What does the p0138 code mean on a Chrysler?
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. 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.
What is the OBDII code on a Jeep Liberty?
P0138 is a common OBDII code that occurs in many vehicles, including the Jeep Liberty. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more There are also some less likely problems that can cause P0138. We’ll go over those below. Here’s a pretty helpful video from AutoEclinic on diagnosing the code:
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.
How to diagnose an oxygen sensor on a Jeep Liberty?
It is possible to diagnose the P0138 with a multimeter. If you use the multimeter, you’ll know whether or not the voltage coming to and from the oxygen sensor is within spec, this can help you determine if it’s your Liberty’s O2 sensor, or wiring harness that’s the issue.

What is the oxygen sensor code on a Jeep Liberty?
Jeep Liberty P0138: Oxygen Sensor High Voltage (Bank 1 -Sensor 2) P0138 is a common OBDII code that occurs in many vehicles, including theJeep Liberty. The code is triggered when: There are also some less likely problems that can cause P0138.

What does p0138 mean in a catalytic converter?
O2 Sensor Circuit High Voltage (Bank 1, Sensor 2) What Does P0138 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. It measures the amount of air and fuel coming out of the catalytic converter to ensure the catalytic converter is functioning properly.
What does a code p0139 mean on a car?
A code P0139 may mean that one or more of the following has happened: The oxygen sensor is faulty. The wiring to the sensor is broken / frayed. There is an exhaust leak.
What does the p0138 code on the ECM mean?
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.
How much does it cost to repair Nissan p0138 code?
The cost of diagnosing the P0138 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. When is the code detected?
A code P0139 may mean that one or more of the following has happened: The oxygen sensor is faulty. The wiring to the sensor is broken / frayed. There is an exhaust leak.
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:
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 trouble code for the O2 sensor?
Faulty o2 sensor Exhaust leak near the rear sensor Short to voltage on O2 signal circuit High resistance or open on O2 signal circuit Engine running very rich or lean Fuel pressure very high or low – fuel pump or pressure regulator Repair exhaust leak near the rear sensor Check for restriction in catalyst and replace as necessary
