Recently changed the battery in this car and need to get it smogged. The tech at the smog center told me that changing the bettery reset thr computer and no codes are showing. He said to put around 60 miles on it and come back, which I did and the car still is not passing the computer check. How many miles does it take to get this done?
Well it is not as simple as driving the car. It must be put in the enabling criteria to run the tests So 1st make sure the gas level in the tank is between 15%-85% and the car has sat for 12 hours outside temp and coolant temp within 10 degrees of each other start and let idle for 3-5 minutes then drive the car normal no jack rabbit starts or hard accelerations bring to 45 mph run for 2 minutes coast to 20 mph do this twice then on freeway set cruise to 58-62 mph no hills or down grades drive for 10-15 miles then idle for 2 minutes. shut car off let sit for 5 minutes then repeat the 45 mph part to end again. next day rerun cold start. then have drive cycle monitors tested if all are completed then it passes smog.
150 miles at least also check ur air filter change nice clean one
SOURCE: HCL too high, did not pass smog check.
ok well this might be a hard one . from what i can gather by the co reading and the o2 reading is that we are running fat. a couple things can cearte this one how many miles do we have on this mtr, two do we have a vacuumn leak? three is the vech going into closed loop? some how we need to get are hands on a scanner so we can look at a data, other wise you are going to be throwing parts at this vech , and thats not the way to fix your problem. the odds are that you may have some lazy o2 sensors you are close. have you tryed running the vech down the road before you go in for the test. the converter is like a hot water heater you have to bring it to operating temp before it will operate correctly. keep me informed

CA you can take the car to a referree and get a one time waiver if you have spent a minimum of $450 on repairs not including smog fees. Gives you two years to get it fixed.

Here is a list of possible causes, hope this helps.
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.
