My daughter's check engine light was on in her 2009 Dodge Charger and the car gave a code of P1004. We bought and new short runner valve and replaced it, had the engine light turned off, the engine light stayed off for a couple of days but it came back on today. What does this mean?

My car has 149000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
The short runner valve actuator that you replaced is just the electric motor that moves the short runner valve to its correct position. However, the problem is likely that the valve itself within the intake is sticking. Using an appropriate spray solvent (carburetor cleaner) you have to spray inside the plenum while turning the valve (tab) back and forth. Eventually it will free up. It’s also possible that the short runner valve harness is open or shorted or that the short runner valve circuit has a high resistance electrical connection. My guess though would be the valve itself is stuck as that is very typical. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a runner control diagnostic repair and cleaning and the responding certified mechanic will get this taken care of for you.

2021 Dodge Charger Check Engine Light Flashing

Other generally common reasons for a Check Engine Light are damaged oxygen sensor, dirty mass airflow sensor, broken head gasket, broken emissions control part, a malfunction with the fuel injection system, or broken spark plugs to name a few.

P1004 – Short Runner Valve Control Performance. Possible causes are a faulty short runner valve assembly, short runner valve harness is open or shorted, short runner valve circuit has poor electrical condition, or your PCM is bad.
If the check engine light in your Dodge starts flashing, that means that the problem needs attention swiftly and your Dodge should be brought in instantly. This blinking light normally signifies a severe engine misfire allowing unburned fuel to be dumped into the exhaust system.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.
The P2015 code refers to the intake manifold runner control (IMRC) system. Most of the time, this is for bank 1, which sits on the same side of the engine as the first cylinder. If your engine is an inline engine, then your vehicle will only have one bank, and this code will indicate a problem with the single bank.
The P2017 code indicates an issue with your intake manifold system. This specific description of “Intake Manifold Runner Position Sensor/Switch Circuit High” means that there`s an abnormally high voltage that the powertrain control module (PCM) has noted in the position sensor of the manifold airflow-control device.
While the check engine light can definitely be indicative of serious problems, the most common cause of the flashing is usually an engine misfire. There are many reasons why an engine misfire might be occurring. To run smoothly, an engine must be receiving the correct amount of power from the cylinders in your vehicle.
A flashing light indicates a more serious problem like an overheating engine or engine misfires, which can cause irreversible damage. If the check engine light is flashing, you should stop, turn off the car, and call for assistance.
The answer is – yes! Worn spark plugs can cause your vehicle`s check engine light to illuminate, indicating an issue. It may even be a flashing check engine light. This is because bad spark plugs can cause your engine to misfire, which will trigger the check engine light to turn on.
p1518 Code – Intake Manifold Runner Control (Stuck Open) | KBB.
The P200A code indicates an issue with your vehicle`s intake manifold runner control (IMRC) system. This is a system within your vehicle that controls the flow of intake air through different routes to the combustion chamber. Changing the flow may improve engine efficiency, which is why the vehicle often does it.
The emissions/exhaust system is the most likely culprit for many check engine lights being illuminated. There could be an exhaust leak or a problem with the catalytic converter. The mass airflow sensor (MAF) is another sensor that is easily tripped or can fail.
A check-engine light will shut itself off if the condition that caused it is remedied. So, if your converter is marginal, and you did a lot of stop-and-go driving, which creates high demand for the converter, that might have turned on the check-engine light.
Clearing the check engine light can cause your car to fail smog. If you`re trying to pass a smog test, clearing the check engine light isn`t a fix. Yes, a car will automatically fail a smog check if the check engine light is on. However, clearing codes won`t make it pass.
The P2015 is generally a minor code without any long term effects once repaired. It should not be a problem to drive to a safe location once the P2015 code has been set.
Code P0443 causes the check engine light to go on and this alone will cause a failed emission test. The code means the fuel vapor system control valve is defective or the circuit to it is not making the connection to the valve so the ECM lost control to the valve.
What the P0404 code means. P0404 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve or sensor is out of specification range or its performance has gone out of specification parameters.
How Serious Is the P2004 Code? The P2004 code can lead to various performance and driveability issues as the engine is not regulating airflow properly through the intake manifold. Moreover, parts of the IMRC can get dislodged and fall into the engine, leading to severe engine damage that can be costly to fix.
The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine.
The OBD-II fault code P1128 is manufacturer specific and is defined as “closed loop fueling not achieved bank 1” for the following vehicles: Dodge. Chrysler. Jeep.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
Intermittent flashing of your check engine light occurs when your engine experiences what`s called either an “intermittent failure” or “soft failure.” Soft failures are caused by engine problems that need certain conditions to appear. The most common example of an intermittent failure is that of broken wires.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.

I have a 2007 dodge ram 1500. Check engine light was on code came up as alternator. Replaced it and the check engine light is stil
ANSWER : Hi there. When an error code is created, it is often stored in the ECU until it is cleared by a professional mechanic during a check engine light inspection. It is possible that this is the source of your error light, especially if you are not having any further problems starting your vehicle.

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 refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

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.

O2 sensors changed, but check engine light still showing code after clearing it I checked fuse. Wires are good and used Denso OE.
ANSWER : Depending on what the code was for will determine if the oxygen sensor was to be replaced. If the conditions were for a rich or lean mixture and it said oxygen sensor, then the spark plugs and wires could need replaced if its a rich reading or the fuel injectors could be clogged or not working if its a lean mixture. If the code said that the oxygen sensor was bad, then check the harness and see if there is a break in the wiring or a short to ground in the wiring from the oxygen sensor to the main harness. If you need further assistance with your check engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.

I Had my oil changed on 5/28/16. On 5/31/16 the check engine light came on. On 6/5/16 the low oil pressure turn off engine came on
ANSWER : Hello,

From what you describe it would not appear to me that something went wrong during your oil change.

If the level is correct on the dipstick and the engine runs and sounds okay, then it is probably something else.

A likely cause for a problem such as this can be a defective oil pressure sensor, or wiring.

Virtually all vehicles have a dedicated oil sensor that will monitor oil pressure of the engine and set off a warning light if it falls to low, in order to protect the engine. If the sensor fails however, it can send a false reading to the computer or gauge, and cause the warning light to activate by mistake.

I would recommend having the vehicle’s oil pressure sensor tested for accuracy, and if necessary the engine’s oil pressure to make sure that there is no issue with the oil pump or system of the engine, as unlikely as that may be.

I’d recommend having a certified mechanic inspect the vehicle for you, they will be able to check for these failures and diagnose your Check Engine Light in order to get your car running normally again.
