Honda S2000 P2272:  B2S2 O2 Sensor – Stuck Lean

P2272 in the Honda S2000 is a general diagnostic trouble code.  It means that the “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture.   This does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t).  P2272 is typically … Read more

Honda S2000 P2270: Symptoms, Causes, + Diagnosis

P2270 is a general DTC trouble code, which means it has the same meaning for the Honda S2000 as it would any other vehicle.  It means that the oxygen sensor located on bank 1 behind the catalytic converter is continuously sending voltage that indicates a lean air/fuel mixture.   This does not necessarily mean that … Read more

Honda S2000:  P1009- VTC Stuck Advanced

P1009 is a common Honda made vehicle trouble code.  This code indicates the VVT advance control is malfunctioning, leaving the engine timing stuck advanced. Many Honda S2000’s use something called a VTC actuator to control the camshaft timing of the engine.  It works by using oil pressure to hydraulically move the camshaft.  This allows the … Read more

Honda S2000 P1399:  Random Cylinder Misfire

P1399 is a Honda specific diagnostic trouble code.  It means that more than one of your S2000’s cylinders is misfiring (maybe just one, more on that below), and is most common fix is to adjust the valve lash or replace the bad ignition component. P1399 Quick Facts Most commonly caused by valves that are out … Read more

Honda S2000 P0453: Fuel Tank Pressure Sensor/Switch Too High

Your Honda S2000 utilizes an evaporative emissions control (EVAP) system to migrate fuel vapors from the gas tank and fuel filler neck, and sends them to the engine to be burned off.  When the pressure inside of the fuel tank is too high, P0453, is thrown and the check engine light comes on. If the only … Read more
