First I am attaching a somewhat short log of the car running at idle with it warmed up.

Ok so I pulled my fp red to send it in for a rebuild. Zero issue with the car when I took it off. It set during the waiting period for 3-4weeks. I get the turbo in the mail a week or so again and slap it on. Since this time I continue to see p0107 constantly. I can not figure this problem out and it is extremely frustrating.

First I took the map and maf sensors off and cleaned them to no avail. I have since replaced the map sensor itself. It is a Omni 4 bar which ive read do fail some so I thought that would be the culprit. This did not help with. I confirmed there is a good ground at the connector and 5 volts reference with the key on. I checked for a boost leak last week but will do so again this afternoon along with change the plugs because why not. As seen in the log the fuel trims are way off, the afr is crazy lean etc.

The tune itself was spot on before the rebuild and so was the car I only did the rebuild because the turbo was shot and smoking out the exhaust. That issue is fixed but now I have one which I cant drive the car.

I cant see any way the turbo thing would cause this or relate but its also very coincidental. No other codes have shown up but this one have came back at least 6 times. Any help would be appreciated very much.

 

I dont think the omni and stock.map will have the same baro resdings. Maybe its tripping it out.

Have you checked if you can disable that code from returning in ecuflash periphery?

 

The tune file is scaled with the proper values for the Omni. It had an Omni before this was an issue thus I thought it was faulty and replaced with a new Omni.

 

No boost leaks worth mentioning are present.

 

Swap map sensor

 

The code is for voltage low on the circuit. So, its either a bad electrical connection, or another bad sensor (not too likely). Check to make sure the connector is fully pushed on the sensor, make sure all the pins are pushed all the way in the connector. Check the harness for issues with the wires.

 

I tested the connector and found a good ground at the connector as well as 5 volts reference with the key on.

 

You need to check the output of the sensor. The signal going back to the ECU is what is low, not the 5v reference going to the sensor.


You can check it at the sensor, then check it at the ECU to see if there is a discrepancy.

 

What ^ said. I just had the same issue. Replaced sensor and golden!
