Throttle accentuation issue vs. MAF sensor issue
#16
Your right, it's MAF B.. But this is a British car, not an American. Bank A is always the drivers side......but doesn't change for a region of sale. So Bank B or MAF B would be on the left side being it was built in Britain.
Easiest way to know is by looking at the engine, the head that is the most forward is bank 1...so the right side on your car is bank 1
The throttle code is a safety code..when the fault of the MAF is excessive, it restricts the throttle, which triggers the throttle dtc..

Thanks for your response irish07. I will order another MAF monday and change the left side.
Before going through changing the part - I just want to double check. Would a faulty left sided MAF cause the car to throw p010a and p010f? I'm not entirely sure what p010f means.

p010f is set for all rationality failures and so is automatically set when p010a is set.
The PCM airflow estimate comes from a 2D table if MAF has failed(FMEM) or from a correction of a predictive airflow 3D table that is called "Load with Failed MAF Table" in Ford parlance.
p0106 is set when the estimated manifold pressure is more than 3.9 psi different from the measured manifold pressure and you guessed it, the estimated manifold pressure comes from linear equations based on tables of Cam advance, RPM and MAF airflow!
p2106 is set when one of the critical input sensors for the electronic throttle doesn't make sense.
So, one bad MAF can cause all those codes. Go Irish!

Ladies and Gents!! The EECVI God has spoken!! I could swear Ford has you on speed dial! LOL

So I just had the Driver side MAF Replaced. When doing so, I found that the d/s air box was very mangled up. There are two large cracks in it/on one side a chunk looks like it broke off. I had the MAF replaced and the air box put back in place for now.
Took it out for a drive - and it drove perfect…but the check engine light came back on.
The same series of codes came up once again!
p010a, p010f, p0106, p2106
I'm not sure if the cracked air box is the culprit. The filter inside is of course fit snug and in good shape. The air box alone is just damaged. Would the air box trigger these codes to come up?
If not, I don't know what else to do at this point. I have changed both MAF's and cleaned the throttle body good enough to eat off of.

I have read through the forum and have seen people running K&N filters without an air box…and have seen people with "swiss cheese air boxes" (drilling holes through their air boxes.

https://www.6speedonline.com/forums/...ns-please.html
I wouldn't personally do this - for fear of hydrolock, but how are these systems running without throwing any codes - and I am throwing multiple codes with a cracked air box? Is it because there is unequal flow between the two sides?
I'm wondering if there is any way to test this out prior to replacing the air box. If the code is resulting from unequal flow, would temporarily removing both air boxes be a viable method of testing to see if this is the culprit?

I'm wondering how the heck the airbox got cracked in the first place? The only way to get to it is either through the bumper or bottom plate. That doesn't look like the plastic just started getting brittle or rotting. Previous owner have some unreported damage?

I will definitely be changing my air box - but I am just wondering how having a crack in the box would be causing these codes.

If you take off 1 filter put a high flow awesome unit, and leave the other stick filter with an airbox that has restriction....the MAF's won't be balanced. The ecu can accept unbalance of air when turning or wind gusts. But for a long period of time the ecu will start to think there is a blockage or a MAF faulty. Being the Ecu doesn't diagnose physical impact/damage, the ecu will flag the sensor as not reading correctly.
So you have 1 box split open allowing a less restrictive flow of air vs a sealed box that is more restricted on the other site..righr now the MAF sensors are not balanced... Is this an issue? That's what datalogging would be used for, to see how much grams are being monitored and if there's any glitches.
Being that box was hit, I would inspect the wiring and even the pins in the connector yo make sure none are lose(pin drag test) and allow check the wiring for any pitches or cuts. The harness is tight around the MAF so it very possible the wiring could be chuffed/cut/stretched/ inside the wiring insulation when the box was impact Ted and moved. You can test through this by doing a voltage drop and/or resistance and amerage check.

I took both air boxes off and the car is driving perfectly. Thanks for all of you help iris07,
rmrmd1956, and jdoubleu.
I'm in the process of ordering a new d/s airbox.
I found two parts but am unsure which one I need - awaiting an email from the parts department at Ambits
http://astonmartinbits.com/models/5-V8-Vantage/parts/1217
This part reads "AIR FILTER HOUSING AIRBOX LEFT" unsure if this include the plastic piece of the box that I have cracked..
The other item: http://astonmartinbits.com/models/5-V8-Vantage/parts/404
Not exactly sure what the difference is - but I'm glad I finally have the problem resolved

The difference is that the first one is the standard airbox. The second one has solenoids and flaps that open up at a certain point to let in additional airflow - it's from the "Aston Martin Power Pack"/V8 Vantage S/V8 Vantage GT.
