MAF Sensor Fault Code??
Happy Friday everyone,

Just fitted a Demand Engineering down pipe and full sport’s exhaust system to my 2009 2.4 TDCI (yesterday) took it for a test drive and the engine light came on with the attached fault code! could this be linked to changing (removing) the Cat??

P1103-00 (EF) Mass air flow sensor in range but higher than expected. At 0mi

I cleared the fault and it hasn’t come back on yet…… 😬

Hello Swim_Cap

I can't answer the question between a CAT Removal and if this is likely to affect the MAF Sensor...
But it is tempting to think that yours may not be just a coincidence.

I had a MIL / Warning Light at about six month intervals with a P1103 fault code when I first got my 90
(a 2010/11 2.4 tdci all Standard Mechanicals)

I bought a ScangaugeII as a consequence of this.

My fix on about the 3rd occasion was to Clean the MAF with a 'specialised' cleaner
(lots of don't use just anything for this on-line.... WD40 for example Shocked )

I do this once a year, with No reoccurrence now for 5 years.

Maybe worth a try as you watch and wait for potentially this to repeat itself.

Hello Swim_Cap

Hope this works for you… just to add from reading up a bit around the P1103 fault code on a Puma,
I think that the MIL / Engine Warning Light re-sets itself after around 6 Engine Cycles, I’ve seen variations on exactly how many and to what actually counts as an Engine Cycle (Duration / Rev Range).

My first / second P1103 did ‘self cancel’, after around a week of daily use. On plugging in the Scangauge P1103 was the recorded Fault Code, which could be Cancelled (with the ignition / not engine on).

Another ‘observation’ my local independent said to me very early on when I got my 90 to keep an eye on and swap out the Air Filter regularly… the ‘Puma likes to breathe’.

Good luck SKIP
