If the check engine light on your Jeep Cherokee comes on, it’s advisable to bring it in for diagnostic testing. While the look of the lights varies from vehicle to vehicle, they always serve the same purpose. This indicates that there is an issue with the vehicle’s emissions system. The engine control unit and diagnostics system are responsible for tracking the P0132 Jeep Cherokee Error Code.
We will cover every aspect and also discuss several methods for resolving the P0132 problem in simple stages.
How is the P0132 Error Defined?
The P0132 trouble code is one of a large number of diagnostic trouble codes (DTC) kept in the computer of a vehicle. Each vehicle has a computer module, referred to as the PCM (powertrain control module), which includes the ECU (engine control unit) and TCU (transmission control unit).
The car’s brain computers are in charge of monitoring and improving engine and gearbox performance. They do this by utilizing a variety of sensors and transmitting inputs that can trigger issue codes. A trouble code is a diagnostic instrument that can inform a mechanic of the source of a problem.
The PCM holds a variety of trouble or error codes that are set in the event of an engine malfunction. Faulty PCMs may also generate random codes, which is why it is recommended to contact a qualified technician to diagnose and resolve the issue anytime a trouble code is established.
Symptoms of Jeep Cherokee P0132
Typically, the sole symptom of P0132 error is the blinking service engine light. Additional symptoms may occur in some circumstances. These signs are the following:
• A rough running engine.
• Foul-smelling exhaust.
• The service light is illuminated.
• Inadequate MPG.
Generally, it is not a risk of a breakdown. However, it is essential to repair the illuminated engine light as soon as possible.
Causes of Jeep Cherokee Code P0132
The reasons for a Code P0123 are all connected to the O2 sensors’ functionality. The signal indicates that the O2 sensors are malfunctioning. While the most common reason is that the O2 sensors have failed, there are various other possibilities.
The O2 sensor has malfunctioned – This is the most often occurring reason for a P0123 code. O2 sensors should be changed every 60,000 to 90,000 miles, however, they may fail sooner. While changing the sensors immediately is not a smart idea. Consider other reasons to avoid discarding perfectly excellent O2 sensors.
Incorrect O2 sensors inserted – This is a possibility only if the O2 sensors were recently replaced and the incorrect one was put.
Damage to the wiring harness connecting to and from the O2 sensor — Wires are prone to damage, and the wire harness around the O2 sensors is no exception. This is worth checking before replacing your O2 sensors.
Damage to the O2 sensor terminal — It is possible that the terminal on which the sensors are placed has been damaged.
Methods to Resolve the P0132 Jeep Cherokee Error Code
If you are certain that the P0132 error code is present, the following procedures will provide a remedy to the issue. We recommend that you clean and maintain the oxygen sensor prior to replacing it, as well as inspecting the intake manifold.
Replacing Defective Hardware
If the wires are broken, they must be replaced. Replacement components are available for less than $50 at your local auto store or on Amazon.
What is the Process of Replacing the O2 Oxygen Sensor?
While replacing the O2 sensor might be challenging, if you enjoy delving into the components of your car, you can simply change the O2 sensor on your own.
Step 1: is to Start the Engine
It is prudent to start the engine and let it run for a few minutes.
Step 2: is to Unlink the Negative End of the Battery
In this step, the engine must be turned off. Then detach the negative end of the battery connector to protect yourself from electric shock.
Step 3: Locate the O2 Sensor
After completing step 2, locate the O2 sensor which is at the catalytic converter’s front side. It resembles a spark plug. If you’re having trouble locating it, review your vehicle’s owner’s handbook.
Step 4: Disconnecting the electrical supply
Disconnect the oxygen sensor’s electrical connection. To insert the tab, you will need a screwdriver. Then, carefully remove the connection.
Step 5: Remove the Oxygen sensor
Gently loosen the sensor using a socket wrench and then install the new sensor.
Step 6: Connect the New Sensor
Connect the electrical connection to the new O2 sensor. Then reconnect the battery’s negative pole and start the engine. Reset the problem code with the OBD2 scanner and cross your fingers that it does not reappear.
Should I Immediately Repair the P0132 Error Code?
Although error code P0132 does not create a significant drivability problem, it should not be ignored for an extended period of time since it affects the vehicle’s fuel consumption and causes it to spew dangerous pollutants.
What is the Cost to Replace an Oxygen Sensor?
The typical cost of replacing the O2 sensor is around $250; the sensor itself is approximately $117 and labor is approximately $150. Prices may vary according to the vehicle’s type and manufacturer.
A P0123 error number indicates that your Jeep Cherokee’s O2 sensors are malfunctioning. It is critical to inspect the sensors, cables, and terminal for damage prior to changing any parts to prevent adding to your workload.
After going through the article, you can understand that replacement components are reasonably priced, and repairs are simple enough for a novice to perform. If you are ready to handle the job yourself, a P0123 error code is unlikely to compel you to send your car to a shop for repairs.
