Emissions


Emissions reading high or an Oxygen sensor fault?

Has your car got an emissions problem?

Exhaust blowing – Running problem – Engine Management Light on – Lambda Sensor not working – Catalytic Converter faulty

Autoexperts Medway in Gillingham can carry out a fault diagnosis. Our technicians will carry out some initial basic checks, followed by an engine management fault code read.

Autoexpert’s technicians are able to understand the codes that are retrieved from your car’s ECU. Our technicians will advice you of the best course of action. We can decide what needs to be done to repair your car if it has a high emission reading.

Importance of Vehicle History:

If your vehicle is new to us our technicians will ask you about any history of the vehicle. This may be past faults or simply the service history. This information could be vital when making any decisions on how to repair any problem. Similarly it could affect the final outcome and the cost of repair.

Example 1:

Should a car fail an emissions test the oxygen sensor could have a low reading. Many mechanics will simply advice to replace the oxygen sensor. In contrast our technicians would rather carry out further tests.

If an oxygen sensor’s reading is low it may be because the engine is being starved of air. The engines airways may be blocked. A simple check and replacement of an air filter could cure this problem.

Lack of air in the engine will cause the ECU to alter the amount of fuel being injected. As a result if an engine does not have the correct amount of fuel the engine may begin to give poor performance. In extreme cases it may begin to hesitate. Consequently the lack of fuel will cause a fault code for the oxygen sensor.

Lambda Sensor:

Modern exhaust systems are monitored with an oxygen sensor or lambda sensor. As a result the information from an oxygen sensor is sent to the ECU. A lambda sensor is normally screwed into the cat, downpipe or manifold. The ECU collects the information and adjusts the amount of fuel the engine requires. This helps the engine to run efficiently.

Example 2:

A faulty blowing exhaust will also affect an emissions reading. When our technicians carry out an emissions test the gas analyser probe is inserted into rear exhaust. This allows the machine to test  the car’s exhaust gases. If an exhaust has a blow, it is allowing the gases to escape. This will then give a false reading and could result in an emissions failure.

Why Choose Autoexperts Medway?

Autoexperts in Gillingham have established a superb reputation for high quality services. Refer to our testimonials from our customers on our testimonial page.

When carrying out a diagnosis a partial strip down may be necessary. Should your vehicle be stripped down and you agree to have the necessary work carried out. This initial diagnosis becomes part of the repair and this will probably reduce the overall repair costs.

So when your car’s emissions are high or similarly when a lambda reading is incorrect. Likewise when the Oxygen sensor is faulty or the Cat is burnt out causing the EML to come on. When your exhaust is blowing or you have a general running problem. Call Autoexperts Medway we are the idea garage to use.
