Please help! Audi a4 2.0t trouble
 

I recently aquired an audi a4 2.0t with 120,000 miles. I was told it was misfiring and just needed a camshaft position sensor. Check engine light and EPC light are on. I ran a scan and have these error codes:
p2014 intake manifold runner sensor
p0190 fuel rail pressure sensor
p0118 engine coolant temp sensor
p0113 intake air temp sensor
p0343 cps a circuit high input b1

I did just put a new camshaft position sensor, no change. I read a forum where a guy had same error codes and it was a bad ground from the ECU. Not sure if ive checked all possible grounds. Any direction or advice would be much appreciated. Thank You!
