Question SLK230 With CAM Sensor Code

1998 SLK230 with 61,000 miles: CEL with codes P0341 (CAM POS Sensor Range/Performance) & P0410 (Secondary Air Injection Sys Malfunction).

Car is slow to accelerate and tends to bog down on up-hills without down shifting appropriately. Have reset code and returns at varying intervals (intermittent).

Have not found the smoking gun yet. Troubleshooting so far includes: No loose connections, vacuum lines okay, clean MAF, and clean throttle body.

CAM Position Sensor shows 8 ohms resistance both cold and hot. With key ON, voltage is 12 volts & 7 volts at the plug connectors (each wire).

Should my next step be to change the CAM POS Sensor?

Default Problem solved.

Replaced the Cam Pos Sensor ($140) and all codes vanished. After 2 weeks- no repeat.
