Sorry, I'm still not sure what you mean with the 2 leads. You're not talking about the pins for the connector are you? If so there are 3 of them.Was thinking - unplug it from the car. The sensor has two leads, connect those meter leads to the sensor and set it too Ohms. Likely 0 - 500 or so and apply vacuum. Its looking for pressure drop to tell the ECM the EGR valves commanded action actually took place.
So does it still have both codes and how far have you driven it? What are you using for a code reader and what does said reader display for "Readiness"
The only thing I have up and running is a phone app Torque Pro.
The last code was a P1487 only, I cleared it today and I'll be putting about 100 miles on the car today and tomorrow. Maybe I'll get lucky and the light won't come back on.
When I had emissions tested last week I had 3 unready conditions, and I'm only allowed to have 1 unready condition and no CEL in order to pass.
Thanks again for the help.
