Engine not running properly, codes 41 and 42?

Hello,

the codes:

41 - Camshaft sensor circuit fault, ignition control circuit fault

42 - Electronic spark timing (EST) circuit grounded

I would start with the ignition module replacement; Also, I would replace the coils which cause the module to go out. this is common with these cars here is the location of the module and how to change it out in the images below. Check out the images (below). Please let us know what happens.
