Error codes
Have had the car in for a diagnostic this morning and its come back with the below error codes
P0222 - Throttle valve module poss sensor 2 signal too low
P0122 - Throttle valve module poss sensor 1 signal too low
P2135 - Throttle valve module poss sensor 1/2 implausible ratio
P2127 - Accelerator pedal sensor position sensor 2 signal too low
P0234 - Boost pressure for exhaust gas turbocharge too high
U0120 - Unknown
P0562 - System power supply too low
P0299 - Boost pressure for exhaust gas turbo charging too low
They have been cleared off. When I then started the car, ESP System fault displayed with the yellow TC light on the dash. After a few miles, the CEL light underneath that them came on. Car seems to drive fine.
It did have a failed alternator when I bought it which I had replaced. This is the first reset its had since then.
Can anyone help me figure out if any of the codes relate to the ESP. I've heard stories from dirt in the wheel speed sensors to a four figure bill for an ABS pump. The garage are getting the car back next week for more work and I'd like to be forearmed with knowledge about what it could be and cost.
Cheers
Matt

If it was me, I would start with pulling the codes from the ABS/ESP system.
That will prevent a lot of guessing and probably save time and money.
It sounds to me like this garage is not up for the job.
If they had the right diagnostic equipment there would be a description for the U0120 code. If they had enough knowledge and again the right equipment they would have pulled the codes from the ABS system right away.

As above, needs the faults reading from ESP/ABS.
Usually it's the brake pressure sensor fault on them (as per all vehicles with MK60 ABS/ESP) Fords, VW and BMW all get the same fault. New ABS/ESP unit from Ford is £1400 + vat , they can be repaired by ECU repairers such as BBA reman.
U codes are faults over the communications network of the vehicle, at a guess it will be 'invalid data received from PCM > ABS/ESP' or something like that. (if there's a fault on ABS/ESP it may give that code as the PCM is getting invalid data from it)

It went to the Ford dealer today and they checked it over. The MAF had been unplugged. Once back in, up the road and all the codes cleared. It seems fine. Now I have to sort an overboosting problem out and a small leak onto the oil cooler, but its definitely running better.
Don't get why the MAF being unplugged would have caused an ESP system fault, but I'm no mechanic, just pleased its better.

It's because the engine ECU sends data to the ABS/ESP (and back to ECU from ABS/ESP) via the can-bus communication network. MAF readings are used by the ECU to calculate engine load, this info will be sent to the ABS/ESP module.
And vice versa.
MAF may have been unplugged if someone thought it was faulty, usual test if a MAF is suspect is to unplug to see if performance improves, but on modern vehicles this can put a fault in other systems as you've found out.
£165 for a MAF from DreamScience http://www.dreamscience-automotive.c...maf-sensor.php

Weirdly though, with the MAF unplugged, it ran like a bag of spanners. Acceleration reduced on the dash.
I'll bear it in mind.
The plan is to fix the thing so its running properly and then it goes to Mountune.

Has it had a new battery? I have seen issues over on the STOC where members have had either a knackered battery or have fitted the wrong battery (not a silver calcium type), this can cause all sorts of random ECU faults.
Ask Jay on here, think he also had the same problems.

Hello everyone sorry if I go off topic, I own a FORD FIESTA purchased in 2010, a few days ago I came out the word ENGINE DAMAGE - REPAIR IMMEDIATELY.
I did a scan with FORD SCAN and to the problem, I found the following errors:
P0299 - Insufficient turbocharging
P1305 - low voltage signal due to false calibration EGR
P0299 - Insufficient Charge pressure turbocharger
by opinion of some experts it might be? How can I solve it? To force FORD?
The error I cameras and speed limits me to 100km / h.
