How do I fix error P0138?

What repairs can fix the P0138 code?

1. Replacing the O2 sensor for bank 1 sensor 2.
2. Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
3. Replacing the catalyst in front of the sensor.
4. Repairing a leaking injector.

What can cause a P0138 code?

What Is the Cause of Code P0138?

• Faulty O2 Sensor.
• Short to battery voltage in O2 sensor signal circuit.
• Corroded wiring.
• Fuel pressure too high.
• Engine coolant temperature sensor.

How many O2 sensors does a 2000 Dodge Durango have?

the 2000 parts catalog only shows one o2 sensor config for the 4.7L (EV0), using 4 o2 sensors..

How do you fix a high voltage O2 sensor?

The number one most common repair for this problem is replacing the O2 Sensor itself. Another repair would be to replace the wiring or connection for Bank 1, Sensor 2. If the catalyst is the problem, replace the catalytic converter. Replace the fuel injector if it is leaking.

What is diagnostic code P0141?

Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.

Can a bad battery trigger check engine light?

A bad battery can cause problems in electrical and electronic parts, including the computer. It can even cause a “Check Engine” light.

Can a bad O2 sensor cause a random misfire code?

If an oxygen sensor or mass airflow sensor is failing, it could give incorrect data to your engine’s computer, causing the misfire. When a vacuum line is broken, it can cause a fuel-injected motor to misfire.

How many O2 sensors does a 2001 Dodge Durango have?

Amazon.com: Set of 4 Upstream and Downstream Oxygen Sensor for Dodge Durango 2001-2002 Dakota 2001 V8 4.7L : Automotive.

What is code P0141?

What is code P0132?

Diagnostic trouble code (DTC) P0132 stands for “Oxygen Sensor Circuit High Voltage (Bank 1, Sensor 1).” It involves the vehicle’s oxygen sensor, specifically the #1 sensor on Bank 1. This code is triggered when the PCM or powertrain control module detects that your heated oxygen sensor reading is too high.

What causes the p0138 OBDII code on a Dodge Ram?

P0138 is a common OBDII code that occurs in many vehicles, including the Dodge Ram. 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.

What does the p0138 code on the O2 sensor 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. 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 Dodge Ram?

P0138 is a common OBDII code that occurs in many vehicles, including the Dodge Ram. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more
