Description

OBD-II Trouble Code Description for P0136 Subaru

O2 Sensor Circuit

What does this mean?

OBD2 Code P0136 Subaru definition:
Essentially the same as P0137 Subaru, a P0136 Subaru code definition:the second oxygen sensor on Bank 1. The O2 oxygen sensor produces a voltage between .1 mV and .9 mV. The ECM monitors O2 sensor voltage and determines if exhaust is lean or rich. O2 sensor voltage is high when exhaust is rich and low when exhaust is lean. The ECM monitors this voltage and increases or decreases fuel injector pulsewidth according to engine fuel/air ratio. If the ECM detects low HO2Sensor voltage for an extended period, it will set P0136 Subaru Conditions required to set: HO2 sensor voltage is low for longer than 2 minutes (minutes depend on model of vehicle. Could be up to 4 minutes)

Symptoms

Possible sumptoms of OBD code P0136 Subaru
There may be no visible symptoms to the driver. Poor fuel mileage, possible misfire, depending on O2 sensor position when sticking.

Causes

Possible causes of OBD code P0136 Subaru
A code P0136 Subaru may mean that one or more of the following has happened: Faulty O2 sensor leak in exhaust close to O2 sensor Short to voltage on O2 signal circuit Open in circuit resistance caused by corrosion in connector

Possible Solutions

Replace the second oxygen sensor on bank 1 Repair open or short in signal circuit Clean corrosion from connector
