6.0 Powerstroke engine cars face several issues due to extreme fuel running. Some error codes indicate issues related to oil temperature, and P0198 is one of them. P0198 is a common diagnostic error code for high engine oil temperature sensors. This error code appears when the engine oil temperature is higher than necessary. This issue can be serious if one does not fix the error code on time. In this article, we shall discuss what code P0198 is on the 6.0 Powerstroke and how to fix it.
What is the P0189 code On 6.0 Powerstroke and what causes it?
As we have mentioned earlier, the P0198 error code indicates a high engine oil temperature. The sensor detects the high temperature automatically and gives you a signal. There may be several causes behind the P0198 error code on 6.0 Powerstroke. However, some common causes may lead to this error code.
Short circuit in EOT
A short circuit in the EOT location can cause the P0198 error code. This error usually occurs due to wrong or damaged wiring. However, blown-out circuits can cause issues in the EOT as well.
Faulty PCM
The Powertrain Control Module (PCM) can sometimes be faulty and show false readings. The PCM is like the memory of a car that collects all the information from different sensors. The PCM will send you a false P0198 code when the sensor detects wrong information.
ECU issue
The Engine Control Unit (ECU) of a car is in charge of all the operations related to the engine. Due to any unexpected reason or damaged ECU, the check engine light may show up. Even if there is no real issue with the oil temperature, the check engine light will give you the P0198 error code. Sometimes the light does not go off until you fix the issue.
High Engine Oil Temperature
Excess oil temperature is the main cause of the P0198 error code. This happens mostly because the engine gets heated up sometimes, and the oil temperature rises. When the oil temperature increases, the sensor detects it immediately and gives you a signal with the error code. On the other hand low engine oil temperature causes the Code P0197 on 6.0 Powerstroke.
Which engines are prone to the P0198 error code?
High-powered engine cars like Ford, Toyota, Nissan, Jeep, and BMW face the P0198 error code very frequently. This is because cars with powerful engines run on excessive fuel and generate heat which can sometimes be an issue. Therefore, the P0198 error code can appear very often if you regularly use 6.0 Powerstroke engine cars.
Where is the engine oil temperature sensor located?
The engine oil temperature sensor is the main component that detects any issues with the engine. The sensor is inside the engine compartment, where there are all kinds of engine wiring. The exact location inside the engine compartment can vary depending on the car brand. But, most of the time, you can locate the sensor near the thermostat or inside it.
What are the symptoms of the P0198 code On 6.0 Powerstroke?
You can detect the P0198 error code when the check engine light shows up. The check engine light is located on the dashboard, and you can easily notice when the light comes up. The light is the only symptom of the P0198 code.
How to avoid the P0198 error code On 6.0 Powerstroke?
There is no way you can avoid the P0198 error code on the 6.0 Powerstroke. You must not ignore the error code because it will bring you trouble. To get rid of the error code, you must detect and fix the issue as soon as possible.
How to diagnose the P0198 code On 6.0 Powerstroke?
Since it is a bit tricky to diagnose the P0189 error code, you would need help from an expert. You have to assign the task to a good mechanic. The mechanic will find out the root of the issue by checking the EOT electrical system. The next step is to examine the sensor information and use a scan tool to test the error code. The EOT circuit is tested by a multimeter. After testing the circuit, it’s time to check each wire and detach them. The mechanic will find out which wiring has a problem and isolate it for further testing. The test results of a multimeter are not always correct on the first try. Therefore, it is necessary to test multiple times. When the exact voltage shows up, it’s time to rearrange the wire or change it if it is damaged. Once the mechanic attaches new wiring, the error code will go off.
What are common mistakes while diagnosing the P0198 error code?
While diagnosing the P0198 error code, mechanics make some common mistakes. As a result, they miss out on checking for some issues that may help diagnose the error code faster.
Sometimes the mechanic assumes that the issue is with the sensor and skips checking for damaged wiring. Instead, the mechanic replaces the sensor, which eventually does not work because the actual problem remains in the wires.
Low or high oil temperature can be caused by several reasons. The mechanic might assume and start working on that specific issue instead of checking for other problems.
If there is a problem with the issue, it is necessary to check if the PCM is faulty. Unfortunately, mechanics tend to change the sensor directly instead of checking the PCM, even though the sensor is perfectly fine.
How serious is the P0198 error code, and how to repair it?
The P0189 error can be very serious if there is an actual issue in the EOT. This issue may lead to serious accidents when your car is heated up. Therefore, it is necessary to fix the error code immediately, and there are some ways to repair it.
Repairing damaged wires
The first thing you need to check is the wiring. You must detach and isolate each wire to find the bad one if there are damaged wires. Once you figure out the damaged wire, you might have to change it or tape it back. Then, after arranging the wiring back into the same position, you can check if the error code is finally fixed.
Repairing PCM
If there is an issue with the PCM, most of the time, it’s not fixable. Especially if there is a short circuit problem. In that case, you have to replace the PCM or get a new one. You can ask a mechanic to try and check the issues in the PCM, but they would suggest you replace it eventually.
Replacing EOT sensor
A faulty sensor may give you the wrong information when you detect the issue behind high/low oil engine temperature. Depending on the brand of your car, the mechanic will use a specific procedure to repair the sensor. But in most cases, you have to replace the faulty sensor. In addition, you might face the issue again if something goes wrong with a sensor. So, it’s wise to change it to avoid false readings.
How much does repairing the P0198 error code on 6.0 Powerstroke cost?
Mechanics will typically charge you $80 to $150 per hour, depending on the depth of the issue. The charges may differ depending on car brands as well.
Error codes are common when you use cars with high-power engines. Since you cannot avoid these error codes, it is essential to have some knowledge of them. Remember, if you detect the P0198 error code, you must fix it soon because this can be hazardous. Hopefully, the article has helped you understand what code P0198 is on 6.0 Powerstroke and how to fix it!
