My car has just had a new Air Flow Meter and Lambda Sensor ( )and the garage are having problems clearing the ECU. They think that maybe as the car was driven for so long with these problems (back from France), the codes have become "engrained" in the ECU

Any suggestions on how to get rid of them?? Disconnecting the battery has been tried as has the plug connections/ acclerator situ.

Any novel ideas?? They are waiting on an email from Japan...

PS STi5 BTW...

have to use a select moniter then but i've never heard of fault codes being engrained in the memory.

Codes are still there 'cos the fault's still there, methinks The codes are stored in a memory that *will* lose it if you reset the ecu - if they're still there, they're new. All imho of course, I'm no mechanic....

I don't think the faults are still there... if it was that simple I am sure it would have been sorted!

Scoobyboy, what the heck is a Select Monitor

Richard is right Kingsize,

I have found that a lot of people assume that just because they have replaced a component that the fault is cured which is not always true.Is/was the check engine light coming on?Have the garage actually checked the wiring from the sensors and to the ecu?
It may even be a ecu fault(never seen one yet on a scoob)but there is always a first time.
Do they know how to clear the faults without the diagnostic tool(Select Monitor)

If I can help mail me

Not a STi but on my MY01 I had fault codes which pointed at different items, these were then changed. The problems persisted until they changed PPP ecu, so ECU can go wrong even though select monitor always gave other faults. See if dealer will do a temporary swap to see what happens.
Hope this helps

Steve/ Tezza,

Thanks for your input on this. I will talk to the garage today to see what if anything is happening and suggest what you have mentioned...

I just want the car back... I returned with in from France on the 3rd March...

PS Cheers for the suggestion Richard!! Guess you may be right

The KAM (keep alive memory) should be wiped when the reset connectors are attached. If not the next thing i`d check is the wiring of the replaced sensors. Failing that an ECU swap to see if the fault code still appears. Diagnostics sucks time wise, but with a logical / metodical approach the fault will be found
Are the codes relating to the replaced sensors ?

Pete,

I have spoken to the garage and they are very much on top of it, although as you say, diagnostics is a time eater... The ECU has been reset, and the codes dissappeared (select monitor job) only for them to reappear after a 5 min test drive [img]images/smilies/mad.gif[/img]

I am not sure whether the fault codes relate to the replaced sensors though. If they had another STi5 ECU down there they would swap to see if that is causing the problem but as they don't, I beleive emails are going back and forth to Japan in an attempt to find out the problem. I gather my car is the first STi5 to cause them this much grief.

Just my luck

I've got exactly the same fault with my 1996 STi2.
Select monitor was plugged in at Scoobysport.
02 sensor fault came up.
Changed the Lambda still coming up after a reset and 9% CO.
Had the car in a Bosch agent for 48 hrs,all sensors working okay,even swapped the MAF with another car,still didnt cure it.
Still 9% CO and check engine light coming on down the motorway!!!
They believe there is an ECU fault,need to swap one over soon where i'll be close to a exhaust gas analizer????????

Cheers

And our cars are suppossed to be soo reliable... I know that it is reasonable to expect some grief with any car you own (especially a performance car), but in the 5 months I have owned it, it has been in the garage for well over a month. And I treat it with the utmost respect!

Honest

Still, nowhere near as much grief as Dad's GTV
