Knowing your onboard diagnostics or OBDs is always a better strategy, and it should always be an important priority of your vehicle maintenance.
If the check engine light is popping, one should always take this seriously to avoid consequences or other expenses later down the road.
While a simple light by itself cannot answer all your questions, OBDs are the best guiding tools.
They can read and study a wide variety of code with a product like an OBD scanner which saves your time and resources.
What Is 7e8 and 7e9 Engine Code?
7e8 is great for engine control works, and 7e9 is the transmission managements’ menu only.
Both these codes are not dangerous as such and do not need a cause of worry.
Reading the OBD codes:
All modern vehicles have an On-Board diagnostics system, with which any mechanic can understand the issue of your vehicle.
- The computer has a five-lettered DTC trouble code, always stored, which summarizes the whole issue quickly.
- We can also call them by the name of OBD codes or OBD-III codes.
- One just needs an OBD scanner that can quickly summarise the whole issue from this code.
- The OBD scanner is available and helps in reading these codes.
- The tool works in a handheld position, and it works with a sixteen-pin connector that can interpret the DTC.
- Just plug the OBD scanner into the port, which is mostly right below the driver’s side of the dashboard.
- Turn the ignition on and enter your vehicle identification number.
- Navigate to the codes menu on the OBD scanner and start interpreting one code at a time, starting from the first letter and the second character.
Most popular reasons for CEL blinking in your vehicle:
Check engine light turns on, and we ignore it! This is not something new, and in fact, over 10% of vehicles move with this light on.
- One should not ignore the issue because it might be as small as a gas cap not closed properly to something huge and irreparable.
- Over 62% of all the problems related to this issue are due to only twenty parameters, out of which some are quite common than others.
- As per the data from Vehicle health report 2017, issues such as faulty oxygen sensors remained one of the major behind CEL.
- So, check for its error code, or if it is blinking red and showing an emergency, then better you stay cautious.
A recommended item:
Think car OBD2 Scanner Code Reader for Car – $130.44 to $154.90
- ABS/ SRS and Engine complete OBD reader with Wi-Fi update and 28-reset.
- Read and erase any faulty codes easily, and it works on more than 1000+ car makes.
- It comes with a big five inches touch screen and Android 7.0, which makes it portable.
- It supports a wide plethora of languages and generates a general automobile health report as well.
- A recording is available for those important data securities.
Some other questions,
Related Questions and Frequently Asked Questions (FAQ):
Q1.) Why is code 7E8 special for engines?
Answer: The code means that fuel/air intake is taking place. Similarly, code P1326 happens whenever the knock sensor detects any wide range of vibrations on the knock engine.
Again, there can be a faulty setting of this sensor leading to incorrect logic picking up by this sensor.
Q2.) What is the meaning of engine code 7EA displays?
Answer: To answer in one word, Nothing dangerous! Mostly, the OBD scanners will put this code forward if they require some basic info.
Again, faulty sensors and lights coming up are also not new.
Q3.) Can I clear all my codes by just disconnecting the battery?
Answer: Yes!
Let the battery stay for around fifteen minutes in disconnected mode, and this will reset all the settings on reconnecting the same.
This will also clear all error codes for you and reset the engine light.
Q4.) What are some of the most common faulty check engine lightning?
Answer: Well, there are many to choose from, but the faulty oxygen sensor is the leading among them.
The sensor is responsible for optimizing the automobile’s fuel-to-air mixture and its mileage.
Loose fuel cap or catalytic converters sensors also give faults a lot.
Q5.) What do you understand by the KWP2000 code?
Answer: Nothing serious!
It controls the communication protocols for all on-board diagnostic issues.
Today, many of the top Auto-diagnostic tools depend upon KWP2000 for reading and analyzing the data to the vehicle’s ECU.
Q6.) How can one differentiate between the OBD & OBD2?
Answer: OBD 1, in which we connect to our vehicle, and the onboard diagnostics II is quite modern and can connect to the same thing remotely.
Lastly, OBD I came during the beginning years of automobile manufacturing, while OBD II became popular during the 1990s.
Q7.) What type of OBD runs in your car?
Answer: If your automobile came after Jan 1, 1996, then it is the OBD II as per the US rules.
And just to double-check the same, check for OBD II compliant stickers on your vehicle.
Q8.) Will OBD II get disconnected or reset if I reconnect my battery?
Answer: No!
While you will get a reset, but this does not promise that all fault codes will evade by themselves.
This is because the engine control units are still able to catch those fault codes as they can draw electricity from the capacitor itself.
So, you need to get rid of this power as well to do a complete reset.
Q9.) Is there any way that we auto-reset the engine light?
Answer: Yes, it is going to automatically do it, provided the problem gets okay.
Make sure the problem resolves, and you are good to go for most parts because the same light will repeat itself after a certain number of cycles.
Q10.) How much time will it take to recheck the CE light after you reset it?
Answer: A check engine light will take over one hundred miles before giving off any genuine result because this is the time the computer needs to program what sensors are sending.
Q11.) Can we touch both terminals and battery cables to reset the computer?
Answer: Yes!
By just touching them together and unloading the capacitor, everything will need a reset.
From clocks resetting to FM stations and to fault codes clearance, the temperature will be relearnt, and so is the security codes.
Q12.) Can I remove the positive terminal of the battery first?
Answer: No!
Only do this as a yes from us if you want to risk electrocuting yourself or hurting your surrounding area.
Otherwise, as a rule of thumb, one should always disconnect the NEGATIVE TERMINAL of the battery, then the positive.
Q13.) How can I reset the car radio without any codes?
Answer: Begin by turning on the ignition to ON.
Then go and switch on the radio; if it shows CODE or LOC, shut it off.
Then, just press and hold your Audio + Power buttons combo with a SEEK button for around fifty minutes, and you can enjoy the radio without a single code.
Q14.) Can I ignore the check engine light as on and keep on driving my car?
Answer: No!
As per a thumb rule, if one understands something clearly at last flashing on and off, immediately stop the car because it means the engine misfires rapidly.
The most common damage you can do is to the catalytic converter, and that too is an irreversible one.
Q15.) What do assorted colors of light mean for the check engine light?
Answer: It can have many meanings. For instance, a yellow light indicates that you should take the problem seriously or start investigating it sooner.
Red means do not waste time and stop at present.
Q16.) What is the k-line in a vehicle?
Answer: It is a communication window but at a low speed and a single wire cross-connection between the ECMs or electronic control modules.
They also assist with onboard infotainment.
Q17.) Why, despite my engine light being on and still nothing feeling wrong?
Answer: In other words, your car is driving great despite the light blinking.
The light does not always show an underlying issue with the engine because the problem can be as mediocre as someone forgetting to tighten the cap of gas.
Interestingly, this is the most common reason.
Q18.) How to read the OBD codes by yourself?
Answer: Buy an OBD scanner!
Then plug it into its place near the OBD port and turn on the ignition as well immediately.
Then, enter the VIN and OBD codes into the menu and interpret them character by character.
Final Verdict:
Modern vehicles have smart onboard diagnostics facility that makes it a breeze to get your hands on the underlying issue.
But also makes it complicated for the user due to a plethora of faulty codes, which can be really frustrating at times.
More than 10% of US citizens do not bother about any issue like check engine light blipping or red light on their dashboard.
They use the OBD codes to store the issues, and only an OBD scanner can reveal them; that is why we recommend them as well.
This is because there is a plethora of OBD codes to remember that one just cannot remember as there is no need to do so.
So, drive safe for you and others as well
