What causes the p0138 code on an engine?

What causes the P0138 code? 1 The engine control module (ECM) sees the voltage of the O2 sensor for bank 1 sensor 2 above 1.2 volts… 2 The ECM detects the voltage high problem and turns on the Check Engine Light. 3 The ECM uses other O2 sensors to try and control the fuel injection with their values.

What does p0137 mean on an engine control module?

Coming back to P0137, this code is generated when the engine control module (ECM) detects that the O2 oxygen sensor for bank 1 voltage has stayed below 400 millivolts (0.21 volts) for more than twenty seconds. Another reason for this code to trigger is that the air/fuel ratio sensor remains lean mode for over 2 minutes.

What does the p2270 code on the O2 sensor mean?

What the P2270 code means. P2270 is an OBD-II generic code for the O2 sensor signal stuck lean on bank 1 sensor 2 to the engine control module (ECM). This means that the O2 sensor in bank 1 sensor 2 indicates either too much oxygen in the exhaust stream, an open circuit, or a defective sensor which causes a lean signal to the ECM.

What is the p0137 code for oxugen sensor 2?

Code P0137 triggers when the PCM detects that the signal from oxugen sensor 2 on Bank 1 is below a specific value for a certain amount of time. The Bank 1 portion of the code refers to the side where the #1 cylinder is located. There are two O2 sensors in your vehicle.

What does p0137 mean on an oxygen sensor?

For example, a P0137 on a Toyota translates to “Oxygen Sensor Circuit Low Voltage Bank 1, Sensor 2”; a P0137 on a Chevy, meanwhile, is “Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1, Sensor 2”. Since translations vary, the possible causes may also differ depending on the make and model of your vehicle.

Step 2: Determine the meaning of the letter. There are four possible letters that can be displayed in the first section. The letter “P” indicates powertrain-related codes such as those involving the engine or the transmission and their sensors. Typically, “P” codes are the only ones that will illuminate the Check Engine Light.

How to read and understand check engine light ( OBD )?

You will need an OBD scan tool. The scanner allows you to communicate with the computer and retrieve the trouble codes. Certain scanners may give information on what the revealed code means, but most will just give a five digit number and letter combination. Follow these 4 steps to insert and read the OBD scanner:

How to test Acura check engine light codes?
