Question about 2002 Ford Taurus
Posted by Anonymous on
I have to put thus little bit of info in here. I just had to deal with an 02 Taurus that would not start. Managed to get it to start by holding the gas pedal to the floor and when it finally fired up it blew the DPFE hose off. After a while of it sitting in the garage I decided I would just keep the gas floored and after a few seconds it came around. My suspicion is that because this car only runs for a few minutes at a time, moisture accumulated in the CAT and froze when temperatures got into the single digits. My conclusion is make sure the vehicle get to operating temperature during cold weather to prevent exhaust freeze-up.

That is the (Differential Pressure Feedback Exhaust) - e.g. EGR Valve. You shouldn't have any trouble finding it. There is usually a metal tube from the exhaust manifold going to it,as well as one or two vacuum hoses.
It has to also, direct exhaust gas into the intake,so there is your key.

off, EGR valves seldom fail. Yours probably had nothing wrong with it in the
DPFE sensors, OTOH, have been a problem for Ford for years. Best results have been obtained with the upgraded Ford replacement.
Make certain the hoses to the DPFE sensor did not get reversed and are not clogged if you have the non-plug-on version. If the upstream hose is getting blown off or is over-pressurized, clogged cats could be the issue.
Check the Vacuum line at the EGR valve for vacuum at idle and while reving the throttle. It should not have and vacuum while the vehicle is not in motion.
It should not have any vacuum while the vehicle is not in motion.
If it does, you'll have EGR flow at the wrong time which usually causes idle problems and low speed stumbling/misfires. EVR solenoid is either dirty or sticking open. Try popping the cap off and cleaning the filter element and the top of the valve with compressed air.
It takes a minimum of two drive cycles in which OBDII runs the EGR test for it to turn on the MIL if there are failures.
When the code is cleared typically you have to run through a specific cycle. With Ford a normal driving can take a couple of days to a week or more. There is page that lists the cycle and you can run through it about 45 minutes
