P2270 O2 Sensor Signal Stuck Lean B1S2

The P2270 is a fairly straight forward code pointing to a fault in the downstream heated oxygen sensor (B1S2). Basically, it's not switching in the alotted time that on-board computer needs to see. Carefully inspect the wire harness and electrical connector for any loose, broken, pinched or rubbed through wires. Make sure there are no current exhaust leaks in the system. If the visual inspection checks ok, replacing the sensor should solve the problem.Bank 1 is on the passenger side and sensor 2 is by the cataytic convertor.

Hi Paul, Have you had a fault code relating to the knock sensor? That sensor controls ignition timing which can have a relationship to the fault codes you report? Regards John

Auto Zone can scan for free. There is a lot of sensors that can triger a fault code.

According to my book, it looks like a bad O2 sensor, the sensor behind the catalytic converter on the passenger side exhaust.

Bank 1, Sensor 2.

You can pick one up at the parts store for around $75.

The code is printed on a sticker in the glove box

Check owners manual, made written on inside of covers or on radio pages.  IF not check inside of glovebox for four digit code.  If not luck, remove radio document all number, ie serial number on unit and call local honda dealer.  They must run the VIN and radio info back to the motherland to get lock code.
