DTC P0106: Manifold Absolute Pressure (MAP) Sensor Performance

---------- Post added at 12:59 PM ---------- Previous post was at 12:58 PM ----------

DTC P0107: Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage

---------- Post added at 12:59 PM ---------- Previous post was at 12:59 PM ----------

DTC P0452: Fuel Tank Pressure (FTP) Sensor Circuit Low Voltage

---------- Post added at 01:01 PM ---------- Previous post was at 12:59 PM ----------

DTC P0641: 5-Volt Reference 1 Circuit

---------- Post added at 01:02 PM ---------- Previous post was at 01:01 PM ----------

DTC P0651: 5-Volt Reference 2 Circuit

---------- Post added at 01:10 PM ---------- Previous post was at 01:02 PM ----------

So what this is telling us is that something is shorting out the 5 volt regulated supply. It isn't bad enough or close enough to the underhood fuseblock to pop the fuse. So that means there is a long run of wire in between the faulty sensor and the power source. Since MAP sensor is getting low voltage reading this would mean it is after the MAP. My guess your fuel pressure sensor in the evap canister has shorted out. Disconnect it and clear the codes. Take your Cobalt for a test drive, when check engine comes on read the codes. If your 5V reference voltage codes are gone and you only have a fuel pressure sensor open circuit, I'm right and you need a fuel pressure sensor. If not I'm wrong and you have eliminated the fuel pressure sensor. It is the last one on the 5Volts supply and the furthest from the MAP.

Part number for fuel pressure sensor is 12223069 or 16238399. I think one is a replacement number for the other.

The stalling while in drive and coming to a stop is a different problem. You will need to clean your throttle body or get it cleaned.

Turns out there was a broken wire leading to the ecm that was causing all the codes and problems. Thanks to everyone that helped direct me to an answer.
