2004 Kia Optima won't complete emissions readiness to pass NC inspection.
2004 Kia Optima 2.7 V6 Automatic 103,700 miles I just bought a 2004 Kia Optima. I haven't taken it to get inspected because when I scanned it, it shows no codes but there are 2 emissions tests that are not showing ready. The first is the Evap purge test and the second is the o2 sensor heater test. I have driven the car over 160 miles and these 2 will not complete and no trouble codes will set. I have used the following procedure several times: NOTE: The ignition key must not be on prior to the cold start otherwise the heated oxygen sensor diagnostic may not run. 1. As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. OBDII checks oxygen sensor heatercircuits, air pump and EVAP purge. 2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks for ignition misfire, fuel trim and canister purge. 3. Hold at a steady state speed of 55 mph for three minutes. OBDII monitors EGR, air pump, O2 sensors and canister purge. 4. Decelerate (coast down) to 20 mph without braking or depressing the clutch. OBDII checks EGR and purge functions. 5. Accelerate back to 55 to 60 mph at half throttle. OBDII checks misfire, fueltrim and purge again. 6. Hold at a steady speed of 55 to 60 mph for five minutes. OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions. 7. Decelerate (coast down) to a stop without braking. OBDII makes a final check of EGR and canister purge. According to the original owner the battery was replaced less than a month before I bought the car. They had not driven the car much since that time. The car is recently off warranty and had lots of maintenance performed including new battery, new tires, new spark plugs & wires, oil change, all filters, trans flush, coolant flush, all belts and water pump. All work was performed at the dealership. The car had around 80 miles on it since all this was done. The car runs great and seems to be fully functional. I just can't get it inspected. Any help or advice is much appreciated.
