P0188 2000 FORD F150 - Engine Fuel Temperature Sensor B Circuit High Input

Repair Importance Level: 3/3
Repair Difficulty Level: 3/3  What does this mean?

Possible causes

  • Faulty Engine Fuel Temperature Sensor
  • Engine Fuel Temperature Sensor harness is open or shorted
  • Engine Fuel Temperature Sensor circuit poor electrical connection

Tech notes

The comprehensive component monitor (CCM) monitors the EFT sensor circuit to the PCM for high voltage. If voltage were to exceed a calibrated limit and a calibrated amount of time during testing, the test will fail.

When is the code detected?

An excessively high voltage is sent to Powertrain Control Module (PCM) by the Engine Fuel Temperature (EFT) Sensor.

Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
