I keep getting Several fault codes on my 1998 SLK

Question

The following codes keep coming up on my 98 SLK230...do you think a new K40 will take care of them? We have replaced/cleaned most other sensors already:

P0105
P0410
P0341
P1525

Answer 1

P0105 MAP sensor circuit malfunction

P0410 Secondary air injection system malfunction

P0341 Camshaft hall - effect sensor

P1525 Adjustable camshaft timing solnenoid

With P1525 and P0341 in the code gathered here, then yes a K40 relay , there are parts of the soldering leg that fails to make proper contact.
