Where is P0137 located?

The sensor located before the catalytic converter is the upstream sensor, also known as Sensor 1. The one after the catalytic converter, which is the downstream sensor, is Sensor 2. To understand code P0137 better, you have to first understand how O2 sensors work together.

Can I drive my car with code P0157?

Driving with trouble code P0157 is acceptable but only for a short period of time. Driving with this code for an elongated period of time could result in greater engine damage if it is being caused by a lean air-fuel ratio.

What does low circuit mean?

Sensor Reference Voltage
<Sensor Reference Voltage “A” Circuit Low”. This code means that the powertrain control module (PCM) has detected a low reference voltage signal for a particular sensor that has been given the designation “A”.

What is a po430?

Code P0430 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.

What causes P0131?

Code P0131 is a result of the oxygen A/F sensor incorrectly detecting the air to fuel ratio of the exhaust. This DTC code is the result of this ECM detecting either a voltage outside of the specified range, or an improper air to fuel ratio.

What causes low O2 sensors?

Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.

What does trouble code p0137 mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1.

What causes engine code p0138?

The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time. Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light)

What does code p0136 mean?

A P0136 code may indicates that the the powertrain computer or PCM detects that the oxygen sensor voltage has remained below the expected range (in a lean condition, or below 400 millivolts) for too long. This criteria can vary from model to model.

What does code p0137 mean on a Sebring?

The P0137 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively low for an extended period of time. The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank.
