[SOLVED] P1150 Code: Fixing Air/Fuel Ratio Sensor Circuit Range/Performance Issue

If you’ve noticed the engine light or service engine soon warning light illuminated on your dashboard, it could be due to the automobile fault code P1150.

This code indicates a problem with the Air Fuel Ratio (AF) Bank 2 Sensor 1. The possible causes include a faulty sensor, an open or shorted harness, poor electrical connection, fuel pressure issues, fuel injector problems, or intake air leaks.

To fix this issue, start by visually inspecting the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins on the connectors. This repair is of moderate difficulty and should take around 1.0 hour to complete.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1150 fault code.

  • The symptoms of the automobile fault code P1150 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1150 can be caused by a faulty AF sensor, open or shorted harness, poor electrical connection, fuel pressure issues, fuel injector problems, or intake air leaks.

  • The fault code P1150 can be caused by a faulty Air fuel Ratio (A/F) Bank 2 Sensor 1, an open or shorted harness for the Air fuel Ratio (A/F) Bank 2 Sensor 1, a poor electrical connection in the Air fuel Ratio (A/F) Bank 2 Sensor 1 circuit, issues with fuel pressure, problems with the fuel injector, and intake air leaks.

To fix the p1150 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1150, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1150 are the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P1150 fault code indicates a problem with the Air-Fuel Ratio (AF) sensor circuit in Bank 2 of the engine. This sensor is responsible for measuring the air-fuel ratio and providing feedback to the Engine Control Module (ECM). The ECM uses the output voltage from the AF sensor to determine if the air-fuel ratio is too rich or too lean.

It then adjusts the stoichiometric air-fuel ratio accordingly.

In addition, the ECM checks the fuel injection volume compensation value to assess the condition of the AF sensor.

If there is a deterioration in the AF sensor’s response, it can be detected by comparing the variation in the sensor’s output voltage with the fuel trim variation.

The P1150 fault code alerts the driver and technician that there is a range or performance issue with the AF sensor circuit in Bank 2.

It is important to address this issue promptly to ensure optimal engine performance and fuel efficiency.

What are the possible causes of the p1150 fault code and how can I visually inspect them?

If you’re experiencing the dreaded p1150 fault code, there are a few possible causes to consider. It could be a faulty Air fuel Ratio (A/F) Bank 2 Sensor 1, an open or shorted harness, a poor electrical connection in the circuit, fuel pressure issues, fuel injector problems, or even intake air leaks. To visually inspect these potential culprits, take a close look at the wiring harness and connectors. Check for any signs of damage, and pay special attention to broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to check the “Possible Causes” listed above for a more comprehensive troubleshooting guide.

How can I determine if the wiring harness and connectors related to the Air fuel Ratio (A/F) Bank 2 Sensor 1 are damaged?

If your engine light is on and you suspect a problem with the Air fuel Ratio (A/F) Bank 2 Sensor 1, there are a few things you can do to determine if the wiring harness and connectors are damaged. First, visually inspect the wiring harness and connectors for any signs of damage. Look for broken, bent, pushed out, or corroded connector pins. If you find any damaged components, they may need to be repaired or replaced. Checking for poor electrical connections and fuel pressure, as well as inspecting the fuel injector and looking for intake air leaks, can also help identify the issue.

What steps should I take to check for broken, bent, pushed out, or corroded connector’s pins in order to fix the p1150 fault code?

If you’re dealing with the p1150 fault code and your engine light is on, here’s what you can do. First, check for a faulty Air fuel Ratio (A/F) Bank 2 Sensor 1 or an open or shorted harness. Next, inspect the wiring harness and connectors for any damage. Pay close attention to the connector’s pins – make sure they’re not broken, bent, pushed out, or corroded. This thorough visual inspection can help you identify and fix the issue.
