p0106, p0101, p0103 after cam install... Looks like a couple people are having the same problems as me. I installed a 228/230 .573 .571 112lsa Extreme RPM Comp Cam in my car and at first it threw these three codes...I had it tuned and now it just throws p0106, but the performance isn't nearly what it should be. Im not sure what is wrong. Me nor the person tuning the car noticed anything strange from the sensors, but it is still thorwing this code. Any ideas? We are thinking the cam might be a tooth off.

Re: p0106, p0101, p0103 after cam install... DTC P0101 Mass Air Flow (MAF) Sensor Performance
DTC P0103 Mass Air Flow (MAF) Sensor Circuit High Frequency
DTC P0106 Manifold Absolute Pressure (MAP) System Performance
Check hoses for leaks / blockage and check the MAP sensor.
This can also be a result of MAP and MAF Sensor Voltage - 5 Volts to Sensors not there, so check there first. I recently worked on a Chevy Truck with the same problem and it ended up being a blown fuse labeled 'eng 1'. So check the fuse blocks in the engine compartment.

Re: p0106, p0101, p0103 after cam install... I am having the same problem. I just had heads and a bigger cam installed. It threw out P0106 and P0101. The car is also surging forward when I have it in drive but am not giving it any gas. My mechanic cannot see me until 10/21 but I want to try to get the car track ready before then. I am losing alot of power also. Any help would be greatly appreciated.

Re: p0106, p0101, p0103 after cam install... if it's surging forward sounds like a vacuum leak?
Make sure all the hoses are connected correctly, make sure the MAP sensor is plugged in (plug on back of intake). How are your LTRIMs? Are they all over the place or maxing out?

Re: p0106, p0101, p0103 after cam install... I would put a multimeter on the plugs for the MAF and the MAP sensor. You should have 5 volt reference, a ground, and 12 volt positive through both of those plugs.
Just eliminate the possibility of a voltage issue, trust me one that one.
Sounds dumb, but make sure you didn't forget to plug that MAP sensor in, happens to everyone.
Also, monitor the MAP sensor with a scanner with the car in the on position. A chiltons will be able to tell you what it should be reading for your altitude in the country.
