If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the p105d fault code.

  • The symptoms of the automobile fault code p105d include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p105d can be caused by a faulty O2 sensor heater, an open or shorted harness, a poor electrical connection in the circuit, or a faulty Engine Control Module (ECM).

  • The fault code p105d can be caused by: a faulty O2 Sensor Heater Bank 2 Sensor 2, an open or shorted O2 Sensor Heater Bank 2 Sensor 2 harness, a poor electrical connection in the O2 Sensor Heater Bank 2 Sensor 2 circuit, or a faulty Engine Control Module (ECM).

To fix the automobile fault code p105d, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p105d, first, check 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 connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The automobile fault code p105d diagnosis and fixing cost is influenced by the estimated repair time of 1.0 hour. Most auto repair shops charge between $75 and $150 per hour for their services.

The P105D fault code refers to the O2 sensor heater circuit performance for bank 2 sensor 2. This sensor is located behind the Three-Way Catalytic Converter (TWC) and is responsible for detecting the oxygen concentration in the exhaust gas.

The heated oxygen sensor helps the Engine Control Module (ECM) deliver accurate air fuel ratio control by providing information about the post-TWC air fuel ratio.

When the air fuel ratio is lean, the oxygen concentration in the exhaust gas is high, and the sensor informs the ECM that the ratio is lean.

Conversely, when the air fuel ratio is rich, the oxygen concentration is low, and the sensor informs the ECM that the ratio is rich. If the heated oxygen sensor is not functioning properly due to internal malfunctions, the ECM is unable to compensate for deviations in the primary air fuel ratio control.

This can lead to issues with the purification rate of carbon monoxide, hydrocarbon, and nitrogen oxide components in the exhaust gas. It is important to address this fault code to ensure optimal performance and emissions control.

What are the possible causes of the automobile fault code p105d?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P105D could be the culprit. This code is often caused by a faulty O2 sensor heater in bank 2 sensor 2, an open or shorted harness, a poor electrical connection in the circuit, or a faulty engine control module (ECM). To fix the 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.

How can I visually inspect the wiring harness and connectors to fix the fault code p105d?

If you’re dealing with the fault code p105d and your engine light is on, it’s time to take action. The most likely cause is a faulty O2 Sensor Heater Bank 2 Sensor 2 or a problem with the wiring harness and connectors. To fix this, 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 quickly. 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 fault code p105d?

If you’re dealing with the fault code p105d and your engine light is on, it’s important to check for damaged components and connector’s pins. This code is often caused by a faulty O2 Sensor Heater Bank 2 Sensor 2 or issues with the wiring harness and connectors. To resolve the issue, visually inspect the wiring harness and connectors, paying close attention to any broken, bent, pushed out, or corroded pins. This simple step can help you identify and fix the problem efficiently.
