P1103 fault Code
Hi Guys

Hooked the caravan onto the back of the 110 today (2009 utility) and after a long pull up an incline on a dual carrigeway. got a MIL on the dashboard.

Have a scanguage 2 which produced the fault code P 1103 - which was fine. However, the scanguage will not let me reset/clear the code which is strange. Any ideas? Question

Truck was just serviced last week, so everything is as it should be (i hope....) Rolling Eyes

Wouldn't normally be bothered, but I'm pulling the van from Aberdeen down to Silverstone after work today, and would prefer not to do the trip on the back of a RAC recovery truck if at all possible! Rolling with laughter

Thanks in anticipation.......[/b]

Might be worth picking up a spare MAF en route for peace of mind

Thanks for that - good advice.

Just rang the local stealer who happens to have one in stock - but is wanting £119 for it!!

I've seen other posts with them around the £30 mark.....think I'll keep looking.

cheers

I just cleaned my MAF sensor (done it every 25,000 km) - massive improvement. You must use proper MAF cleaner though (not carb or MAP etc.) or you can strip the coating. See

Worth a try before binning it perhaps? Tell someone you love them today because life is short.
But shout it at them in German because life is also terrifying and confusing...

P1103 is a 'nuisance code' that will invariably reset after a few driving cycles. If it persists then look at a MAF but at your stage I wouldn't be overly concerned. Numerous threads about it if you do a search under 'P1103.'

A Mass Air Flow fault will throw up a MIL light and drive perfectly well! It is usually accompanied with a P1103 code if you have a reader! It states Mass Air Flow either high or low but still within limits! In this instance the MIL light will extinguish after a few driving cycles and the fault will be logged in your ECU! Nothing to worry about as it is effectively a nuisance fault!


Thumbs Up If you go through life with your head in the sand....all people will see is an ar5e!!

Treat every day as if it is your last....one day you will be right!!

I get this code P1103 when cruising on motorways perhaps with high acceleration. I have closed my egr mechanically ie. Closed inlet and outlet of egr. Don't know something to do with it. When this occur, I simply use the scanguage. I always clear the code when dash lights illuminated at ignition but with engine shut downed. I noticed when engine is on the scanguage does not response to clear p1103.

A previous post on clearing fault codes with a Scangauge 2 2007 (57) Defender 90 (Sold)
Looking for another to replace it.

The road less travelled.... is a muddy one!
