What does the p2270 code on a Chevy mean?
P2270 CHEVROLET Meaning The Powertrain Control Module (PCM) supplies a voltage of about 450 mV between the HO2S high and low signal circuits. The oxygen sensor varies the voltage over a range from about 1,000 mV when the exhaust is rich, down through about 10 mV when the exhaust is lean.
What does the p2270 code on the O2 sensor mean?
What the P2270 code means. P2270 is an OBD-II generic code for the O2 sensor signal stuck lean on bank 1 sensor 2 to the engine control module (ECM). This means that the O2 sensor in bank 1 sensor 2 indicates either too much oxygen in the exhaust stream, an open circuit, or a defective sensor which causes a lean signal to the ECM.
When to set the DTC on a p2270?
When the signal from the O2 sensor is detected by the PCM as being stuck lean or biased lean, this DTC is set. The P2270 DTC refers to downstream sensor (after the catalytic converter), sensor #2 on bank #1. Bank #1 is the side of the engine that contains cylinder #1.
Which is Bank 1 of the p2270 code?
The “bank 1” portion of the P2270 code refers to the side of the engine that contains cylinder #1. Its counterpart is P2271, which affects the sensor on the other side (bank 2).

What is the p2270 trouble code for bank 2?
Please try again later. This P2270 trouble code refers to the post-catalytic converter O2 (oxygen) sensor on bank #1, sensor #2. This post-cat sensor is used for monitoring the efficiency of the catalytic converter. https://www.facebook.com/pages/Bullsh… Loading…
