Lambda & cam speed sensors

Had a little problem with D2 which on diagnostics showed up as 14 faults, all as the result of a blown secondary air injection pipe. we replaced the pipe (eventually) and the mass air thing as that was obviously faulty. she starts and runs fine now but is still showing faults on all Lambda Sensors and the Cam Speed Sensor.

It has been suggested to take the old girl for a good run and we'll probably find the faults will clear, what do you think.

And could the original problem have damaged those parts.

Cheers

Perhaps the faults will go away but they the indications are not self resetting and there's a need for the system to be pluged into a Testbook or similar to clear them.
