Multiple Fault Codes from OBDII Scan

[tomwazza]

Hi All,

Any help would be greatly appreciated...

I've got today and tomorrow off work because I was planning to rectify a couple of MOT advisories on my 197. I've got one tyre that's near legal limit and 'play in steering rack inner joints'. I was planning to fit the new tie rods and TRE's today, then pop down to the garage for the alignment and to have the new set of tyres fitted (they are all different makes etc, so I thought a set would be better) tomorrow.

Got everything ready, but was just going to head into town to get some degreaser and some gloves. 5 minutes into my trip and the engine warning light starts to flash, the ESP light is on, as well as the traction control light and the maintenance spanner. The car seemed to be OK but I was only driving quite slowly and couldn't tell if it went into 'limp mode'.

Anyway, I pull over and turn everything off and have a quick google on my phone, and decided to fire it back up again to drive home. All the lights had cleared and it seemed to be driving OK. I got home plugged in my OBDII scanner and got quite a significant list of error codes:-

Error Code	Description	Comments
P0300	Random/Multiple Cylinder Misfire detected	Quick search on here says possibly Lambda, but could be anything?
P0503	Vehicle Speed Sensor Intermittent/Erratic/High	Not Sure, dodgy speed sensor?
C1203	ABS Outlet Valve Coil Rear Circuit Open	Not Sure
U1F03	None	Google showed nothing
U1B03	None	Google showed nothing
U1B03	None	Google showed nothing
U03DB	None	Google showed nothing

My question is, has anybody experienced any of these, and if so what was the resolution?

Also, should I clear the codes and see what appears again?

Any help/advise would be greatly appreciated.

Thanks,

Tom.

Hi mate is it still on the light ? U codes are usually communication codes between modules. Maybe ckp sensor or plugs/ coil pack ?

After pulling over, I started the car up again and drove home without any warning lights at all.

make a note of them and clear the faults as some of them could from ages ago

use/drive as normal until it has another fit and then see what the codes are

the p0300 is a code the engine doesn't know whats causing the fault so it puts this one up

Thanks buddy, yeh I thought it'd be a good idea to clear the codes.

Just took it for a long drive and not had any issues at all, plus it's tracking quite well considering the work carried out this afternoon.

Had the alignment done and everything went well except the rear camber is out on the near side. Will probably end up buying one of these to correct it:-

A 1 degree shim should bring it back into tolerance.

Edit :- also since wiping the codes I've not had any problems, will update soon.
