Engine Management Light


I'm new to the forum so forgive me if this has been asked and answered before.

I have the orange engine symbol showing on my dash. I assume this is an engine management light and it is warning me about something. This is the third occurrence of it showing in the last 6 months.

The last time it appeared I had it turned off by clearing all the fault codes. I should have noted what the fault codes were before they were cleared. The light stayed off for about a week or so but it is now back on again. This time I noted the fault codes before they were cleared and the EML is now out.

The codes shown are -
P2636-08 Fuel level sensors H2 Plausible
P0460-07 Tank level sensor circuit High Input
U0073-00 Unknown DTC
U0073-00 Unknown DTC
P2453-08 Particulate Filter pressure sensor Range/Performance

The car does have problems with the fuel level sensors thus giving obscure readings at times but tell me an Antara that doesn't. The first time the EML came on it was suggested that I take the car for a long drive keeping the engine revs over 3000 RPM which I did so along the motorway for about 30 miles each way. This did not immediately put the light out as it was not until the next day that the EML went out during normal city driving.

I have had a look through the forum and found others talking about this light and automatic transmission. My vehicle is manual 4wd so I assume this does not apply.

Any help with this matter would be gratefully appreciated.

Yesterday I decided to Google the P2453 fault code and I came up with a YouTube video
which explained one of the reasons why one would get a P2453 fault.

I took my Antara to my friends garage and he checked the hoses mentioned in the video and found that the hose had perished. I was not prepared to pay 216 for a new set of pipes especially when it was only a 200mm length of tube that was perished. My friend suggested that we could replace it with a length of Oxy/Acetylene tube. The problem is that the old tube is 'Z' shaped and if one tries to bend Oxy/Acetylene tube it will kink enough to prevent the flow of gases. I thought if the pipe was spiralled it will not kink and should give a free flow of gases along the tube. We spiralled the tube and connected it to the steel pipes and it appears to be working properly with no kinks.

I took the car for a run yesterday evening and checked the fault codes when I got back to find the P2453 fault was no longer there. I will wait for about a week or so and recheck the codes and the new tubing to see if all is well.
