Code P114d?

EML came on today, after reading the OBD with Torque Pro there is a single code of P114D. Can't find anything conclusive online. Any ideas?
 
It's usually something triggered by the O2/lambda sensors.

In my case (when it started throwing the codes up on last year's National in the Lakes) they were fine (which is amazing considering they're the originals) and it was a dodgy MAF.
 
Yea..

Manufacturer specific code....

Dont quote me on it,bur think its a generic increased emission fault code....

Suspect MAF or Lambda's..... have a look at live data and see if MAF has correct airflow and Lambda's are switching at correct rate and not "locked" in lean/rich mode.
 
Can I do that using Torque or need something better. Some software for my laptop would be better. How do I see the live data?
 
It depends on what diag machine you use as to how to access live data..

i have never used torque app,so cant help you with that..

OK I only have the app on my phone to read my OBD data. I guess I need something better to read live data. Any affordable recommendations? I have seen INPA kits with a USB to OBDII cable. I would like to be able to get as much info as possible really.
 
With torque you can clear the code and light. Worth a shot as this happened to Taz in France. Not come back since.

He was caused because he put super unleaded in where as he normally only runs standard unleaded.

When I clear the code do I have the engine running or off and just have the ignition on? Is there a set procedure for code clearing?

Was your code the same?

can you recall what my error code was?
 
Right I have cleared the code with torque. Taken the car for a 30 min run and can't feel anything obviously wrong. I will see if it reoccurs. Thanks for the support gents.
 
Try giving the MAF a clean....

The MAF and the Lambda sensor operation go into long term fuel trim fault code tables... They can twig up in months or many miles,never immediately as the car checks drive cycle operation and will only twig the fault if it consistently reappears over a period of time/miles

I would still get your INPA sorted and look in live data,check lambda and MAF operation....

Say for example a lambda is stuck in rich operation,the DME tries hard to compensate and will to a certain extent... But too much fuel is being pushed into the catalyst.... Again the cat will convert the gasses as much as it can,until its worn out..

Non of this will be felt when driving,the car is very good at shrouding problems...

So £30 of lead and software may just save a few quid in the long run..

Thanks for this info it's really helpful!
I have bought a £27 cable and INPA software on ebay today. Once it arrives I will defo check out the function and see what is going on. Will it be obvious if there is a problem or do I have to know what to look for in the data?

Oem paper air filter or aftermarket K&N style crap?

Huh?
(The car has an eventuri intake.)

As stated above, try clean the airmassmeter if the filter isn't the dry sort.
Dunno about the Eventuri, but if it uses the oiled (K&N style) filter it will eventually lead to dirty AFM, and wrong readings.

I got a similar fault code this summer, suspected the same issue & sure enough - there must have been some sort of 'sport filter' earlier as the AFM was proper greasy.

Just reset the ignition and spray lots of electronic cleaner on the meter, letting it dry before reattachment.
