Check engine Light P0131 & P0132

I have a 2002 MDX and have a Check engine Light P0131 & P0132 codes.

I replaced both O2 sensors, upstream and down stream, and that did not fix the problem.

I also replaced the fuel pressure regulator after reading some post and agin nothing.

Any Ideas?????

Thanks, Bruce

Before you do anything else, take it to an Acura dealer and have the ECU re-flashed. Explain you want it re-learned, re-flashed, reloaded with a fresh load of Firmware EVEN IF THE VERSION IS THE CURRENT ONE!!. This may or may not help your issue, but just like the OS on a Personal Computer, firmware gets corrupted. My 2005 TL lost 50% of its power when the outside air temperature went above 80 deg F. For years we couldnot solve the issue....many new sensors later, on a whim, I had my dealer re-flash the ECU. Now in temps above 95 deg F., my TL still has full power. It NEVER falters any more......285,000 miles on the car....love my TL. Dealership mechanics, anymore, are 'part changers', they are NOT troubleshooters.
