What does p2237 O2 sensor positive current mean?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain. A stored code P2237 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 causes the p2237 OBD-II trouble code?
All our repairs are backed by our 12-month / 12,000-mile warranty. P2237 is an OBD-II generic code for the engine control module (ECM) detecting the O2 sensor for bank 1 sensor 1 and has an open circuit for the heater control circuit of the O2 sensor. The ECM tests the sensor circuit after the engine is warmed up. What causes the P2237 code?
What is the DTC code for O2 sensor?
P2237 is a diagnostic trouble code (DTC) for “O2 Sensor Positive Current Control Circuit/Open Bank 1 Sensor 1”.
Which is p2238 sensor positive current control circuit low bank 1?
So the codes that ive been getting is p2238 (current control circuit low bank 1 sensor 1) and p2241 (pumping current circuit low (for a/f sonsor) bank 2 sensor 1) and so ive replaced the o2 sensors like this wiki said and there doesnt seem to be anything wrong with the electrical and the engine runs…
