Error code P2187

hi guys how are you i hope you doing well
when i was driving my car i felt car was shaking then i scanned the car with obd2 part it gave me error code P2187 and EGR incomplete my car is elentra 2013

excuse me for my bad English i am from Somalia living Saudi Arabia 🙂
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello – the P2187 code indicates a fuel/air mixture that is too lean. This could be caused by a leak in the air intake (the plastic intake tube might be cracked for example), a loose hose on the air intake, or that the EGR valve is stuck open (or not completely closed). Any or all of these can cause a lean condition. With the engine running, spray a bit of starter fluid near any suspected leak. If the engine idle speeds up, you have found an air leak in the intake.

I recommend having a certified mechanic, such as one from YourMechanic, determine why the car is shaking.

The P2187 code indicates that there`s an issue with the air-fuel mixture ratio. Combustion engines typically require a mixture ratio of 14.7+/-2 parts air to one part fuel; if the system notices that the mixture is especially off one way or another, then it will send an error.
Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
when you get that code p2187. it means that you have a fuel system that`s running lean so what that means it means that this oxygen sensor is detecting that you have more oxygen. okay in the exhaust.
Recommended Services. Hello – the P2187 code indicates a fuel/air mixture that is too lean.
It is okay to drive a vehicle with P2187 for a short period of time, but driving with this code for an extended period of time can overheat the engine and cause internal engine damage.
A P0171 code is set by your vehicle`s powertrain control module (PCM) when it detects that the air-to-fuel ratio of your vehicle is too lean.
Tire issues: The most frequent causes of a vehicle shaking while driving stem from tire issues. Tires begin to behave differently when worn or out of balance. Tire replacement, realignment, and rebalancing are common solutions.
One of the main reasons why your vehicle could be vibrating at idle could be due to worn out spark plugs. When a vehicle`s spark plug is faulty, it can interfere with the air-fuel ratio leading to improperly firing cylinders, resulting in a misfire while idling. Replacing your spark plugs will solve this problem.
Vibration is usually caused by an out of balance or defective tire, a bent wheel or a worn driveline U-joint. You may find that the car shakes the car in an up and down motion. You may feel vibration through the seat, the steering wheel or even in the brake pedal.
Code P2191 is a code indicating the engine is running lean on only one side, and this lean condition can cause internal engine damage or cause the engine to misfire.
The powertrain control module (PCM) uses information from the oxygen sensor to determine how much fuel should be injected into the engine. If the PCM detects a lean mixture (too much air versus fuel) in the system, the vehicle`s computer will record a P2191 code on a scan tool.
Error code P0441 signals that your car`s EVP system is experiencing an incorrect purge flow. (Only vehicles with a purge flow sensor or leak detection pump will display this code, so many vehicles don`t list this error.)
The P0507 code is triggered when the Engine Control Module (ECM) detects that the engine is idling higher than the specified idle RPM range. The standard engine idle is usually between 600-800 RPM depending on the model of the vehicle.
A rough idling engine is a clue that some part in your vehicle isn`t functioning properly or may be failing. Besides wasting fuel and other drivability issues, a rough running engine should be promptly diagnosed and repaired to prevent engine damage and ensure your driving safety.
While it may seem like a small problem on its own, rough idling is a sign that some part of your engine isn`t working properly. Over time, rough idling can result in poor gas mileage, starting issues and major engine problems.
Codes P0300-P0399 indicate engine misfire or issues with the ignition system. Here are the descriptions of some of them: P0300: Engine misfire related to multiple cylinders. P0301: Engine misfire in cylinder 1.
Any sensor that measures fuel pressure or airflow can result in lean conditions. This includes the intake air temperature sensor, manifold air pressure sensor (MAP), and the EGR (exhaust gas recirculation) sensor.
If you have codes stored in the engine computer for lean bank 1 and 2 is caused by the entire engine is running lean. This is caused by not enough fuel getting into the engine or too much unmetered air getting into the engine and the computer cannot compensate anymore to run it normal.
You probably know that the answer the questions is — no! A P0171 or P0174 lean code with an O2 sensor reading lean all the time mean — well, several things. The real problem may not be a bad O2 sensor, but possibly be an engine vacuum leak, low fuel pressure or dirty fuel injectors that are causing the engine run lean.
Causes of a lean air/fuel mixture:

A clogged fuel filter will limit the levels of fuel that reach the engine, resulting in a lean running condition. Faulty oxygen sensor – The oxygen sensor (or O2 sensor) measures air levels in the engine.

As you get into the higher speeds, if you distinctly feel vibrating coming from the engine, this could be a result of a lack of power, fuel, or oxygen getting to it. The spark plugs, fuel filter, and air filter should all be checked and replaced as needed.
The source of the problem could be from tires that are not balanced or a worn-out spark plug. It could also be loose lug nuts. A car also vibrates for a number of reasons when you accelerate. Typically it`s from a damaged inner CV joint.
The most common cause of the shaking most often happens near your tires and rims. The tires and wheels connect your vehicle to the road, and if anything is a bit wonky, will notice. It may be something like a broken transmission or a broken control arm.
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.

The TPS error code P0123 appears only when the AC is on
ANSWER : Hello. The low charge in the A/C system is going to cause the A/C compressor to work harder than it should. This will put a greater load on the engine and may cause your throttle position sensor to give a bad reading. Have a certified technician set the A/C system to the proper levels and see if the P0123 code continues. Having the throttle body cleaned may also help fix this problem. If you need help with this, a certified technician from YourMechanic can come to your car’s location to diagnose the code more thoroughly in order to have this corrected.

I have a Code P0601 on the PCM. I replaced the PCM, and now I have a code P0118, code P0123, and code P0193.
ANSWER : Hi there, the short answer to your question is no . A PCM with a P0601 (which is a memory module error in the PCM) cannot reliably retrieve codes for the codes you list (P0118 – coolant temp sensor, P0123 – throttle position sensor, P0193 – fuel rail pressure sensor.

Most likely, the P0601 prevents the PCM from getting any codes from the engine sensors. The memory module error may cause in data corruption for collected sensor values, lose of data over multiple sampling periods, or failure of the data collection to work at all. Replacing the PCM was a necessary expense.

If you need assistance with the "new" codes, I would recommend having a Check Engine Light inspection completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose the new error codes and get an accurate assessment of the repairs needed.

Camshaft position sensor error code P0343
ANSWER : Hello. The P0343 code indicates there is no signal from the passenger side cam position sensor (Bank 1 actually). Given you have changed the sensor, this would suggest a wiring or connector issue. Your mileage would also make me anxious about timing chain guides, tensioner and timing chain – a chronic maintenance item on BMW V8s with this sort of mileage. While the timing chain service is a bit expensive, the alternative is even more so. I recommend having a certified technician from YourMechanic to thoroughly inspect the Check Engine Light and proceed with the appropriate repair.

Check Engine Light is on – codes P0313, P0299, P0304
ANSWER : Hi there. Based on what you’ve described, this could be a combination of faults between 2 or more things; however, I don’t believe the coils and spark plugs are at fault. One of the codes is set during a low fuel misfire (lean condition), one is specifying a misfire on cylinder 4, and one is a turbo related code; all based on a generic code investigation.

The make and model of the vehicle helps, but is not necessary at the moment. When a low fuel pressure misfire is set, there is a lean condition that has been detected by the sensors and one of the codes is telling us in which cylinder this is occurring. A possibility is a restricted fuel injector, loose injector harness, poor pin fit in the wire harness, and an air leak near that cylinder’s port in the intake manifold.

I’m leaning more towards a leak or crack somewhere creating an air leak since we also have a turbo related code stored and an intermittent rough start when cold. I strongly suggest having a qualified technician perform an inspection to determine the root cause. YourMechanic has several available technicians that can assist you with a Check Engine Light inspection and determine exactly what is giving rise to codes P0313, P0299, and P0304.

It threw a code 21 , throttle position sensor bad code. i replaced it and the code went away but i still have no spark.
ANSWER : Hello and thank you for contacting YourMechanic. The problems that you are encountering with your vehicle, could be caused by the harness to the Throttle Position Sensor (TPS) or the computer itself.

Check the harness to the TPS for any debris or any corrosion. Hook up a paperclip to the harness and turn on the key. Use a multimeter and check for voltage at the pins of the harness. Make sure that the ground on the sensor is grounded and has no resistance. If you find that the harness is having too much resistance, then I recommend having the main engine harness replaced. If you have replaced the harness and still have the same problems, then the computer will need to be flashed or replaced.

I recommend having a professional, like one from YourMechanic, come to your home to diagnose your car’s no start condition before replacing any parts.

Can i retrieve CEL code from car … forgot what code it hade in my car .. put headgasket sealer and i erase the code ..
ANSWER : Once a trouble code is erased, it cannot be retrieved. The engine controller does not have a "recycle bin" like they have on Windows. If the car still has a problem, the code will come back up after some driving. However, the controller will not turn on the CEL until it has seen the malfunction on two separate "trips." A "trip" is a driving cycle where the car is started cold, driven until it is fully warm and through a certain number of accelerations, and shut down. So you might not see the CEL for a couple of days. As for the "head gasket sealer," I wouldn’t hold out too much hope of that solving a problem. At the very best it might put off the symptoms for a short while. If you need help interpreting codes that come up, or solving a head gasket issue, contact Your Mechanic. They can send a technician to your home or office to read the codes on your car and help you decide what to do.

I have an error code P2159 popping up on my Hyundai Sonata. I want to know exactly which speed sensor to replace driver or passenger
ANSWER : Hey there. If your Sonata does not have ABS (not sure any exist without ABS), the wheel speed sensor input is from the physical wheel speed sensor, located on the passenger front wheel hub assembly. If your Sonata has ABS (most likely), the wheel speed sensor input is from the ABS wheel speed sensor system – which reads speed from both a sensor in the transmission, and from one or more wheel speed sensors (physical). An ABS code reading tool will be necessary to more precisely identify which sensor is bad. I would recommend having an ABS Light inspection conducted by a professional to pinpoint the fault and move forward with repairs.
