How do I fix error code P2238?
What repairs can fix the P2238 code?
- Replace the O2 sensor for an short circuit in the heater circuit.
- Repair the wiring connector or wiring to the O2 sensor for shorts.
- Replace the power relay for the heater circuit due to a burned out or shorted circuit that the pinpoint test indicated.
What are the symptoms of a p2238 trouble code?
Symptoms of a P2238 trouble code may include: Reduction in fuel efficiency Diminished engine performance Stored misfire codes or lean/rich exhaust codes Service engine soon lamp illumination What are some of the common causes of the code?
What does p2238 mean on an O2 sensor?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain. 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 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 happens if oxygen sensor is not connected?
If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine’s timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.
What does the code mean on a Toyota p2238?
Because the heat of the heater is conducted through the alumina to zirconia (of the sensor portion), sensor activation is accelerated. The code is output when there is an open or short in the A/F sensor circuit, or if A/F sensor output drops.
What causes O2 sensor positive current code p2238?
Code P2238 is caused most commonly from an internal failure of the heater circuit inside the O2 sensor.
What to do if the p2238 code is reset?
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). Connect the scanner to the vehicle diagnostic port and observe oxygen sensor input data on the data stream.
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…
