Are the test something I can do on P0488 EGR valve .

the 2.0L engine, in uSA? (6 engine world wide even k11/12)

egr tests and steps, and cleaning or extensive
the valve must not stick
the total path not blocked. end to end.

488s may mean just that.
it's a 5 wire motor driven EGR valve
clean it first
some will reset and cycle key on, off.
use that trick to clean it, and see if it works.

many newer cars the EGR has a read back device, direct. it has variable resistor in the main valve, that tells the PCM that the valve moved to the correct spot.
if this fails, the valve is stuck.
reading up on 488s, tells you what the test does.
i dont have that book,
if the motor works and is not stuck then the path is blocked,

the exhaust path, this can be a small horror to cure.
once you do one, then 2nd will not be fun.
after you look like a carbon covered monkey.
Some take a full weekend to do at home.
see these 5 pins on back of main egr.
there is a motor there, but one pin might be
egr feed back sensor. not sure.
, one way to test it. is to unscrew it.
and clean it then cycle the key connected
and look inside to see if it moves inside.
the ECU resets it and at key on, you can watch it.
if it seems to work ok,, the path is blocked, sorry

What are the probable causes of DTC P0488?

The most likely cause is that the EGR valve position sensor is defective. But testing is required to confirm this.

How can I reset my '99 caddy sts's computer in order to pass my smog

You can use a code reader/coder clearer handheld device at any of the major auto dealers to clear the code. The device plugs into your dashboard on the left side of the steering wheel at the bottom.. Normally, you can clear the code and drive for about 15 minutes (maybe more if you are gentle on the gas) before the code appears again. These code readers cost about $80 to $100.

P0488 fault code on a 2008 outlander

just had this on my 2007 2.0 did outlander, replaced the egr throttle body which cleared fault code p0487 which i also had, but p0488 was a little more tricky to find out what it was, after searching the internet i checked the fuses, sure enough a 15a fuse had blown, about 6th from the right as you look at the fuse box with an engine symbol identifyng it. changed the fuse cleared the fault code job done, it seems a broken egr throttle body will blow this fuse according to my research. hope this helps someone.

code P0488 exhaust gas recirculation closed valve pintle error ( EGR Valve ) most likely replace the valve.

code P0496 evaporative emission system continuous purge flow. could be many things, Gas cap, purge valve , purge canister, probably need to have this one check by the dealer.

2005 Chevy Suburban 5.3L . getting P0488 code / Evaporative Emission Control System vent Control circuit shorted. What does that mean? How do I fix it?

i work at GM and we replace the vent vavles alot,along with evap canister and filter. but mostly due to dirt and mud sucking up into the filter .the filter is located left side of transmission by cross member,unless its been relocated already.evap canister is located at the front of gas tank or rear of it ,vent vavle is close to it .it is connected to evap canister with a tube or pipe witch ever you would like to call it. check evap for dirt or dust could be clogged.
