p-1450 fault code

I had code p-1450 set on my 2003 Discovery II and have been unable to find any information for this code. Any help would be appreciated.

Either can I . I would go back and recheck the code number. Is your truck running bad?

Thanks for the interest, funny you should ask if then rover is running bad, this is the first time in 10 years that I got 360 miles out of a tank of gas. It has always run very good and still does. I rechecked the code and it is the same.

P1450 Land Rover Leakage Detection Module failure:Signal implausible

I have no idea what it means though.

Joey, can you tell me where you found that. I again went thru 6 or 7 other fault code charts and still can't find that for a Rover, did find it for Ford's, BMW's and a few other vehicles though.

A year ago I had a code P-1453, and I found some vague description similar to this code, I removed the valve on the inside frame rail in the center of the vehicle and took it apart, there was a gasket sealer that had shrunk and the ends were not mating, also the material looked like it had come apart. I put 12 volts to the motor and it would not turn. So I took the motor out of the plastic housing and turned the shaft by hand, it seemed very hard to turn for such a small motor, so I took the impeller out of the housing and cleaned it with air flow sensor cleaner. Put it back and tested the motor again, this time you could hear a definite suction noise out of the pump, I cleaned the housing parts of old seal material and sealed it with "The Right Stuff " which is a silicone. Put the valve back on the vehicle and no more problems. I did notice that when I would gas up there was pressure in the fuel tank, which had never been there before. Now I have a P-1450, which is pretty close to P-1453, so I think I will take the valve off again and see if the impeller is stuck again. I will let you know...

Thanks Joey, that is a handy site.
I believe what they are talking about has to do with the Evap, system and not getting a good reading. I would suggest you do a search in the Rave under engine management and search out evap codes and issues.
