Check Engine Light Diagnosis PO715 and PO400
Hey All
I have had my CEL on for a while and had the free diagnositc from AutoZone tell me the codes are
PO 715- Input/ Turbine Speed Sensor (A Circuit) and
PO 400- EGR Flow Malfunction
I have had no obvious issues with the operation and running of my car, but would like to get these sorted out. I own a 1995 850 GLT nonturbo. If any one else has had these problems and knows what needs to be done to correct please let me know.
Thanks a lot for your time and advise!
Regards!

Is the check engine light on now? Sometimes old codes from a one time glitch are stored and once reset, they do not come back. Reset the codes and then see if they (and the check engine light) come back.
