EGR System .....Not Ready

I had a similar problem with my Chevy Malibu! NEW BATTERY = FAIL SMOG TEST in California!

I needed to 'freeway drive' as much as possible for four days before the computer would 'reset'... THEN it passed 100%

Hi howard lee
Did you disconnect the battery some time before the smog test? Did the smog inspector say he got a "system not ready", EGR testing not complete? If so drive it for another week or so and retest it.

can be a bad cat /sensor / computer or wiring usually takes about a 100 to 125 miles on most vehicles to reset after clearing a code dead battery or replacing battery but thats if all systems are working properly if it was reset because of a code and that part of system hasnt reset than more than likely a problem with a component or system from original code

Whatever lot you bought the car from they should be able to tell you what happen. in that case you should take the car to a high tech mechanic who will probably be better to assist you

The system has to see a wide range of conditions before a smog test can be done. On most brands you have to drive at least 50 miles, at various speeds including stop and go, let it idle for 5 - 10 minutes, and run at freeway speed for at least 25 miles. It also has to reach normal operating temp of 195 degrees.

Have the charging system tested, it sounds like the battery went dead on you from a charging system failure. Charge the battery up enough to get to a local Autozone, Sam's club or O'reilly auto parts for the testing, it is free .

In order to set the monitor it the drive cycle 2 trip criteria that means you need to have a cold start up and reach operating temperature then another cold start up with a operating temperature reached and the drive for each one is part throttle hold for 2 miles and a decelration for the catalytic to get ready.when the cat is ready the evap runs.If you are loosing monitor at key off and everything reset you can see the referee let them smog it. The EGR and EVAP are almost impossilbe to get ready

Yep ,sounds like limp mode ,should be in second gear.
Try,key on engine off,depress accelerator to floor 3 times within 5 seconds.Should reset trans.

It could take more driving always make sure you have between 1/4 -3/4 tank or monitors cant run has anyone checked to make sure the EGR is functioning? Not just the valve but the EGR system?

I replaced the EGR Valve ($80 after tax), problem solved, vanruns great now. Now my problem is that I can't get the light to turn off.
