Emission Testing Centers: Everything you need to know

Updated Aug 26, 2021 | Same topic: Automotive FYIs

Get familiar with emission testing with this short guide.

In the mission to reduce our nation’s carbon footprint, the Philippine government requires motor vehicles to undergo emission testing. This was put into law via the Clean Air Act or R.A 8749, which was enacted back in 1999.

As per the aforementioned law, the government now monitors the millions of cars for the gasses they are spewing into the atmosphere. To address this need for emissions testing thousands of emission testing centers are now spread all throughout the Philippines.

Usually, an emission testing center in the Philippines is an open-air facility with two lanes. One lane is for diesel vehicles, and the other is for gasoline vehicles.

But how does car emission testing work exactly? How do I ensure that my car passes the emission test? And more importantly, where are these car emission testing centers located?

How does car emission testing work?

According to the clean air act, these are the emission limits for light-duty vehicles, which include passenger vehicles.

In order to measure the amount of gas pollutants a car spews out, a test center uses a digital exhaust-measuring system. A technician also inserts an OBD-II scanner on your car to gather necessary data that may be relevant to the test.

And lastly, a sensor is also inserted inside your car’s exhaust to measure the quality of the car’s exhaust gases, specifically the amount of Hydrocarbons and CO2 it’s spewing out.

After that, the technicians then starts the car and revs it to a predetermined amount of RPMs simulating real-life driving conditions. The test then finalizes whenever the test machine indicates that it has successfully gathered a reading.

How long does a car emission test take?

The test itself will only take around 10 to 15 minutes. Do note though that there are factors that will cause you to stay for longer at an emission test center. More on that later.

Here in the Philippines, the Land Transportation Office requires a Certificate of Emission Compliance for Passed Testing. This certificate is among the primary requirements whenever you submit your vehicle for registration. The LTO also requires a picture of the car’s rear end during the act of testing with the plate visible so the technicians will also need to snap a picture.

 If your car didn’t pass, you won’t be able to register your car.

Note however that there are many factors that will affect whether your car passes or not. Sometimes, it might be the emission testing machine’s fault due to being un-calibrated, a careless technician, etc. To eliminate the aforementioned factors, we highly advise you to have your emission testing at an LTO certified center.

Car emission testing requirements

As mandated by the LTO and the Department of Transportation (DOTr) in May 2019 through a joint memorandum, all you need is a photocopy of your car’s official receipt (OR) and certificate of registration (CR). You no longer need to bring an original copy.

And of course, you’ll also need around Php 430 - Php 500 for the emission test price.

What causes a car to fail the emission test?

There are many factors as to why a car fails an emission test. The biggest one of which is lack of maintenance. Its oil might be too old and contains more hydrocarbons, the spark plugs might be worn and thus causing inefficient combustion, or your air filter might be dirty. The worst reason of course, especially if the car testing technician uses an OBD-II scanner, is when your car has a check engine light.

A check engine light is also particularly bad because it might be indicating a serious engine problem like a gasket leak. The worst that could happen is that it might be a cracked engine block, cylinder head, piston, or camshaft. The least worrisome is a faulty oxygen sensor.

The bane of all car owners

Barring some fault in your car’s engine, certain car modifications will also cause a car to fail the emission test. This includes anything that affects the air/fuel mixture especially if you gave your car’s ECU a fuel-hungry performance tune.  

Car emission testing procedure

We already covered the actual procedure of the test. Do note though that there’s also a procedure in filing a car to undergo emission testing.

  • The first thing you should do when you get to an emission center is to line up. Typically, these facilities will start operating at around 8:00 A.M. so come early to avoid a long wait.
  • Next, the testing center will provide an agreement form that you’ll have to sign. Sometimes, some forms will require you to enter your car’s make, model, engine displacement, etc.
  • Third, pay for the car emission test fee. Testing centers usually have a counter and a cashier for this. It also helps to bring the exact amount for the fee.
  • The testing center technician will then check your car specifically for things that might cause it to fail the test. Oftentimes, he or she will give you advice on what to do if you do fail.
  • Actual test.
  • Issuance of the Certificate of Emission Compliance for Passed Testing. This might take a while especially if there were other clients before you.
