What does code P2238 mean?

Error Code P2238 is defined as O2 Sensor Positive Current Control Circuit Low Bank 1 Sensor 1. A problem usually caused by a wiring short to ground, error in HO2S wiring, short to positive, or PCM issue.

What is code P2241?

P2241 is an OBD-II generic code for the engine control module (ECM) detecting the O2 sensor for bank 2 sensor 1 has a low voltage for the heater control circuit of the O2 sensor. The ECM test the sensor circuit after the engine is warmed up.

What causes the p2241 OBD-II trouble code?

What does the O2 sensor code p2238 mean?

Code P2238 is a code indicating the O2 sensor heater circuit is shorted causing the circuit voltage control to be low. This will cause the fuel feedback control to not work and the ECM to put the engine into failure mode or open loop fuel control. This will also cause the vehicle to fail emissions testing.

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.

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 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 are the symptoms of a p2241 trouble code?

Symptoms of a P2241 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? Causes for this code may include: Defective oxygen sensor/s

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)

What does p2241 mean on an O2 sensor?

A stored code P2241 means that the powertrain control module (PCM) has detected a positive current discrepancy in the upstream oxygen (O2) sensor for engine bank number two. Bank two is the engine bank that doesn’t contain the number one cylinder.

How many O2 sensors does a 2005 Toyota Avalon have?

Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.

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.

Where can I get an oxygen sensor for my Toyota Avalon?

All genuine Toyota Oxygen Sensor from us are shipped directly from authorized Toyota Dealer. If you want search for Avalon Oxygen Sensor fast and easily, we assure you that you get to opt for one in less the time. Item has been added to your cart! This part contains hazardous material.

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.
