P0349 Fault on 2004 Porsche Cayenne S: Sensor Replacement Not Resolving Issue

Model: 2004 Porsche Cayenne S Fault Code: P0349 Posted: 2018-08-10 16:11

I'm experiencing a P0349 fault on my 2004 Porsche Cayenne S (US model), indicating a cam position sensor issue. I followed advice from Renntech and Rennlist, which recommended replacing the sensor. I replaced the bank #2 (driver's side) cam position sensor, but the code persists. The wiring harness and connector appear intact with no visible damage or corrosion. The vehicle drives normally—no power loss, smooth idle, reliable starts, and consistent fuel consumption. Given that the car is a 2004 Porsche Cayenne S, I'm seeking further insights into potential causes beyond sensor replacement. Are there any other diagnostic steps or underlying issues to consider? Thanks for your help.
