If you see the engine light or service engine soon warning light illuminated on your dashboard, it could be due to the automobile fault code: p1199.

This code is typically 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 related to the O2 sensor.

Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This repair should take approximately 1.0 hour. Remember to check the “Possible Causes” listed above for a more accurate diagnosis.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1199 fault code.

  • The symptoms of the automobile fault code P1199 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1199 can be caused by a faulty O2 sensor, an open or shorted O2 sensor harness, or a poor electrical connection in the O2 sensor circuit.

  • The fault code P1199 can be caused by the following: a faulty O2 sensor, an open or shorted O2 sensor harness, and a poor electrical connection in the O2 sensor circuit.

To fix the automobile fault code p1199, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1199, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded pins on the connectors.
  • This fix typically takes around 1.0 hour to complete.

The factors influencing the diagnosis and fixing cost of the automobile fault code p1199 are the estimated repair time of 1.0 hour and the average hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P1199 fault code refers to an issue with the O2S (Oxygen Sensor) Heater Circuit for Bank 2 Sensor 2.

This circuit is responsible for heating the oxygen sensor to a minimum operating temperature of 750 degrees F. The faster the sensor reaches this temperature, the faster it can send an accurate signal to the Engine Control Module (ECM). To achieve the required temperature, a heater element is included inside the oxygen sensor. The ECM controls this heater element based on signals from the engine coolant temperature and engine load.

It allows current flow to ground to control the heater element circuit. The ECM monitors the voltage signal received through the heater element circuit and compares it with factory specifications to determine the state of the circuit. If there is an electrical malfunction in the O2S Heater Circuit for Bank 2 Sensor 2, the P1199 fault code will be triggered. This code indicates that there is an issue with the electrical system of the oxygen sensor heater circuit.

What are the possible causes of fault code P1199 in an automobile?

If you see the engine light or service engine soon warning light on in your automobile, it could be due to fault code P1199. 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, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix fault code P1199?

To fix fault code P1199, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify if the issue lies with a faulty O2 sensor, an open or shorted O2 sensor harness, or a poor electrical connection in the O2 sensor circuit. Take note of the possible causes mentioned and address them accordingly.

What should I look for when checking for damaged components and corroded connector’s pins to resolve fault code P1199?

When resolving fault code P1199, start by checking for damaged components and corroded connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By addressing these issues, you can effectively fix the problem and turn off the Engine Light or Service Engine Soon Warning Light.
