smog testing issues
 

2000 Boxster S, approximately 34,000 miles and I’m having problems passing CA smog.

A few months ago I had a MIL showing the P1128 and P1130 trouble codes which cleared with a code reader.

Last week the testing center revealed P1128 and P1130 trouble codes are now classified as passive (no MIL light) and that the catalyst monitoring system was not complete.

I cleaned the MAF, drove more than 200 freeway miles one morning and took it to the testing center. Now it’s throwing evaporative system and secondary air systems not complete errors’ the P codes are gone as is the catalyst monitoring issue.

Any insight helping to address these issues is appreciated.

Looking at the Drive Cycle restoration sequence offers little hope since I live in an urban area with stop signs and lights at every corner.

The 2000-2001 cars often took well over 200 miles to reset everything to a ready state for emissions, assuming what ever caused them in the first place were correctly repaired.

Thanks for the insight!

When the weather cooperates I'll put some more miles on it and report back when it clears.

My car failed at the smog test too first when I had only about 50 miles in it after a complete rebuilt and 13 years sitting. I drove 300 miles and then it passed. But, if your problem with the SAI or EVAP system persists it won`t pass.

I just managed to clear the two "not complete" issues.
The SAI problem was fixed by starting the car cold with the headlights and AC on and running
it to 2,800 rpm for 90 seconds.

I just managed to put 350 miles on the car and the EVAP problem "evaporated".

Thanks for all the help!

Where in SD are you?

Where in Palm Springs are you?

I'm in La Mesa...

Bad weather in Sun Diego ! I've never heard of such! :cool:

The HOT part!

I have a vacation home near Vista Chino and Landau

I'm in RB, but moving to Austin in 45 days

Well actually it was raining at the time I was working on the issues...outdoors in my driveway. No rain now though and it's supposed to be 71 this afternoon.
I've lived in Toronto, Denver, Syracuse and DC so I understand what changes real weather can bring...

Enjoy your time in Austin..a great town.

I grew up in DC and lived in Dallas for year.

Yea, the weather just sucks in San Diego

Easiest job in the world is being a weather forecaster in San Diego...
You could be locked in a windowless closet and forecast 72 deg and sunny and be correct 85% of the time

My '01 Boxster sat in my driveway for two years during the height of the pandemic. I finally got offf my ass and decided to get it going again.Drained the old gas and oil, changed the plugs, replaced the tires, replaced the starter motor- the issue that initially sidelined the Boxster. The car starts up and runs beautifully. The big unsolved issue is resetting the monitors. Four show ready, four do not. I'm aware of the process to reset them but I'm in San Diego- so driving for the times indicated for the reset will be impossible with all the lights and stop signs in any path I choose. Also driving between 40 and 60 on the freeway seems risky and certain to get a stop. Somewhere I read a post that claimed to have done it by just using the engine in neutral and maintaining the rpm's in the correct range. Anybody tried it successfully? finally, can anyone with SanDiego experience suggest a route to try resetting the monitors
