Honda Check Engine Light Codes

Welcome to the Honda Check Engine Light codes page. Below you will find the most complete list of Honda trouble codes available. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? We have a large number of resources to help you repair the problem. Here is how we suggest you proceed. Look up your code definition. This tells you where to start testing. If you are unsure of any abbreviations, check out the acronym list by clicking on the link at the left.

Next, read our article Automotive Circuit Testing 101, and if there is an article related to the system you are testing, such as Oxygen Sensors or EGR concerns, read these as well. They will provide valuable info! If there is a link to a specific diagnosis strategy for the code then follow that and start testing. If there is no procedure for your manufacturer specific code, then I suggest referring to a similar generic OBD II code (these are listed numerically by system type) to get a good idea of what to look for. If at this point you still need assistance use the «Get Help» link and let us know how we can help. We can provide information on component location, specifications, circuit color/location and more. We do ask that you please read the info available on the site first so that we can help reduce repeat questions. So please read our Disclaimer and when you’re ready jump in!

We do our best to update these Honda check engine light codes as frequently as possible. If you find one missing let us know and we we’ll add it immediately! Please use the form on our Contact Page to get in touch with us. We certainly understand how frustrating it can be to look for a code definition and have it not online when you need it. And lets face it, if the service engine light is on then you need it now! It’s easiest to use the «Find On This Page» feature of your browser’s «Edit» menu to find codes on this page as the list is quite long. These are listed in numerical order for easy searching.

When retrieving Honda check engine light codes with an OBD II scan tool, proceed as follows: 1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the glove compartment. The connector has a removable cover. 2. Turn the ignition on. 3. Follow scan tool manufacturer’s operating instructions to access the Diagnostic Trouble Codes (DTC’s).

You may also retrieve Honda check engine light codes using the Malfunction Indicator Lamp (MIL), by counting the flashes as follows: 1. Connect SCS service connector special tool No. 07PAZ-0010100, or equivalent, to service check connector located under the passenger’s side of dash. 2. Turn the ignition on. 3. MIL will indicate DTC’s by outputting a number of flashes.

Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other Honda diagnostic trouble codes.

Honda CR-V: Flashing Check Engine Light Diagnosis

A flashing check engine light is your Honda CR-V’s way of saying “I have a serious problem, don’t ignore me”. Most of the time, that serious problem is a misfire. This flashing light should not be ignored. When your engine is misfiring, it is dumping raw fuel into the exhaust. This raw fuel can detonate, which causes damage to the catalytic converter and the exhaust system itself.

There can be other situations that can cause the check engine light to blink as well. It’s flashing to let you know that if you keep driving the vehicle, you are going to ruin the catalytic converter and/or damage the engine in a meaningful way.

Fuel System Issues

Keeping in mind that any engine needs air, fuel, and spark for ignition, your Honda CR-V’s fuel system can often cause the engine to misfire. It can run too lean or rich. Alternatively, there may not be enough fuel for proper combustion, or the fuel isn’t atomizing properly.

  • Fuel Mixture: If the engine is running rich or lean, the engine will misfire and throw the fuel mixture related codes, such as P0171, P0172, etc.
  • Injector Issues: A bad fuel injector(s) can cause a misfire. If the fuel can’t atomize properly, the engine will misfire. Here’s a good article on how to diagnose whether your fuel injectors are bad from procarmechanics.

Blinking Check Engine Light Diagnosis: Honda CR-V

There will always be trouble codes associated with the check engine light blinking. These trouble codes will be able to tell you where to start hunting down the problem. Here are the most common issues that end up causing the check engine light to flash. But, follow the OBDII codes. A code scanner is cheap. Use it to find out exactly why your vehicles computer decided to flash this light.

Other Issues: Flashing Check Engine Light- Honda CR-V

While a majority of the time, the flashing check engine light is going to be caused by a misfire related to your CR-V’s ignition system or fuel system (as stated above), there are other issues that can cause it.

  • Your timing chain could have jumped.
  • If you have VVT, it may be having issues.
  • EGR- The EGR system recycles burnt exhaust gasses back into the combustion chamber.
  • Crank/Cam Sensor- When the cam or crank sensors are not being read by the ECM/PCM, it’s impossible to get the ignition timing right. If you CR-V does start at all, it’ll run rough.
  • It could be a more serious mechanical issue, such as as bent valve, bad lifter, etc….

CR-V Check Engine Light Flashing Due to Ignition Issues

The ignition system is the most common reason that the check engine light will flash. The ignition system consists of spark plugs, plug wires, and the ignition coil packs (older vehicles have a distributer that has the same function as coil packs). These parts work in concert to ignite the fuel in the combustion chamber at just the right time.

  • P0300: Random Multiple Misfire– This is one of the most common codes that is thrown when the engine is misfiring. It means that the engine has a misfire, but the computer can’t detect which cylinder that it’s coming from. This code is often thrown when there is a fuel issue, or a timing issue, and not just bad ignition components. That is unless all the cylinders share a common coil (distributor ignition).
  • P0301-P0312: Cylinder Specific Misfire- These trouble codes correspond with a specific cylinder misfiring (cylinder number corresponds with its place in the firing order). Although it’s a bad sign when the service engine soon light flashes, when one of these codes comes up with it (and nothing else), it’s almost always one spark plug or ignition coil. There can be other reasons this code is thrown, you can see more by clicking on the P0301 link above.

There are other misfire related codes as well, but those are the most common ones.

Conclusion

We recommend that you don’t drive your vehicle if at all possible until you diagnose and fix your CR-V’s flashing check engine light. Just pretend that it’s letting you know that it’s going to cost you way more money to fix the problem if you keep driving it.

Honda CR-V P0420 OBDII Code Defined

P0420 is a OBDII trouble code. The code technically stands for:

Catalyst System Efficiency Below Threshold

Your CR-V has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.

READ  Какой антифриз заливать в Honda аккорд

When the readings from the upstream and downstream oxygen sensors show similar readings, the vehicle will throw the service engine soon light (P0420).

The software in your vehicle believes that the catalytic converter is no longer doing its job.

If your vehicle has the P0420 code, it won’t pass emissions so please be aware of that.

Top Causes of P0420 in the Honda CR-V

There are many things that can cause the P0420 trouble code in your CR-V. Here are the most common ones.

  • Oxygen Sensor– The P0420 codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings. When the oxygen sensor is bad, it can cause a false reading and trigger the code. If the engine does not exhibit any of the decreased performance associated with a bad catalytic converter, it very well may be the oxygen sensor (if you haven’t noticed the performance loss yet).
  • Catalytic Converter– A catalytic converter is responsible for scrubbing out as much pollution as possible from the CR-V’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.
  • O2 SensorWiring– Over time, the oxygen sensor wiring can go bad. It is especially volatile since it is right next to the hot exhaust at all times. The downstream oxygen sensor wiring is especially volatile since it is so far from the ECM (more distance to travel.
  • CR-V Timing– If your CR-V is misfiring or the exhaust timing is off, this can affect the gasses that are actually going to the O2 sensors enough to cause the P0420 code to register.
  • ExhaustLeak– If there’s a noticeable exhaust leak coming from the vehicle it can change what the O2 sensors register enough to throw the P0420 code.
  • Engine Temp Sensor– If the computer doesn’t know what the engine temp is it’ll keep the fuel mixture rich. When the fuel mixture is rich, the exhaust the O2 sensors see will be out of range and it could throw the sensor.

Honda CR-V P0420 Code Symptoms

The P0420 code in a Honda CR-V will often be thrown one of your oxygen sensors are not functioning properly. Typically, the code will be triggered by the upstream oxygen sensor (before the converter).

There aren’t usually any drivability issues associated with P0420. For most people the first sign that anything is wrong at all is the service engine soon light coming on.

Here are the typical symptoms that something is wrong when you have code P0420.

  • Mileage- May or may not suffer depending on how much the catalytic converter is clogged.
  • Loss of Power– It is a really strange feeling to drive a vehicle with a catalytic converter that is going out. Typically, they’ll idle ok and drive normal under a light load. Whenever the engine is put under a heavy load it’ll feel like it is running out of gas. It’s very similar to the symptoms of a bad fuel filter.
  • Service Engine Light– Often, this is the only symptom of the Honda CR-V P0420 code.

P0420 Honda CR-V

This page is meant to help you troubleshoot the Honda CR-V P0420 trouble code. It covers Honda CR-V P0420 meaning, symptoms, causes, and possible solutions. In the CR-V, OBDII P0420 is often caused by a bad oxygen sensor, but there can be other causes as well.

One of the most common trouble codes with all Honda vehicles is the P0420. This code number references a number that is given to you when you plug your Honda CR-V into a OBDII scanner. It doesn’t matter which model you have, this OBDII code has the same meaning for all of them.

P0420: Catalyst System Efficiency – Below Threshold

Honda CR-V P0420 Code Possible Solutions

Often, the oxygen sensor is the cause of P0420. Specifically it’ll usually be the O2 sensor(s) on the upstream side of the catalytic converter.

But, don’t be surprised if it’s not. It would be a good idea to check the exhaust for leaks first. You should be able to hear an exhaust leak easily underneath of the vehicle.

Unless you have an exhaust leak, you’ll probably need to test the O2 sensors and/or catalytic converters. Here are a couple of good guides to help with that.
