New car - need to clear some faults
 

Hi guys
I've just bought a 2012 SS model, the 100k service has been completed before the sale but there are a few minor fault codes that I need to clear.
I have one of those Bluetooth OBD2 devices and downloaded the chevvy app and have discovered the following fault codes:-

P0422 - Evaporative Emission Control System Leak Detected Small Leak
P0522 - Engine Oil Pressure Sensor/Switch Circuit Low Voltage (this may be the reason the oil pressure gauge doesn't work, but operates when the engine is switched on)

There's also a Service airbag warning light on the dash and heads up display which shouldn't be an issue, but the OBD doesn't pick up this fault code.

Just so that I can go into the garage prepared, would anyone be able to help me out with part names and/or numbers please?


Thanks in advance

Monty
