The best way to get these to set is drive the car at 35 miles an hour for 7 miles. At this sped the egr is more likely to operate and set the monitors.

When driving, do i just drive in stop and go traffic, do i brake or do I just drive at a steady pace and hope for the best?

Customer: replied 1 month ago.
Had the transmission rebuilt and need to smog the vehicle and it failed on the evap & egr. I did get the evap to reset but still having an issue on resetting the eve.

Need to reset the egr, I misspelled the last word.
Expert:  Roy replied 1 month ago.

ok good

the way I set them is to accelerate from a dead stop to 40 mph. you cannot hit the brakes or it will cancel the test. do this 3 times and re check the monitor.

the procedure the previous tech gave was good as well but you need constant speed at 55 mph for at least 10 minutes without touching the brakes.

Customer: replied 1 month ago.
the car sat for a long time on my property and the battery died and the vehicle did need a transmission based on the mechanic that rebuilt it,
Expert:  Roy replied 1 month ago.

ok, I would take it to your guy and have him check the egr system. the fact it will not set tells me there is a problem with the egr system.


Customer: replied 1 month ago.
Already did that!

Customer: replied 1 month ago.
The egr system is fine!
Expert:  Roy replied 1 month ago.

if he checked it correctly, he should have done them monitor set as a verification. common practice in diagnostics.

I guess he did not verify it.
