I've been far to busy working instead of enjoying retirement, and haven't had time to go Jeeping in months. Unfortunately, I let the Jeep's battery go dead, but I recharged it so I could take it in for a smog test. It failed, and the smog test equipment said it was because the Jeep's computer was unable to complete three emission control tests... Evap, O2 sensors and O2 sensor heater.
When the smog guy learned that the battery had been dead, he explained that, when the computer sensed power again (when I recharged it) it needed time to test the emission control systems. The short drive from our house to the testing facility, apparently wasn't enough time. He said I should drive it around for a day or so, then bring it back. By then, it should have had time to complete the tests. He was right (mostly.) The Evap and O2 sensors were fine, but the O2 sensor heater test still says the test hasn't been completed.
I've probably put 75 miles on the thing - freeways, residential streets etc, but the smog test equipment still says the O2 sensor heater test hasn't been completed. One more thing - I've never gotten a Check Engine light, and my OBD II rear says there are no active or pending codes. Any idea how long it should take (time/miles) for the O2 sensor heater test to be completed?
