I have a 2009 Santa Fe with 63K miles on it and yesterday at lunch the check engine light came on - it had been fine on my morning commute a few hours earlier.

I got the diagnostic codes - 2187 and 2189 - System too lean at idle bank 1 and bank 2.

The vehicle seems fine - running smoothly, no detectable loss of acceleration or performance. I'm hoping it may be an O2 sensor which could be a reason for these codes.

I called the dealer about it - I was just there for my 60K service. They told me if I wanted to bring it in it would be $95 do do the diagnositic - hook up the computer and get the codes. I told him I had the codes, but he insisted it would be $95.

I feel like I'm being scammed, but if there is an issue I obviously want to fix it and not just ignore it. I thought the folks here might have some advice on how to proceed - thoughts?

 

A lean condition in both banks usually means a leak in the intake. Check the tube after the MAF and before the throttle body. Also look for intake manifold leaks and vacuum leaks (like a stuck open PCV).

Other problems could be a weak fuel pump (low fuel pressure) or a clogged fuel injector(s).

You SF should still be covered under the warranty of you are the original owner.

 

I was finally able to bring the Santa Fe in for service and the issue has been diagnosed as a bad MAP sensor. I was told that said MAP sensor is only under warranty until 60K - I'm at 64K now but this probably happened at or very near the 60K mark (I've been waiting for an appointment at the dealer that works for me). About $250 to fix.

Seems to me that a sensor should have more than a 60K warranty. When I had a Subaru Outback the speedometer/odometer stopped working and Subaru tried to tell me that it wasn't under warranty, but we all know your speedometer/odometer is really NEVER supposed to break so they agreed to fix it gratis.

Anyway, I was advised to call Hyundai customer care and see what they would do for me - anyone ever having any luck getting Hyundai to pick up the tab on a sensor replacement like this?

 

did you clean the MAP sensor ? i also changed the big clamp there and she runs a lot better. gotta run it for a few cycles then recheck the codes. Any progress on your end ?
