How long does it take for EGR to reset?

Typically driving the vehicle for 100 to 200 miles will clear the system, so you might want to have a professional mechanic take a stab at it with their equipment if it doesn't clear up in the next week or so. via

Does new EGR valve need coding?

You'd ideally need to get the codes read before buying any replacement parts. Your symptoms could be caused by your EGR valve if it has stuck in the open position, but then again there are multiple possible causes of your symptoms, some of which could involve a lot of expense. via

How do I reset my car monitor?

Start cold (below 86°F /30°C) and warm up until engine coolant temperature is at least 160° F (typically requires at least one minute; up to 3 minutes). Accelerate to 40-55 MPH at 25% throttle and maintain speed for five minutes. Decelerate without using the brake (coast down) to 20 MPH or less, then stop the vehicle. via

What does no EGR off idle test mean?

The PCM will successfully complete the EGR monitor if the proper flow of EGR is detected and no EGR flow at idle is indicated. If the flow rate detected is too low or too high or present at idle the PCM will set a pending code. via

What happens if EGR valve is stuck closed?

If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration. In a diesel engine, a bad EGR valve is one of the causes of a black smoke. The Check Engine light might also come on in either case. via

How long does it take for a car to go through a drive cycle?

Answer: Depending how old your vehicle is, the catalyst monitor might be allowed to remain incomplete and the vehicle still pass the smog inspection. Currently 1999 and older gasoline powered vehicle's are allowed one incomplete monitor. via

What RPM does EGR open?

If possible, check the movement of the valve stem at 1500 to 2000 rpm. The valve stem should move if the valve is functioning correctly. If not, and there's vacuum, there's a fault. Apply vacuum directly to the EGR valve using either a hand vacuum pump or scan tool depending on the type of EGR valve. via
