Can You Clean An O2 Sensor With Brake Cleaner

Cleaning O2 sensor

How to avoid the need to replace the Oxygen sensor

1 - The role of the Oxygen sensor

The o2 sensor (oxygen sensor) is located within the exhaust arrangement, upstream of the catalytic converter.

Its function is to inform the ECU of the oxygen content of the burned gases that result from combustion. The o2 sensor helps to ensure that the amount of fuel injected into the cylinders for the air-fuel ratio is at an ideal level.

The o2 sensor ensures low fuel consumption as well as reduced pollutants emitted from the engine. It is therefore an important component to assistance laissez passer vehicle inspection.

The latest standards of emissions require the presence of a second lambda probe, located afterwards the catalytic converter in order to determine its effectiveness.

2 - Why supplant a Oxygen Sensor?

A faulty oxygen sensor has the directly upshot of disrupting the engine air-fuel rest. This leads to an increase in pollutants emitted by the engine, as well every bit causing the engine to stutter and consequently fuel consumption to increase.

iii - When does the Oxygen Sensor need to be replaced ?

The lifespan of a Oxygen Sensor is 160,000 km on average, equally long as it is not shortened by engine malfunction.

Unburned oil due to engine misfire may contaminate the probe irreversibly. Exhaust leaks also impairment the Oxygen Sensor, leading to an intake of air which tin can cause a dangerous increase in temperature.

To ensure the maximum lifespan of the Oxygen Sensor, it is necessary to perform strict engine maintenance (spark plugs, air filter, et al.).

Several signs that your Oxygen Sensor needs to be replaced:

- If the engine cheque light turns on while the vehicle is being driven.
- The engine stutters and suffers from a lack of acceleration ability.

Diagnosis of the Oxygen Sensor

A lacking oxygen sensor is detected only by a special diagnostic tool used by trained professionals. It is therefore necessary to have this service administered at a professional person garage.

		Status of the Oxygen Sensor : Dark brownish saturation Possible crusade : Unbalanced air/fuel mixture
		Condition of the Oxygen Sensor : Grainy green saturation Possible cause : Anti-freeze leak that has entered the combustion chamber
		Condition of the Oxygen Sensor : Reddish or white saturation Possible cause : Additives in the fuel
		Condition of the Oxygen Sensor : Blackish with oily saturation Possible cause : Besides high oil consumption

How to clean the O2 Sensor

There are 2 means to clean or supervene upon the oxygen sensor, falling within a broad price range.

The most expensive option is the outright replacement of the part. This is what most mechanics will propose. The toll of the component varies according to the make and engine type.

The least expensive option , with no need for disassembly and entailing the shortest service fourth dimension, and which is an culling to part replacement, is hydrogen treatment via the Carbon Cleaning station. This service works as a preventative treatment, recommended every xv,000 miles, but can too resolve existing bug in the engine.
