EGR valve????

Hi,
How long can I keep driving w/ my check engine light on (caused by EGR
valve) on a 1998 honda prelude??? Is the EGR valve that important??? any
assistance would be tremendously appreciated...
thanx in advance...

 

not very long. pull the code and determine the exact problem. if
you've already done that, post the code along with your
question!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

yes, it regulates emissions and reduces combustion temperature. that in
turn reduces oil consumption & extends the life of "hot" components like
exhaust valves.

 

Hi,
I'm not sure what the code exactly looks like... but the guy at Autozone
gave me a ticket that reads, "Wells... EGR4045... O.E.M. #18011-P13-00"
Does this mean that I have to change the entire valve or just the
gasket???
thanx again...

 

What engine?
Some 2.2 Honda's clog the passages and cause egr problems, not a big fix and
cheap too.

You're going to have to be more careful in your reportage. That code is
invalid.

-----------------------
Valid standard EGR codes:

P0401 Exhaust Gas Recirculation (EGR) Insufficient Flow

P0404 Exhaust Gas Recirculation (EGR) Control Circuit Range/Performance
Problem

P0406 Exhaust Gas Recirculation (EGR) Valve Position Sensor Circuit High
Voltage
----------------------
Valid enhanced EGR codes:

P1491 Exhaust Gas Recirculation (EGR) Valve Insufficient Lift

P1498 Exhaust Gas Recirculation (EGR) Valve Position Sensor Circuit High
Voltage

P2413 Exhaust Gas Recirculation (EGR) System Range/Performance Problem

 

Hi,
Sorry about that... I believe the code is "P0401"... should I replace
it or should I clean it??? Is the latter pretty simple to do or should I
just go to a mechanic???
thanx again...

 

EGR is important.

it is emission related so if your EGR not working right than i think
your car will not run right.

EGR sents the exhaust gas back to the combustion chamber to reduce nox.
