P1172 Honda Acura or P2A00
Fix code P1172, P2A00 – Honda 2005-08
If you have a check engine light and either of these two trouble codes P1172 Honda, P2A00 Honda, P1172 Acura, P2A00 Acura on the vehicles shown below, this might be your fix.
Honda has issued a TSB to correct a problem where high moisture content present in the exhaust on warm startup may damage the air/fuel sensor 1.
P1172 – air/fuel sensor 1 circuit out of range
P2A00 air/fuel sensor 1 circuit range/performance problem
Honda has come up with a software fix and a new air/fuel sensor to correct the problem. Do NOT simply change the air/fuel sensor for an aftermarket product. Get the newer Honda part and pay a shop to install updated software to prevent further damage.
