What does the p2238 OBD-II trouble code mean?
What does the p2238 OBD-II trouble code mean?
What the P2238 code means? P2238 is an OBD-II generic code for the engine control module (ECM) detecting the O2 sensor for bank 1 sensor 1 has a short circuit for the heater control circuit of the O2 sensor. What causes the P2238 code?
What does stored code p2238 in PCM mean?
A stored code P2238 means that the powertrain control module (PCM) has detected a positive current discrepancy in the upstream oxygen (O2) sensor for engine bank number one. Bank one is the engine bank that contains the number one cylinder.
What does the ho2s code p0031 mean?
P0031 is the code for HO2S Heater Control Circuit Low (Bank 1 Sensor 1) What the P0031 code means P0031 code means for the engine to run correctly, the engine exhaust must have a specific air-fuel ratio of 14.7 to 1 as signaled by the heated oxygen sensors (HO2S) which detect the oxygen content of the vehicle exhaust.
What to do if your p2238 O2 sensor is reset?
Unplug the HO2S in question and use the DVOM to check resistance between the positive current control circuit and any ground circuits. If there is continuity, suspect a defective HO2S. If the code P2238 continues to be reset, start the engine. Allow it to reach normal operating temperature and idle (with the transmission in neutral or park).

What does it mean when your OBD-II scanner says p0031?
If your OBD-II scanner indicates an error code P0031, this means that you have an issue with your O2 sensor number one. For many vehicles, this is also known as an air/fuel ratio sensor. Here are a few steps to help you our if you’re wondering, “How do I fix trouble code P0031?”
