The vehicle verification in CDMX returns on July 2, and here we give you 6 easy points to review to make sure that your car will pass without problem.
Before, users came to checkpoints confident, almost certain that their car would pass the test as long as it had the stipulated age. Not anymore, with the new program the rejections have increased and sometimes the reasons are as simple as they are easy to amend. Searching to buy used Honda Accord VTEC online?

Remember that with your payment you have the right to two attempts, so if you are rejected the first time it is important that you review the following points before taking your turn again if you do not want to be rejected again and then yes, have to pay again the fee.
Check the Witnesses
It is one of the main reasons why cars do not receive the ‘0’ decal since any warning light related to the engine that is on at the time of verification will cause rejection, even if said warning does not appear to be important or if it does not reflect the actual condition of the car.
For example, for cars that warn about maintenance intervals, it is very important that you check if the central display does not indicate that it is close to service and also that you ask the workshop or dealer to reset it after having performed the maintenance service correspondent.
Waters with the Muffler
It is a somewhat silly cause, but it is well worth mentioning. As cars age, certain harmful particles may remain in the tailpipe and build up over the years.
When the operator of the verification center inserts the probe to measure emissions, it will register all those stored particles and will assume that they are emitted by the engine at that moment, so your car will be rejected and you will have to try again.
It does not matter that your engine is in excellent condition and that its actual emissions are much lower, so it is convenient that, with each maintenance, you ask your dealer or workshop to clean this area of the car as much as possible.
Make sure the Oxygen Sensor is Active
It is the most common failure, and one of the main complaints from users with new cars. The thing is like this, when the car rolls its first kilometers the oxygen sensors and their connection with the OBD are not activated at the moment, but for a few kilometers you’re driving and acceleration habits are ‘learned’ to adapt to the environment of the vehicle. Best possible way.
During this period of time, if you take your car to the verification site, the computer that receives the information from the car will not be able to establish a connection and will assume that something is wrong with your car, even if it is practically new and is in the best of conditions terms.
We suggest that you ask the agency how to proceed with the first verification of your car so that the service personnel can guide you in this regard, since the parameters for each brand are variable and depend on the configuration of each manufacturer.
Supposedly, you should not have conflicts checking after 500 kilometers, but if you do, your dealer must assist you at no cost.
High Carbon Monoxide Emissions
It’s the reason why more cars are rejected every day, and it doesn’t necessarily involve overly expensive or complex mechanical failures. The root is that there is more air than there should be in the combustion chamber at the moment of ignition, but this can be corrected with a check in your workshop since generally the specific cause is a dirty oxygen sensor that is not correctly detecting the amount of air and therefore injects less gasoline into the cylinder. A checkup or cleaning is not excessively expensive or time consuming.
High Concentration of Hydrocarbons
As such, your car’s emissions contain a large percentage of unused gasoline, which will also bring higher fuel consumption than expected. All modern engines inject slightly more gasoline into the engine than is necessary, and the portion that does not ignite is used to cool the engine to keep temperatures under control.
If even more gasoline is injected, this is when the concentration increases to illegal levels and the car is rejected. Generally, the root of this problem is that your spark plugs are in bad condition and your car already requires a tune-up or they are just dirty, but in both cases the solution is relatively simple.
Another reason for this failure is that the gasoline is contaminated with a secondary component, which could well be water. In this case, the repair is more expensive since you will have to remove the fuel tank to drain it along with the entire injection system and replace all the spark plugs.
OBD Connector Failure
A reason that may not be common, but is so simple that it is worth mentioning just to make sure that this is not why your car does not pass. As with our mobile phones, it is possible that one of the pins of the OBD socket is dirty and not detected when carrying out the process.
However, every time you take your car to one of their maintenance services a scanner is connected to it and if your service advisor does not tell you anything, it is very likely that there is no problem in this regard.
