading is within the standard, remove the ECU and
check the wiring for continuity between main harness con-
Disconnect the ECU and sensor connectors.

If the wiring is good, check the ECU for its ground and
power supply (see ECU Power Supply Inspection in the
Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU
