Inspection (emissions) failed. What to do?

That doesn't always happen.

Many states test emissions. Many query the OBD system records, AND test emissions.

An inoperative MIL is itself cause to fail the test, but the cluster will have to be pulled to replace the lamp before the test is repeated. And a code is a starting point, not a diagnosis.

That may be the charge for the state-mandated test, which is performed on a $35,000-$50,000 machine. The machine also has significant maintenance costs, which can easily be hundreds of dollars per month. Many shops lose money on these programs - but the consumer won't care about that.

Most dealerships set this charge high to discourage walk-in traffic. They just need to be able to test their used-car inventory.

That depends on the cost of the component at time of manufacture. Some are covered, some aren't.

An odd explanation. It sounds more likely that - rather than something "electrical" being wrong with the "OBD", one of the on-board monitors - periodic diagnostic self-tests, which are executed via software - had not yet run. My guess would be either the EVAP monitor or the catalyst monitor.

It's rare for Toyotas to have a problem running monitors. For other makes, it's quite common.

 

Don't the mode $06 monitors have to at least show "complete" for an
emissions check to be valid? Or is some of that data translated
into mode $01 PIDs for the sake of the mandated OBDII stuff? If
you've got a good reference or two on how all this plays out, I
wouldn't mind brushing up..

The OP has a 2002 Prius, which is rated as SULEV and has an 8-year/100,000-mile battery/emissions warranty. The 10-year/150,000-mile warranty is for the AT-PZEV Gen II Prius.
