Where is the O2 sensor on a Toyota p0031?
A P0031 Toyota DTC (diagnostic trouble code) definition:the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is.
What does error code p0031 on OBD-II mean?
If your OBD-II scanner indicates an error code P0031, this means that you have an issue with your O2 sensor number one. For many vehicles, this is also known as an air/fuel ratio sensor. For many vehicles, this is also known as an air/fuel ratio sensor.
What does p0031 mean on bank 1 ho2s1?
The P0031 code is a result of the bank 1 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a seperate heater inside the sensor to get them to operating temperature quickly.
What does the p0031 code on a Toyota heater mean?
The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0031 Toyota code means that the resistance of the heater circuit is lower than normal.

What causes faulty air fuel ratio in Toyota p0031?
P0031 TOYOTA Possible Causes Faulty Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 harness is open shorted to ground Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit fuse Faulty Engine Control Module (ECM)
How to fix a p0031 heater control circuit low bank 1 sensor?
To fix a P0031 Toyota DTC code, you’ll need to do a proper diagnosis. To do that, you’ll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you’ll want to check those as well.
What can cause a p0031 DTC trouble code?
A P0031 DTC trouble code may be caused by one or more of the following: A short or open in the heater circuit in the sensor. A failed O2 sensor heater. Wiring/connectors broken/frayed leading to sensor and/or relay. Failed PCM/ECM.
How much does it cost to repair a p0031 Toyota?
The cost of diagnosing the P0031 TOYOTA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
When to replace O2 sensor on Toyota heater?
On some Toyota vehicles this code is triggered when the resistance of the heater circuit is below 0.8 A. With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #1 on bank 1. Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer).
What causes a Toyota Avalon to lose control?
Cracked or Broken Steering Lock Bar: The steering lock bar wasn’t cast properly on many 2000-2004 Avalons. As a result, it’d crack or break over time, eventually locking the steering wheel and causing the driver to lose control of the car. In 2010, Toyota recalled nearly 375,000 Avalon models to fix this issue.
When to change transaxle fluid on Toyota Avalon?
Every 50,000 miles after 100,000 miles – oil change, tire rotation, brake inspection, coolant replacement (hybrid system coolant if applicable) For 2013+ Avalon hybrid models CARSpec also recommends the hybrid transaxle fluid be changed at 100,000 miles. This is not required maintenance per Toyota but recommended to help ensure proper operation.
When does a Toyota Avalon airbag failure occur?
Airbag Control Module Failure (2003-2004 models only): When an airbag control module failure occurs prematurely, the front airbags, side airbags, and/or seatbelt pre-tensioners deploy unexpectedly.
