What is engine code P0136?
What is engine code P0136?
Your Engine Control Module (ECM) uses the voltage levels provided by your O2 sensors to regulate your engine’s fuel injector pulse. If you are seeing code P0136, it means that the O2 sensor behind your catalytic converter on bank 1 is malfunctioning.
How many O2 sensors does a 2004 Ford Escape have?
The Ford Escape has two oxygen sensors on it for its four cylinder engine. There is one that is on the exhaust before the catalytic converter and one that is after. You can find them since they are screwed into bungs that are welded onto Your headers and exhaust.
Where are the O2 sensors located on a 2004 Ford Escape?
The O2 sensor is mounted at the top of the B1 cat. The cat is an upright unit, between and easily distinguishable from the manifold and exhaust pipe. The O2 is mounted near horizontal and pointing out toward the left front.
What causes the p0136 code on a Ford Escape?
Here are the most common issues that cause the P0136 code in the Escape. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The oxygen sensor itself is one of the most likely reasons that P0136 is triggering your service engine soon light.
What is the O2 sensor code on a Ford Escape?
P0136is a common OBDII code that occurs in the Ford Escape. It is typically caused when the O2 Sensor voltage is not within normal operating range. Bank one will be the side of the engine with cylinder 1 in the firing order. Ford Escape P0136 Symptoms
What does the DTC code p0136 stand for?
Diagnostic trouble code (DTC) P0136 stands for “O2 Sensor Circuit (Bank 1, Sensor 2).” It refers to the same malfunction as the engine code P0137, except it applies to the second O2 sensor on Bank 1. The P0136 code triggers when the ECM believes that the Bank 1 O2 sensor is not operating correctly.
When does the p0136 code trigger the ECM?
The P0136 code triggers when the ECM believes that the Bank 1 O2 sensor is not operating correctly. Because this is a generic code, it’s supported by various makes and models.

What is the p0136 Ford heated oxygen sensor 2?
P0136 Ford Description The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. For optimum catalyst operation, the air fuel mixture (air-fuel ratio) must be maintained near the ideal stoichiometric ratio.
What does a p0136 code on a B2S2 mean?
Most of the time, a P0136 code means that the O2 sensor has become faulty or that there is a leak in the air intake system. On most models, the B2S2 O2 sensor is relatively easy to access and inexpensive to replace, so replacement is likely the first option.
