Let me start off by saying thank you to Natzee for reading the copes on my car today... much appreciated!!

So the 2 codes that came up are above. i have read previous threads and realize I may have a MAF sensor issue. Nat and I took off the air filter cover, and low and behold the filter was very dirty... very embarrassed I haven't changed it :cursing: Anyway, I'm replacing that ASAP. I was hoping anyone could also tell me what the code meant; are there more problems? I have been hearing my starter grind every 10 start-ups... maybe its going out? Any suggestions??

Thanks in advance,

The computer thinks the smog pump system is not working properly, but the pump itself can be fine. There is a very long list of things to check. One of the many is the air flow sensor.

The easy thing for you to check is if the air pump comes on in the morning when the car is cold. That is the turbine like sound you hear when you first start the car. I can hear it with the top up. Or you can listen near the vent on the passenger side since the electric air pump is right above the vent in the engine compartment. Or better yet, remove the engine lid and start the car when it is stone cold then look at the pump to see if it is running. This is easy for a dealer to do since they can turn it on with the PST2.

Yes, I can hear the air pump turn on in the morning. Is there a way to check the sensor? Is it possible the light was triggered due to a dirty air filter? The car is running great... Thanks!

Yes, thank you. Is the sensor the cause for both codes? I'm getting the new filter on Monday. I'll clean everything, as mentioned in your email, including the sensor then and hopefully the light will not re-appear.

It is not going to be the filter. You need to come to a work on cars day. Every filter we remove has all kinds of crap on the black foam and there is no check engine light related to the filter condition.

We tap it on the ground and all the junks come out. If the place we are using has an air compressor then we blast it with air.

I'll be there for the next one; are they posted on the calender? Any recommendations on where to order the sensor from or is it just a dealer pickup? Thanks once again!
