How to read EGR delete module fault 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):-

Why is my PWM card not working properly?

A failure of the mechanical motion system or servodriver The connection of the analog connectors of the PWM card failed. A circuit on the servodriver detected errors on some internal supply voltages. The voltage to the servodrivers is too high. The voltage to the servodrivers is too low. The servodriver temperature is too high.

Why is the EGR valve on my Navara stuck?

Mechanical fault. The EGR valve is stuck open or is jamming (due to carbon build up or possibly a bent shaft). Mechanical fault. Solenoid circuit malfunction.

How to reset the engine control module with no hassle?

Disconnect the battery and Switch the ignition key to the on position for about 15 minutes should reset the ECU Can a ECU be reset? Yes, all ECU (Engine Control units) can be reset and be should reset once per manufacturer’s guideline for a smooth relearn process or upon installing a replacement unit. How do I reset my Ford PCM?

What causes a failure code on an EGR system?

Another common problem causing failure codes in this system is that the tip of the valve will become irregular shaped from carbon deposits. When this happens it no longer creates a perfect seal. This can allow exhaust gas to continue to flow when not called for by the computer. An example would be at engine idle or when the vehicle is cold.

What happens when the EGR valve gets stuck on a GM 4.3L?

This tutorial addresses a very common problem I’ve seen on the 1987-1995 GM 4.3L, 5.0L, and 5.7L engines with throttle body fuel injection system: a stuck open EGR valve. And when the EGR valve gets stuck open, it’ll cause a rough idle condition that may hard to diagnose.

What to do if your EGR monitor is not running?

Start with making sure your vehicle has no known EGR monitor setting issues identified by the BAR and CARB, and next get in to hands-on diagnosis of what is causing the monitor to either not run or not complete. Since the check engine light is not on, we can be confident the ECU has not found any specific emission component failure.

Where can I buy a Delco EGR valve?

Won’t pass the state mandated emission test. You can find the EGR valve in any auto parts store. If you’re wanting the buy the original AC Delco (Delphi) EGR valve, you can buy it online for a whole lot cheaper than somewhere local. The following links will help you comparison shop for the AC Delco and after market EGR valves:
