Without a scanner or code reader, there are numerous ways to access a check engine light code or multiple codes. Nevertheless, the method you use will depend on whether your car produces OBDI or OBDII errors.
Let’s look at a few ways to get your car’s codes:

Step 1: Turn The Ignition Key
Without starting the car, turn the ignition key ON and OFF. Repeat this process several times—usually three to five—while being sure to cease switching your key to the ON position.
Your car’s model will determine how many times you need to crank the ignition key.
But there’s a quick trick you can use. If all of the dashboard’s lights are on behind your steering wheel, you can cease turning the ignition key.
Not to worry if you accidently start the car. Simply restart, and your vehicle will search for any previously saved check engine light codes.
Step 2: Check Your Dashboard
Except for the service engine light, all of the dash lights will go out immediately after they turn on.
If the engine light codes appear on the odometer, make a note of each error code (DTC). Most modern cars or cars with the OBDII system can be repaired using this technique.
However, if your check engine or service engine light starts to pulse or flash instead of the odometer display, your car is OBD1. And your fault code is the flash that the engine light produces.
How do you interpret the code? It can be challenging to read a code from a check engine light blink.
Each engine light pulse corresponds to a digit, and the pause between pulses shows how far off the digits are from one another. A brief engine light flash serves as the representation for a zero.
Without a Nissan, how can I verify the code on my check engine light?

Press the accelerator pedal all the way down and hold it there for at least 10 seconds. The backup memory in the ECM has been cleared of the emission-related diagnostic data.
3 Note:
The DTC will disappear from the backup memory in 24 hours if the battery is unplugged.
Note:The list that follows is not exhaustive; parts of the code may change depending on the model. Please refer to the section titled “Engine Control”
How can I view check engine light codes?
Check Engine Light When a problem is found with one of your vehicle’s monitored systems, a light will illuminate. You must read the codes through the OBD port in order to determine why the light is on.
A tool to scan the OBD is required. You can talk to the computer and get the error codes via the scanner. Some scanners may provide information on the meaning of the decoded code, while the majority only provide a five-digit number and letter combination.
To insert and read the OBD scanner, carry out the following 4 steps:
Step 1: Find the OBD port on your car. The most typical place to attach an OBD port is underneath the driver’s side of the dashboard, close to the pedals.
Legally, it must be located no more than three feet from the steering wheel and be unlocked.
Put your OBD scan tool into the connector in step 2. There is only one method the male end of the scan tool may attach to the connector on the car.
Read the computer’s codes in step three. Read your scan tool’s instructions carefully since they will vary depending on the model.
Step 4 is to write down the codes that appear. If there are numerous codes, you might have to push a button or they might cycle through before you can see the next code.
- Note: It’s crucial to record these codes in the exact order as they appear on the scanner. However, when your scanner is connected to an OBD port or data link connector, the OBD codes will always display on your scanner (DLC).
Can I use my phone to scan my OBD2?
Although the majority of Android scan tools support all five protocols, this does not mean that every device is compatible with them. However, why pick an Android scan tool? There are numerous advantages to this:
- The popularity (or market share/dominance) of Android versus iOS is a hotly contested topic. According to a recent survey from 2015, Apple had a staggering 44% of smartphone subscribers, outpacing the combined subscribers who purchased Android-powered handsets from Samsung, LG, Motorola, and HTC. However, Android is still widely used in the US and is far more prevalent abroad. Worldwide Android shipments in 2003 totaled 70.1%, vs just 21% for iOS. There are no valid arguments as to why Android Bluetooth scan tools are still in demand today.
- As we’ve already noted, the great selection of OBD apps available on Google Play makes it feasible for OBD2 scan tools for Android to be incredibly simple to use. You can use certain free apps, but in order to access all of the in-app features, much like the majority of Play Store games, you must purchase the paid version of the app.
- Android is seen as a universal platform, much like Windows for the PC, thanks to its plug-and-play characteristics. Both Bluetooth and Wi-Fi OBD2 scanners can be used with Android smartphones and tablets. We are all aware that Apple and iOS are Bluetooth-incompatible and can only be utilized with Wi-Fi wireless OBD2 scanners. Why? We can all blame Apple for this because of their stringent wifi and sharing restrictions.

However, there are two dashboard lights that you should avoid driving to for a free inspection.
- The overheating light is one. Your motor is overheated and low on coolant if the thermometer is red (or has a leaking head gasket, where coolant is running into the oil).
- The red oil-can light is number two. This indicates that your oil is critically low.
You won’t find a comprehensive diagnosis at an auto parts store, of course, if you want one performed by an ASE-certified car mechanic.
However, to avoid wasting money, it might be worthwhile to try them for simple problems.

What is the Nissan Altima’s most typical issue?
The Altima’s continuously variable gearbox is where the majority of its issues lie (CVT). Owners complain about a shuddering or jerking sensation when accelerating as well as a delayed throttle response. Transmission failures have even occurred in some models.
What does the Nissan Altima’s check engine light mean?
Your 2020 Nissan Altima’s check engine light will begin to blink if there is an urgent need for repair, so you should bring your Nissan in right away. Usually, a serious engine misfire that causes unburned fuel to escape into the exhaust system is indicated by this blinking light.
How can I see whether my check engine light is on?
Reading the check engine light code that the car’s computer system provides is the first step. These are the details that your engine’s sensors have recorded. OBD II scanners or readers can read it using a connection (OBD port), which is often found under the steering column.
There are three ways to understand the code:
1. Pay a diagnostic fee and have your automobile serviced by a professional. If you agree to have the required service performed at that garage, the charge is frequently eliminated.
2. Take your vehicle to an auto parts store so the code may be read gratis. The benefit of the free check engine light analysis is that you might even be able to fix the problem yourself if the code turns out to be for a small issue.
3. Purchase a cheap scanner and decipher the code on your own. This is an especially wise choice if you drive an older vehicle that occasionally displays the check engine light due to minor issues. Scanners start at around $15, and some of them can wirelessly transmit data to your smartphone.
How can I tell if the check engine light on my car is serious?
Whether the check engine light is steady or flashing, its significance can change.
An issue has been discovered when the engine check light is both solid and flashing. But if your engine check light is flashing, there is a significant issue that needs your immediate attention. To avoid severe damage, it is best to call a professional as soon as you notice a flashing light.
When a situation is critical, the engine light may not blink in some automobiles. If an important problem has been found, red or orange will display in place of yellow on the light.
Bottom line: Whether the check engine light is solid or flashing, you should always have your car diagnosed and fixed. A flashing light signals an urgent situation that need immediate attention. Seek a mechanic’s assistance as soon as you can to protect your car and avoid having to make expensive repairs.
AutoZone is able to read obd2 codes.
