The estimated repair time for this fault code is 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p1198 fault code.

The P1198 fault code refers to an issue with the O2S (Oxygen Sensor) heater circuit in Bank 1 Sensor 2. This circuit is responsible for reaching a minimum operating temperature of 750 degrees F to produce an accurate voltage signal.

The faster the sensor reaches this temperature, the quicker it can send an accurate signal to the Engine Control Module (ECM).

To achieve this temperature, a heater element is included inside the sensor, which is controlled by the ECM based on signals from the engine coolant temperature and engine load. The ECM monitors the voltage signal received through the heater element circuit and compares it to factory specifications to determine the state of the circuit. If there is an electrical malfunction in this circuit, the P1198 code will be triggered.

What are the possible causes of the automobile fault code P1198?

If you see the engine light or service engine soon warning light on, the fault code P1198 could be the culprit. This code is often caused by a faulty O2 sensor, an open or shorted O2 sensor harness, or a poor electrical connection in the O2 sensor circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes mentioned above for a comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the P1198 fault code?

If you’re dealing with the P1198 fault code and your engine light is on, it’s time to take action. The most common cause of this code is a faulty O2 sensor or issues with the O2 sensor harness. To fix it, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step can help you identify and resolve the issue. Don’t delay, get to the bottom of the problem and get your engine running smoothly again.

What should I look for when checking for damaged components and connector’s pins to resolve the P1198 fault code?

When resolving the P1198 fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. These issues can cause a poor electrical connection and lead to the engine light being on. By addressing these potential causes, you can effectively fix the problem and resolve the fault code.
