If you see the engine light or service engine soon warning light illuminated in your car, it could be due to the fault code P1137. This code is typically caused by exhaust gas leaks, a faulty heated oxygen sensor 2 (HO2S2) downstream bank 1, an open or shorted harness for the heated oxygen sensor, poor electrical connection in the circuit, inappropriate fuel pressure, or faulty fuel injectors. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or broken pins.

The repair time for this problem is estimated to be around 1.0 hour. Make sure to address this issue promptly to avoid any further complications.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1137 fault code.

  • The symptoms of the automobile fault code P1137 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code P1137 can be caused by exhaust gas leaks, a faulty Heated Oxygen Sensor 2 (HO2S2) (Downstream) Bank 1, open or shorted harness, poor electrical connection, inappropriate fuel pressure, or faulty fuel injectors.

  • The fault code P1137 can be caused by various factors, including exhaust gas leaks, a faulty Heated Oxygen Sensor 2 (HO2S2) (Downstream) Bank 1, an open or shorted harness for Heated Oxygen Sensor 2 Bank 1, a poor electrical connection in the Heated Oxygen Sensor 2 Bank 1 circuit, inappropriate fuel pressure, and faulty fuel injectors.

To fix the p1137 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P1137, 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 if there are any broken, bent, pushed out, or corroded pins in the connectors.
  • This fix typically takes around 1.0 hour to complete.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1137 include the estimated repair time of 1.0 hour.

Most auto repair shops typically charge between $75 and $150 per hour for their services.

These factors contribute to the overall cost of resolving the fault code.

The P1137 fault code refers to a lack of heated oxygen sensor switches on bank 1 sensor 2, indicating a lean air-fuel mixture.

The heated oxygen sensor 2 (HO2S2) monitors the oxygen level in the exhaust gas after the three-way catalyst. It is crucial for the catalyst’s optimal operation that the air-fuel mixture maintains a near stoichiometric ratio.

The PCM adjusts the fuel injection time based on the HO2S2 output voltage, aiming for a nearly stoichiometric air-fuel ratio.

When the HO2S2 voltage drops below 0.45 V, the PCM interprets it as a lean air-fuel ratio. Conversely, when the voltage exceeds 0.45 V, the PCM interprets it as a rich air-fuel ratio. The P1137 code is triggered when the PCM detects that the HO2S2 signal remains below the voltage range for an extended period.

This indicates a lack of heated oxygen sensor switches on bank 1 sensor 2, suggesting a lean air-fuel mixture.

What are the possible causes of the automobile fault code P1137?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1137 could be the culprit. This code can be caused by a few different things, including exhaust gas leaks, a faulty heated oxygen sensor 2 (HO2S2) downstream bank 1, an open or shorted harness for the heated oxygen sensor, poor electrical connection in the circuit, inappropriate fuel pressure, or faulty fuel injectors. To fix the issue, start by visually inspecting the wiring harness and connectors, checking for any damage or broken pins.
