Did you clear the codes after the SAP was reinstalled??

If not, clear the codes, this will also clear ALL the Emission Readiness Monitors as well.

The SAP Readiness Monitor should clear on the first cold start, if not, then the SAP MAF may be an issue, but we have seen pumps with the impeller slipping on the shaft, relays with too much Voltage drop and Kombi valves that stick.

 

I didn't clear the codes. I usually avoid clearing codes as it seems if I can fix the problem the car will always eventually clear them itself as problems are corrected. Maybe not always?

Codes will clear on the own, but can often take 20-40 run cycles.

Clear the code, if it does not come back, then you are good. But you need to watch the Readiness Monitors that will be required for Emission Testing.

Most states will allow 1 Readiness Monitor to not be clear, CA will allow only the Evap Readiness Monitor to be the 1 Readness Monitor to not be clear.

The Evap Readiness Monitor is the hardest to clear.

 

Will do! Texas allows any one monitor to not be set. Everything except Evap went to ready pretty quickly before so should be good hopefully.

Thank you.

:thumbup::thumbup: Good to go after this morning's cold start up. Thanks.

 

Hopefully you can get all the other Monitors to Clear/Ready status quickly before a possible return of an error.

Here are MY suggestions for getting most of the Readiness Monitors to Clear/Ready state quickly.

1. Start engine cold from sitting overnight and allow the engine to idle normally for 2 minutes, 10 seconds.
2. Accelerate to 20-30 MPH and maintain steady speed for 3 1/2 minutes.
3. Accelerate to 40-50 MPH and maintain a steady speed for 15 minutes. A good car only needs 3-5 miles if the O2 sensors are working properly.
4. Before shutting engine down, allow it to idle in gear for approximately 5 minutes.
The diagnostic routine shown above will be discontinued whenever:
• Engine speed exceeds 3000 RPM
• Large fluctuations in throttle angle
• Road speed exceeds 60 MPH
NOTES:
Try to have the fuel tank filled betwee 3/4 & 7/8 of a tank. Often you will need at least 2 Run Cycles to complete most of the Readiness Monitors. The Evap Monitor is the hardest to clear, however, most states allow 1 Readiness Monitor to not be clear, CA now will allow the Evap Monitor to not be clear for SMOG testing.

Just updated my other thread. Everything is set to ready. Your drive cycle is boss! I got most everything set last night on a ten minute drive then the SAP and Evap set this morning after cold start and drive to work. [emoji2]

Get to the inspection station before something sneaks up on you!!!

Glad you are getting close to the finish line!

No doubt! My temp permit expires today so hopefully I can get over there and knock it out before they close.

 

Old thread but my P2430 encounter could help others.

I had a single P2430 code that kept tripping the check engine warning. SAP pump was OK. Took a chance and ordered a new secondary air MAF. For once, first try fixed the problem.
