Failed Smog Test
 

2004 Toyota Tacoma Prerunner has an incomplete catalyst monitor.

My 2004 pre-runner has an incomplete catalyst (Catalytic Converter) monitor. Can it still pass the smog test?

Answer:  

If your Toyota Tacoma only has one incomplete monitor it can pass the smog check. However in this specific case since the incomplete monitor is the Catalyst monitor it can only pass the smog check if the monitor is incomplete for a reason other then a previous emissions problem having to do with the Catalytic Converter's efficiency. In other words, if your Toyota Tacoma was recently repaired for an emissions fault dealing with the CAT such as a Catalytic Converter efficiency trouble code, then no, your Toyota must complete the readiness test cycle and set the Catalyst monitor "on" before your Tacoma can pass the smog test.
