Hey there!

If you’ve got an engine light on or a service engine soon warning light, it’s time to pay attention. The fault code P1154 is indicating a problem with the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1. This could be due to a faulty sensor, an open or shorted harness, or a poor electrical connection in the circuit.

To fix this, start by visually inspecting the wiring harness and connectors.

Look out for any damaged components or broken, bent, pushed out, or corroded connector pins. It’s important to address this issue as soon as possible to prevent any further damage.

The repair time for this is estimated to be around 1.0. Hope this helps!

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1154 fault code.

  • The symptoms of the automobile fault code P1154 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1154 can be caused by a faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, an open or shorted harness, or a poor electrical connection in the circuit.

  • The fault code P1154 can be caused by the following: 1.
  • Faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1.
  • 2.
  • Open or shorted harness of Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1.
  • 3.
  • Poor electrical connection in the circuit of Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1.

To fix fault code p1154, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1154, 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 connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The automobile fault code P1154 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of the repair may vary depending on the auto repair shop, with most shops charging between $75 and $150 per hour.

The P1154 fault code refers to the Heated Oxygen Sensor (HO2S) Transition Time Ratio Bank 2 S. The Powertrain Control Module (PCM) constantly monitors the activity of the HO2S for 100 seconds.

It counts the number of times the sensor switches from rich to lean and from lean to rich, and calculates the time it takes for these transitions.

By determining the average time for all transitions, the PCM can then divide the rich to lean average by the lean to rich average to obtain a ratio.

This ratio helps the PCM assess the performance of the HO2S in Bank 2.

What are the possible causes of the P1154 fault code in an automobile?

If you’re seeing the P1154 fault code in your automobile, it means that your engine light is on or you have a service engine soon warning light. The possible causes for this code include a faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, an open or shorted HO2S Bank 2 Sensor 1 harness, or a poor electrical connection in the HO2S Bank 2 Sensor 1 circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.
