What does the code P0138 mean?
When trouble code P0138 is set, this indicates that there is a high voltage (steadily above . 9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on the bank 1 of the engine.
What is the cause of the code p0138?
What Is the Cause of Code P0138? 1 Faulty O2 Sensor 2 Short to battery voltage in O2 sensor signal circuit 3 Corroded wiring 4 Fuel pressure too high 5 Engine coolant temperature sensor
What does the p0138 Jeep O2 sensor 2 mean?
P0138 JEEP Meaning The Heated Oxygen Sensor 2 (HO2S) (Rear O2 Sensor), 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 is the OBD code for bank 1 sensor 2?
P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.
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 is code p0138 and p0607?
P0138 is for the O2 sensor. Either shorted or open. P0607 is for ECM problem. Most likely the O2 is the main cause of the problem and the code for a bad ECM is thown in just in case raplacing the O2 sensor or checking the wire harness do not fix the problem.
What does trouble code p1138 mean?
The P1138 code is detected when the target opening angle of swirl control valve controlled by Engine Control Module (ECM) and the input signal from swirl control valve position sensor is not in the normal rang.
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.
