VLT Record #: Your vehicle's record on the Bureau of Automotive Repair's Vehicle Lookup Table (VLT). The table contains specific information for each vehicle model and engine combination available. Information from the VLT regarding your vehicle's weight and aerodynamic resistance allows the Smog Check emissions analyzer to correctly set the resistance on the dynamometer (a treadmill-like device used to test vehicles in the smoggiest urban areas of the state).

All CA owners should browse this site. There is lots of good information, and since many of our cars have been tagged as "high emitter profile" everyone needs to get educated and understand how to manage your test.

The VLT # for my car is 10038 and the the test weight is 3250. I'd still like to see your VLT # to verify if they did ID your car incorrectly. Do you recall that they scanned in the VIN from the renewal form? Did they get the VIN correct or mess up the engine code?

Thanks for posting the data. I suspect the cat was not fully warmed up during the 2000 test. My first test, two-speed idle test, in '91 at 39K miles was very good, but the second test in '93 (at 49K) idle HC went from 9 PPM to 76, 99 (1 PPM under the limit) in '95 and continues to be high ever since including my ASM tests (especially at 15 MPG), which began in 97.

It's interesting that my car has low NOx and yours is high. I never understood why they went to EGR in '89, and I have verified that the '89 camshaft is the same as '88, so they didn't reduce overlap. (More overlap increases exhaust gas residual, which acts like an "internal" EGR system.)
