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 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 are the possible causes of a p2238 Toyota?
P2238 TOYOTA Possible Causes 1 Faulty EFI Relay 2 Faulty Air/Fuel Sensor Bank 1 3 Air/Fuel Sensor Bank 1 harness is open or shorted 4 Air/Fuel Sensor Bank 1 circuit poor electrical connection 5 Faulty Engine Control Module (ECM)

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.
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…
