the egr valve is underneath the air filter housing. WARNING: there are multiple things to cause the EGR system to malfunction other than the valve (BPT valve, broken vaccum hose, solenoid, clogged ports, EGR temp sensor). A good diagnosis would be worth being wrong by just replacing the valve. Trust me, I used to work for a Nissan dealer
Code P1491 Means: EGR Valve Lift Insufficient Detected EGR Valve needs to be replaced
A P0402 indicates that the PCM is seeing voltages higher than expected from the DPFE(Delta Pressure Feedback Exaust) sensor. The DPFE is the EGR position sensor. The high than expected reading could be caused by an EGR valve that is either sticking open, EGR valve that is being held open by the EGR vacuum regulator, or it could be a faulty DPFE sensor.
On a 1996 5.7 Vortec engine, vacuum lines are primarily located around the intake manifold, connecting to various components such as the brake booster, the fuel pressure regulator, and the HVAC system. You may also find vacuum lines leading to the throttle body and EGR valve. It's essential to check for any cracks or disconnections in these lines, as they can affect engine performance. A vacuum diagram specific to your vehicle can typically be found under the hood or in the service manual for reference.
ECP fault code 0441 in a diesel generator (DG set) typically indicates an issue related to the exhaust gas recirculation (EGR) system or emissions control system. This code may suggest a malfunction in the EGR valve, sensor errors, or issues with the associated wiring and connectors. It is crucial to diagnose the underlying problem promptly to ensure optimal engine performance and compliance with emissions standards. Consulting the manufacturer's manual or a qualified technician is recommended for accurate troubleshooting and resolution.
Make sure you check the EGR valve, mine went bad and it gave me a multiple cylinder misfire code... It means it is misfiring on more than one cylinder. A new set of plugs and or plug wires may fix the problem. But it can also be many other things. Vacuum leak, fuel injector problem, etc ALSO coil packs can give you a code for multiple random misfires
