EGR Fault Codes - Will the EGR delete module override a fault code? Posted on 8 Jun 22:37 , 0 comments
In addition to achieving its purpose of deleting your EGR, the Crisp Mods EGR Delete Modules can also remove certain Engine Codes.
In order for the EGR Delete Modules to work, they require a complete electrical circuit for everything to read as normal to the ECU.
Here is a list of the most common Engine Codes that relate to the EGR (all codes need to be read by a OBD2 Scanner):-
|
Fault Code |
Reason |
Cause |
Will the EGR Delete Module Solve this issue? |
|
P0401 |
EGR Flow Insufficient Detected
|
This code will come up with a blanking plate or the EGR is stuck closed. Mechanical fault. |
Yes - Not all models, for further information please call us. |
|
P0402 |
EGR Flow Excessive Detected |
The EGR valve is stuck open or is jamming (due to carbon build up or possibly a bent shaft). Mechanical fault. |
No |
|
P0403 |
EGR Circuit Malfunction |
Solenoid circuit malfunction. ECU reads voltage low at EGR solenoid. Electronic fault |
No |
|
P0404 |
Exhaust Gas Recirculation Circuit Range/Performance |
Solenoid circuit malfunction. ECU reads voltage high at EGR solenoid. Electronic fault |
No |
|
P0405 |
EGR Sensor A Circuit Low |
The position sensor for the solenoid is malfunctioning. The sensor is reading that the EGR is closed more than it should be based off the readings. Electronic fault |
No |
|
P0406 |
EGR Sensor A Circuit High |
The position sensor for the solenoid is malfunctioning. The sensor is reading that the EGR is open more than it should be based off the readings. Electronic fault |
No |
|
P0407 |
EGR Sensor B Circuit Low |
The position sensor for the solenoid is malfunctioning. The sensor is reading that the EGR is closed more than it should be based off the readings. Electronic fault |
No |
|
P0408 |
EGR Sensor B Circuit High |
The position sensor for the solenoid is malfunctioning. The sensor is reading that the EGR is open more than it should be based off the readings. Electronic fault |
No |
|
P1404 |
IAT - B Circuit Malfunction/ EGR Closed Position Performance |
The system is reading that the EGR is possibly stuck open. Solenoid issue. Electronic fault |
No |
I strongly recommend that, if you do not already own one, you buy a OBD2 Scanner. My personal preference is the Ultra Gauge. Even if you are running a stock vehicle, these scanners are really handy to have as it will cost you around $25.00 minimum each time you need a mechanic to read a code for you.
If you have any issues or questions, please do not hesitate to give me a call or shoot me an email. I’m always happy to help.
