Check Engine Light is on

Around 90k miles had CEL with codes p0313,p0304 car ran poorly and had shop look at it and replaced a coil pack and spark plugs. Around 110k miles CEL returned with p0304 error code returned replaced the other 3 coil packs and new spark plugs. Around 130k miles CEL returned again with error codes p0304 and p0299, I did nothing and reset my CEL. Another 600 miles and CEL returned with error code p0304 I took to shop and they replaced 4 injectors and performed a carbon cleaning. Less than 100 miles CEL returns I do nothing except reset CEL. CEL returns with error code p0313,p0304, and p0299. Whe

Experienced mechanics share their insights in answering this question :

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.

How to Identify and Fix Common car Problems ?

Repairs for a P0299 error code usually include replacing the turbo/supercharger, repairing the intake system, replacing the EGR, repairing low engine oil pressure, or replacing the boost pressure sensor.

What does the P0299 OBD-II code mean? The P0299 code is a generic powertrain diagnostic code applicable to vehicles equipped with a turbocharger or supercharger. When the OBD-II P0299 trouble code triggers, it indicates an underboost condition with either the Turbo or Supercharger “A”, giving excessively low output.

While error code P0304 indicates a misfiring cylinder, the root cause can be many. Your car`s ECM may trigger this trouble code due to a faulty fuel injector, a leaking intake gasket, or low fuel pressure, among other things.

Do not keep driving with this error code. Repair Urgency: Fix this code immediately (same-day if possible) to avoid serious engine damage and dangerous driving conditions. Diagnosis: A multiple misfire can be caused by anything from faulty spark plugs to low engine compression.

You may report a P0304 code if your car indicates a misfire or an ignition or fuel system issue. As a result, it may result in an internal engine failure. This is a significant problem that requires immediate attention.

Many components and conditions could cause a P0299, such as a restricted air filter or blocked catalytic converter.

Possible causes of low boost pressure can be broken hoses, contamination build-up within the turbine or compressor areas, leaking seals, damaged shaft bearings, the wastegate sticking open or operating incorrectly, a leak in the intercooler, a blocked air filter, a damaged diesel particle filter, or a damaged catalytic …

P0324 code definition

When the PCM (powertrain control module) detects an incorrect voltage reading from the knock sensor circuit, it will record a P0324 code and illuminate the Check Engine Light.

– In cold temperatures, ambient and PCV moisture can freeze in the charge air cooler, restricting flow, and causing DTC P0299 and/or P0234.

An engine misfire can be caused by bad spark plugs or imbalanced air/fuel mixture. Driving with a misfire isn`t safe and can damage your engine.

Repairing or replacing a cylinder can range from $100 to $1,000. Different causes for misfires cause different severities of damage that each cost varying amounts to repair. These damages are: Slower fuel delivery issues can cost anywhere from $200 to $1,000.

Misfires don`t simply go away – they need to be addressed immediately. Even if they don`t get worse, they certainly won`t get any better unless you take the car to a mechanic.

What the P0304 code means. The P0304 code will be seen in cars where the ECU has detected that cylinder 4 is not firing properly. The ECU monitors the operation of all cylinders to ensure they are all firing on time, so when one misfires repeatedly, a Check Engine Light is set.

The P0304 engine code can be caused by several things, all of which can be serious and require immediate attention. Ultimately, a cylinder misfire can damage your car engine and result in costlier repairs if left unattended. The main issue caused by misfiring cylinders is damage to the catalytic converter.

While O2 sensors will have a natural lifespan, there are a few things that can cause them to fail more quickly. Contaminated or dirty fuel injectors, engines that burn oil, and even a very dirty air filter can cause O2 sensors to become faulty.

Engine misfires and violent vibrations can be caused by an air filter that is dirty and clogged. The clogged air filter may allow oil to burn improperly, thus contaminating the spark plugs of your engine with excess oil deposits.

Yes, you can still drive your car with a P0299 code, but it is not recommended. This code indicates a turbocharger or supercharger “underboost” condition, which means that the level of boost the engine is receiving is below what the manufacturer has programmed the engine to receive.

Leaks in the plumbing and intercooler can cause a P0299 code and often occur at the couplings between charge pipes. Finding the leaks can be difficult due to the packaging of the intercooler behind a bumper. programming updates. A smoke machine can help find the Leaks in the plumbing and intercooler.

Yes, you`ll still be able to drive your car if your turbocharger fails; however, engine failure won`t be far behind, so only drive on if you have to. As soon as you spot any of the turbo failure symptoms outlined above, you should get your turbo checked as soon as possible by a qualified technician.

Bad Engine Performance

A malfunctioning engine knock sensor can cause the PCM to wrongly adjust the ignition timing, resulting in inadequate engine performance. The engine may not feel right while driving at high speed or when the vehicle is carrying a weighted load.

The P0333 code means that the input voltage from a knock sensor circuit in one of the cylinders on bank 2 is higher than the manufacturer`s limitation. In most instances, a 10% variation is needed for this code to set. However, your vehicle will likely require multiple instances to set the code.

Whether you experience these symptoms or not, here are some typical causes of an error code P0299 problem. Typically, this code is the result of an air restriction or leak in the intake of your engine. Another common cause is a binding turbocharger or simply a faulty pressure sensor.

the boost pressure sensor measures the absolute pressure before the throttle valve. the engine control unit uses its signal to calculate a correction value for the boost pressure.

Engine diagnosis warning lamp activated – The fault code P029921 “The boost pressure of turbocharger 1 is too low.” is stored in the engine control unit. and/or air discharge noise from engine compartment while driving.

p0011 code,check engine light one, changed bank 1 vvt solenoid and check engine light still on?

ANSWER : The P0011 code is typically caused by oil issues with the car. I would particularly make sure the engine oil level is not low. The VVT solenoid relies on proper oil levels to do their job. If they don’t have enough oil, they won’t work. You can have a mobile technician from YourMechanic visit your home or office to inspect the Check Engine Light for you. If you follow through with a repair with us you will be reimbursed for the cost of inspection.

check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor

ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts.

P2196 OBD-II Trouble Code. came and went in 24 hours. 4 starts.

ANSWER : If the mechanic tested the output (functioning) of the oxygen sensor, especially according to the protocol at this link and found that the sensor was non functioning at that time, what you might be experiencing is a "failing" oxygen sensor and so the latest instance of Code P2196 might be explained by that. A complexity though is Code P2196 has many causes other than a failing oxygen sensor including: a faulty fuel pressure regulator; MAF (Mass Air Flow) sensor; ECT(Engine Coolant Temperature) sensor or damaged ECT wiring; leaking or stuck open fuel injector or injectors; and spark plugs and/or coil pack. Basically, if the Code (P2196) recurs, the oxygen sensor output can be re-tested but the mechanic will hopefully be aware of all these other possible causes of that Code setting. If the Code recurs, you can request a check engine light diagnostic and a certified Mechanic, dispatched by YourMechanic right to your location, will get this resolved for you.
