P0180-FUEL TEMPERATURE SENSOR SIGNAL VOLTAGE TOO HIGH

For a complete wiring diagram Refer to Section 8W

• When Monitored:

  With the ignition on.

• Set Condition:

  The Fuel Temperature Sensor signal is above 4.95 volts for 0.5 seconds.

Diagnostic Test

NOTE: If multiple DTCs are present, the most likely cause is a 5-Volt Supply or Sensor Ground circuit shorted to voltage or ground. Refer to the Service Information Wiring section for circuits that would affect multiple DTCs.

NOTE: If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.

NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.
