First problem I ever has with my Camry was having the battery die and replacing it. Now, my car stalls while driving. I quickly put it in neutral, turn the key, and restart it with no problem. I've seen threads regarding the computer having to relearn, but I drove for a week or so after changing the battery without a problem. Think the comp wouldve reset in that time so its gotta be something else. The check engine and traction control lights are on, so got the codes read. I just replaced the master flow sensor. Still stalling. Not sure where to go from here.

 

What were the codes?

 

Printout reads:

PO171 System too Lean (bank 1)
PO607 Control Module Performance
PO171 System too Lean (bank 1)
PO101 Mass Air Flow Circuit Performance
PO171 System too Lean (bank 1)

 

Describe the stalling issues.

Are the battery connections good?

P0607 is the ECM which can be difficult to diagnose. Low voltage to ECM can cause this code.

P0171 is lean fuel ratio. Vacuum leak, intake/exhaust leak, bad A/F sensor (bank 1 sensor 1), MAF sensor, PCV issues, ECM.

The Traction light on is normal when the check light is on.

 

It just stalls as Im driving. Not so much a problem when Im slowing down to a stop or when Im accelerating but when Im just crusing along the rpms will suddenly drop and it stalls. Ive even let it sit at idle in the driveway for 10-15 mins with no problem. When it does stall, I just put it in neutral and start it right back up. Starts back real easy.

 

You take a guess and look at the Bank 1 Sensor 1 A/F sensor which the P0171 refers to.

The P0607 can be challenging to diagnose DIY.
