2000 Ford Taurus Problems
RepairPal has identified the most common problems with the 2000 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.
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.
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.
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 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.
While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.
Bad motor mounts can cause the motor to move excessively, which pulls on the MAP sensor vacumn hose every time you step on the gas pedal. This either weakens the hose so it collapses (causing low vacuum flow) or pulls the vacuum hose that connects the intake manifold to the MAP sensor completely off of the sensor. When the hose is disconnected from the MAP sensor, a full rich condition will result.
