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.
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…
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.
How much does it cost to repair a p2238 Toyota engine?
The cost of diagnosing the P2238 TOYOTA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. The Air-Fuel ratio (A/F) sensor provides output voltage approximately equal to the existing air-fuel ratio.
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 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?
