Check engine light after replacing air filter

[Paul Gregory]

Hi,

I have scanned the newsgroup for this problem and havent seen any
posts... so here goes.

I changed my air filter today ( 1996 V6 Ford Explorer ) and later
noticed the Check enginge light on. I tinkered a bit with plugs to the
sensors and stuff, but don't really know what they all are.

My question is this, is there a common problem when changing the air
filter on these trucks, bumping the sensors or crimping tubes?? And also
do i need to get the light reset? Maybe i fixed the problem and the
light needs to be reset?

Any help would be great.
Thanks in advance.

If the old filter was pretty dirty, the sudden change in airflow the
engine see's could make it set a code.
Could also be the MAF is dirty.
MAF is the sensor right after the air filter that is part of the intake
tube. Clean it with some spray intake and throttle body cleaner, then
disconnect the battery for a couple minutes to reset the codes.

Suggestion: re-set the computer by disconnecting the battery for a
few minutes. The light may go out as the engine digests new data from
its sensors.

I took it to my mechanic and he said it had two codes. One was the EGR valve
sensed high flow, and the seconf was something to do with the reverse sensing
unit ( said could be caused by going through reverese too fast. He told me to
drive it around and let it finish its self diagnosis cycle. The light came
back on and then went out maybe 10 minutes after it came on. Any idea what
could cause these problems, and how I myself could test this? It is an EEC V
computer so i cant do the jumper test :(

Thanks 4 any help

If you have a laptop, check out http://www.obd-2.com/
A scan tool that costs ~120.00.
If the EGR is sensing high flow, it could be the hoses to the EGR sensor
are split, or the EGR valve could be stuck open.

Just to let you know...

It was the EGR valve sensor. I had it replaced and now all is fine.
It cost 125 bucks, Sensor: $60
Labor: $58

Does this sound reasonable? ( they only charged me for 1.25 hours of labor
but i waited for 4 hours!)

I replaced my sensor and it took about 10-15 minutes. But this does not
include waiting for the parts counter, walking back and forth between the car
and parts counter, bathroom break, etc............
