You need a repair shop to drive the vehicle with a professional
scan tool, for at least 25 miles

That way all the Emissions Monitors will run clear

If you fail to do that,your guaranteed to fail inspection

If any codes come back,then the vehicle has to be component
test & repaired

It sounds as though there was some pushing & poking, done by
I assume, a shop & parts changed,tested or in need of replacing,
who knows

You also will have freeze frame data at the time the codes are set,
to help with the diagnoses,IF-- you have a good shop to work on it,
so far that doesn't appear to be the case

I don't buy your hopeful rational --IF-- the oil has not been changed
(often)over the life of the motor,wrong oil used or the cam actuators
have failed,as is sort of where all this conversation has gone or
explained to you

If the cam timing is not correct,then yes, the oxygen sensor codes
may set- BUT- I don't buy the fact they go away & never come back

We could be here a long time,so I suggest you keep your line of
questions going at a repair shop. Their not wrong or far off,you just
need to understand how things work together in a motor or maybe
not play well with other parts under certain conditions

2004 porsche cayenne i reset computer and now it will not start


Clearing Codes, clears all data, then all the emission
monitors have to run again, or you won't be excepted
to inspection

Clearing codes & data,has nothing to do with diagnosing
why you got the fault codes & fixing the problems

How would clearing a dash light help pass inspection?

Before you got down the street two houses, the light would
be back,the car has a failed system ,thus the light on the
dash after the motor is started.

You cleared all data,now a shop can't even work on it
You removed all vehicle history & codes

Flat bed it to a shop & they will make the repairs you neglected
to do, while trying to get hundred miles before the parameters
on a failed system went out of range & the dash light came back

Need to study OBD 2 Systems on the internet & leave the vehicle
work to the pros

Failed emissions test


First step is to have the code or codes read.If the "check engine light" is on there will be a reason and should be a code or codes to be read.Once you have the codes,you can determine the correction needed to get that "check engine light" out and a valid emissions test completed.Get back to us with the codes found.

Check engine light is on service codes p2231 p1418 are active . 2004 bmw 325i m56 engine


Hi,

The code you reported does not seem to have relevance for BMW. Often generic OBDII codes do not have meaning and in this case the fault code does not correlate with any reference tables that I am using at this time. If you can have the car scanned with the BMW proprietary software and revert with those codes, it might shed light on this issue.

Let me know.so that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

first of all. clear the codes in the fault memory then drive it again. and check for new codes. if it is o2 sensor again then it could be many things other than the sensor. what you have to understand is that the car is making the decision of what it thinks is wrong. and the final thing in the whole process is the exhaust gas. if its wrong then the sensor will pick it up. it might well be the sensors at the current mileage, but dont rule out the obvious. air leaks on the intake system (EGR). etc. miss fires. the list goes on... hope this helps..

My check engine light came on it said P2626


This is an O2 sensor failure with the sensor located in the manifold. The associated heater probably failed causing the sensor to fail.

Emission Failed Inspection. Engine light not on.


I've always found the following to help with emissions tests on older cars: Check & replace air cleaner if dirty (difficult to see light through it), Check spark plugs ( will also be good indicator of any bad cylinder so keep them in order of removal) - if any look/measure bad, replace the set. Check engine oil quality & replace if dirty (or you can't remember the last  time it was changed). Dirty oil = higher emissions.
Run engine on higher grade fuel for a few days and during test (better fuel = lower emissions). If o2 sensor is the problem it will set off codes.
