How do I fix code po137?

What repairs can fix the P0137 code?

1. Replacing the O2 sensor for bank 1 sensor 2.
2. Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
3. Repairing exhaust leaks before the sensor.

What causes po137?

Here are the most common causes of an O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) problem or code P0137: Malfunctioning O2 sensor (including a bad heater) Lean running condition (this will also be reflected by positive fuel trim readings)

What is a bank 1 sensor 2?

“Bank 1, Sensor 2” is the rear oxygen sensor. Typically, the engine bank that. contains cylinder 1 is called Bank 1. A V6 or V8 engine has two banks (or two parts of that “V”). Usually, the bank that contains the cylinder number 1 is called “Bank 1.”

What does p0137 mean on a check engine light?

P0137 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.

When does p0137 trigger in a catalytic converter?

In contrast, downstream sensors (sensor 2) generate a fairly steady voltage when the catalytic converter is working properly. Code P0137 triggers when the PCM detects that the signal from sensor 2 on Bank 1 was below a specific value for a certain amount of time.

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 a code p0137 on the ECM mean?

This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set. There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination. A code P0137 may mean that one or more of the following has happened:
