I installed x-charger on my 2007 mustang
It's good I really like it~!
but after pop up trouble code..
p0301,p0108,p0403,p0405,p0406
p0301 code are off and on intermittently..
other things are still have..
any body know that?

First, you did install the Xcharger tune, correct?

----------------------------------------------------
P0301 - Misfire Detection Monitor

The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause.

Ignition system
Fuel injectors
Running out of fuel
EVAP canister purge valve
Fuel pressure
Evaporative emission system
Base engine

The MIL will blink once per second when a misfire is detected severe enough to cause catalyst damage. If the MIL is on steady state, due to a misfire, this will indicate the threshold for emissions was exceeded and cause the vehicle to fail an inspection and maintenance tailpipe test.
------------------------------------------------
Misfire could be that you have the spark plug wires on wrong. When you do an Xcharger it is easy to mix up the wires going from the coil to the spark plugs.


-------------------------
P0108 - BARO/MAP Sensor High Voltage Detected

Sensor operating voltage is greater than 5.0 volts (VREF), as a result it failed above maximum allowable calibrated parameter.
VREF shorted to VWPR
BARO/MAP signal shorted to VPWR
Damaged BARO/MAP sensor
Damaged PCM
VREF should be less than 6.0 volts. PID reading is in frequency/Volts
----------
Double check your connections, especially each one that you have to cut and splice to extend wires.

-----------------------------------------------------------

P0403 EEGR Electric Motor Windings Or Circuits To The PCM Shorted Or Open (Vehicles with Electric EGR)

The EEGR system is continously monitored to check the 4 EEGR motor coils, circuits, and the PCM for opens, shorts to power and ground. If a malfunction is detected the EEGR system will be disabled and additional monitoring will be suspended for the remainder of the drive until the next drive cycle.
EEGR motor windings open
Connector to EEGR not seated
Open circuit in harness from PCM to EEGR
Open circuit in PCM
Short circuit in EEGR motor
Short circuit in harness from PCM to EEGR
Short circuit in PCM
If an intermittent condition is suspected the most effective methoid of wiring fault isolation is to use the wiggle test methoid while measuring for shorts and open circuits.

P0403 - EGR Vacuum Regulator Solenoid Circuit Malfunction (Vehicles with out Electric EGR)

This test checks the electrical function of the EGRVR solenoid. The test fails when the EGRVR circuit voltage is either too high or too low when compared to the expected voltage range. The EGR system must be enabled for the test to be completed.
EGRVR circuit open
VPWR open to EGRVR solenoid
EGRVR circuit short to VPWR or GND
Damaged EGRVR solenoid
Damaged PCM
The EGR vacuum regulator solenoid resistance is from 26 to 40 ohms.

P0405 - DPF EGR Sensor Circuit Low Voltage Detected
See DTC P1400

P0406 - DPF EGR Sensor Circuit High Voltage Detected
See DTC P1401

P1400 - DPF EGR Sensor Circuit Low Voltage Detected
The EGR monitor checks the DPF EGR sensor signal to the PCM for low voltage. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value.
DPFEGR circuit short to GND
Damaged DPF EGR sensor
VREF short to GND
Damaged PCM
A DPF EGR PID reading less than 0.2 volt with the key ON and engine OFF or running, indicates a hard fault.

P1401 - DPF EGR Sensor Circuit High Voltage Detected
The EGR monitor checks the DPF EGR sensor signal to the PCM for high voltage. The test fails when the average voltage to the PCM goes to a voltage greater than the maximum calibrated value.
DPF EGR circuit open
VREF short to PWR
Damaged DPF EGR sensor
DPFEGR circuit short to PWR
SIG RTN circuit open
Damaged PCM
A DPF EGR PID reading greater than 4.5 volts with the key ON and engine OFF or running, indicates a hard fault.
--------------------
Did you get the EGR valve and tube seated correctly when you reassembled? Double check that component.


Check your connections to the throttle body as well. If you didn't mark the connectors as you removed things it is easy to switch two of the connectors and get fault codes.

thanks a million !!!!! for your detail reply!!
step by step I'll check everything.. My local carshop will help me..
it's seems not easy problem.. also I need study a lot
after that I'll change pulley to 2.8" (now 3.0")

JimC

When you go to the 2.8" pulley you will need an updated tune. You will be pushing more boost and the tune needs to be updated to account for that.
