Ford Taurus Problems
RepairPal has identified the most common problems with the Ford Taurus based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
Multiple owners have reported instances of the automatic headlights not functioning properly. Possible causes are failure of the sunload sensor, the light switch, or the Smart Junction Box (SJB). Professional electrical diagnosis is recommended before replacement of any parts.
The 2008-2016 Ford Taurus and Taurus SHO with automatic climate control may have a problem with frequent fan speed changes when using the heater or air conditioner. Normally, the fan speed changes only to maintain a selected temperature, but when the fan speed changes frequently and needlessly, there is an issue with the fan speed control unit.
The fan speed control unit, sometimes erroneously called the blower motor resister, regulates the speed for the blower motor in order to maintain the temperature set by the driver. When it fails, the fan will run at random settings, and the climate control will be inaccurate.
Note: this does not affect the temperature of the air that comes from the vents, it affects the amount of air that comes from the vents.
The repair is simple, and quick. The control unit is located behind the glove box in most models, and removal and installation takes only minutes.
Also note: this only applies to vehicles with single or dual automatic climate control.
The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.
The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.
A Lack of power, poor fuel economy, and black smoke from the exhaust can be caused by a defective MAP (manifold absolute pressure) sensor.
Worn motor mounts can cause the motor to rise during acceleration, causing a clunking noise and possibly damaging the AC hoses. Damage to the AC hoses can cause a loss refrigerant resulting in no cold air from the AC. The motor mount will need to be replaced prior to repairing the damaged hose or the problem will continue.
The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.
