The EGR (Exhaust Gas Recirculation) light is alerting you to inspect and service the EGR system. The light is triggered by the odometer, not the system, so after it is checked and serviced, you'll need to reset it under the dash board.
To reset the EGR light on a 1987 Subaru GL Wagon, you typically need to disconnect the battery for a few minutes to clear the engine control module (ECM) memory. Alternatively, you can use an OBD-I scanner to clear any error codes related to the EGR system. Ensure that any underlying issues are resolved before resetting the light to avoid it coming back on. Always refer to the vehicle's service manual for specific procedures.
Maybe it's not closing all the way? I have a 96 roadmaster wagon and have been getting check engine light lately - code error is EGR related P0400. Found out there is service bulletin for corrosion problems with the valve.
it usually means the the EGR valve needs to be replaced. If your car is "bucking" on start up then for sure it is the EGR valve.
Mine did this and come to find out it needed a EGR valve. manifold caused this to come on.
Code 12 is a faulty EGR valve. You need to clean or replace the EGR valve of all carbon. The exhaust passage on which the EGR is mounted needs to be cleaned of carbon deposit as well. The flashing D4 light indicates a transmission problem. This needs to be looked at by a professional.
Just because a code that is titled to a particular system is noted does not mean that component is bad. Check the passageway.
If vacuum hose to EGR is ok, then valve may need to be replaced, or passages cleaned out.
The EGR valve is sticking open You can remove and try to clean it but most likely you will have to change it. Cleaning rarely works. The code description is EGR pintle position error
I's a problem with the EGR system and or the EGR solenoid.

The check engine light code P0401 on an Acura indicates a problem with the Exhaust Gas Recirculation (EGR) system, specifically that insufficient EGR flow has been detected. This could be due to a clogged EGR valve, a malfunctioning EGR system, or issues with related components such as hoses or sensors. Addressing this code typically involves inspecting and cleaning the EGR system and ensuring all components are functioning properly. Ignoring this issue can lead to decreased engine performance and increased emissions.
