2001 Ford Sport trac - ABS and Service engine light on - Why?

Question

Took it to Auto Zone and the OBD Trouble Code is P0402 - Exhaust Gas Recirculation flow Excessive Detected? anyone got an idea on a cure for the problem, that and I guess with the trouble code it won't read whatever they read to pass emissions - at leats that is how it was explained to me?

Answer 1

As per your warranty book :

(free download)
Certain emmissions related parts are warranteed for 8 yrs/80,000 miles.
If your vehicle is within these parameters, you might want to take it to a Ford Service Center (for a no charge fix), instead of Auto Zone.

As per your owners manual (pg 111):
********copy***************
ABS warning lamp ABS
The ABS lamp in the instrument cluster momentarily illuminates when
the ignition is turned to ON. If the light does not illuminate during start
up, remains on or flashes, the ABS may be disabled and may need to be
serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.)

So I would suggest taking it to a Ford Service Center, unless you are a qualified & skilled technician it is best to let professionals work on your vehicle. Auto Zone may give you the codes for free but their job is to sell you parts. And although there is nothing wrong with that, installing or repairing is better left to a proffessional.

Answer 2

This code is usually caused by a bad DPFE sensor (delta pressure feedback egr sensor) this is a dealer item best to have the dealer check it first, won't take long 1.0 hr
