What causes a P0137 code?

What causes a P0137 code?

What Does P0137 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. When trouble code P0137 is set, this indicates that there is low voltage (roughly 450 millivolts or less) for more than 20 seconds coming from the bank 1 sensor 2 oxygen sensor.

When is the p0137 code detected in an engine?

When is the P0137 code detected? 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.

How much does it cost to repair a p0137 Chevy?

Replacing the Rear Heated Oxygen Sensor Bank 1 usually takes care of the problem. What does this mean? The cost of diagnosing the P0137 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

What is the code for check engine light?

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 for $0.0 .

When is the P0137 code detected? 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.

What causes the p0137 code on a Toyota RAV4?

Here are the most common issues that cause the P0137 code in the Toyota Rav4. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0137 is triggering your service engine soon light.

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.
