What is 02 circuit low voltage?

What is 02 circuit low voltage?

Diagnostic trouble code (DTC) P0131 stands for “O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1).” It indicates that the voltage of the affected oxygen sensor stayed below a certain threshold or the air-fuel ratio sensor stayed in a lean-biased mode for too long.

What does code p0137 mean on O2 sensor?

There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination. A code P0137 may mean that one or more of the following has happened: Faulty o2 sensor Exhaust leak near the rear sensor Short to voltage on O2 signal circuit High resistance or open on O2 signal circuit

Why is Bank 1 sensor 2 low voltage?

The O2 sensor circuit for bank 1 sensor 2 is used to give a voltage feedback to the ECM showing how much oxygen is in the exhaust stream to help the engine control the fuel-to-air ratio better. The low voltage condition is excessive oxygen in the exhaust or problems causing the issue. Need help with a P0137 code?

What is the diagnostic code for O2 sensor circuit low voltage?

Cost of diagnosing the P0137 code. P0137 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What is the O2 sensor code for bank 1?

All our repairs are backed by our 12-month / 12,000-mile warranty. P0137 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 is failing to increase the voltage output above .21 volts indicating excessive oxygen in the exhaust.

What does low voltage on O2 sensor mean?

Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor’s voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL.
