P0206 and P0207 showing up
07 Audi, runs, drives good, no vacuum leaks, and have p0207 and p0206
Experienced mechanics share their insights in answering this question :
Hello the codes P0206 and P0207 indicate faults in the fuel injector circuitry for cylinders 6 & 7 respectively. It means the engine management computer detects an electrical fault. This may simply be a bad electrical connection, or failure in the works, that has not yet affected how the engine runs. Engine management software also "interprets" feedback from the coil and spark plug for each cylinder, and O2 sensor, to evaluate combustion for each cylinder. Problem codes like this can be set for something that is not an absolute measurement or failure, but rather a perceived problem. Check the electrical connector for all injectors and the ground connections. If the engine starts running rougher, I would recommend having a car is misfiring inspection completed by a professional mechanic, such as one from YourMechanic, to diagnose this problem, get an accurate assessment of damage, and give you an estimate for repairs.

Possible Fixes
Check the wiring to the injector for loose connection, damage or corrosion. Perform a wiggle test. Using a multimeter, check the resistance of the injector. If this doesn`t fall within spec, it may be the injector itself.
An open or short circuit in the fuel injection wiring can trigger the P0206 code.
P0306 is for a misfire. Replacing your plugs and ignition coil most likely fixed this. P0206 is an injector fault, or faulty wiring to the injector. As you have been working on the engine i would look for a loose wire to the injector, as you have probably misplaced it when changing the plugs.
A defective fuel injector or a problem with the circuit itself are both very common causes of these codes. In some cases, you might see an issue with the PCM or a problem with the battery voltage, although these will usually cause other codes to fire and are less common.
What the P0206 code means. When a P0206 code is seen, the Engine Control Module (ECM) has detected either voltage or resistance that is out of specification in the fuel injector circuit for cylinder 6.
Poor fuel quality —The main reason your fuel injectors become clogged and unable to do their job is the quality of your fuel. If your fuel has too much excess debris or impurities, those by-products can get into your fuel injectors, making it harder for them to work.
Code P0306 can occur for various reasons, including a malfunctioning ignition system, fuel system, or internal engine failure. The most typical cause of this is faulty or worn-out spark plug coil packs. It happens if you haven`t had a tune-up in a while.
What the P0307 code means. When the P0307 diagnostic trouble code is stored by the Powertrain Control Module (PCM), it is an indication that a misfire has been detected in cylinder 7. More specifically, the PCM detects an increase or decrease in crankshaft revolutions per minute (RPM) that exceeds 2%.
A faulty fuel injector can cause the vehicle to experience misfires, a loss in power and acceleration, a reduction in fuel efficiency, and in severe cases can cause stalling or prevent the engine from running at all.
Finally, as we touched upon briefly above, clogged or leaking fuel injectors can cause your engine to misfire. You will notice the sputtering when you press down on the accelerator and while you are in motion. You will also feel your vehicle vibrate because your engine is misfiring while you are sitting at an idle.
Poor fuel quality —The main reason your fuel injectors become clogged and unable to do their job is the quality of your fuel. If your fuel has too much excess debris or impurities, those by-products can get into your fuel injectors, making it harder for them to work.
Fuel injectors typically fail due to a buildup of contaminants such as carbon. Carbon build-up can cause a clogged or partially clogged injector, preventing the injector from closing all the way. This results in a drip that creates a misfire.
The problems that trigger the P0270 code are commonly caused by the following issues: Faulty fuel injector. Clogged fuel injector. Failed PCM.

Toyota Tacoma (05) cabin air filter. Two videos show the arrow should be pointed up, two show it should be pointed down. What is
ANSWER : It looks like the arrows on your particular cabin air filter should be installed with the arrows pointing downward. Just keep in mind that the arrows are meant to show which way the filter is installed so that the arrows will point the same way as the airflow through the box. I hope this helps.

I installed a new fuel sending unit the gas tank is full and it shows empty when u take all gas out it shows full what could it be
ANSWER : It sounds like you put in an incorrect sending unit or it is defective and needs a replacement. The fuel sending unit will vary resistance from low to high resistance controlling the gauge. If the signal from the sending unit is opposite of what it should be then the gauge will work opposite of the way it should. I would recommend replacing the sending unit and make sure the new one works opposite of the one you have now. You may have to get the correct one from the dealer since sometimes the aftermarket ones do not always work. You can connect the sender and check it before installing it back in the tank.

The back-up camera on our 2011 Ford Edge shows shows images upside down or a blank screen 50% of the time. How do we fix this?
ANSWER : Hello, thank you for writing in. Issues like this are typically related to electrical issues, or programming issues. Both can cause you symptoms, and similar problems. In these situations, there may be several things you have to try until you find the problem. Start with the easiest and cheapest solutions researched first, and work your way up in complexity and cost. Begin with accessing the camera’s settings, and attempting to get the camera’s program to catch up with itself. This has to be done when the camera is malfunctioning. You can then try to reboot the system via the controls, or unplugging it for 20 minutes. You may then want to turn to updating the system’s software, which may need to be done by the dealership or authorized technician. Worst case scenario you will have to replace the camera and its control module. For more help with diagnostics, contact our service department for an inspection.

My car shows the check engine light, the computer showed code P0455, and it shakes and vibrates at stops and during acceleration.
ANSWER : First, remove and reinstall the gas cap, clear the code P0455, and drive the vehicle for a few days and see if the code comes back.
If the code comes back on, then either the gas cap needs replaced or there is a evaporative leak around the fuel tank area. Check all of the fuel lines, hoses, and tubes and see if there is any wet areas.
If all of the lines, hoses, and tubes are tight, then the purge valve maybe damaged and leaking. If you need further assistance with your emission system leak detection, then seek out a professional, such as one from Your Mechanic, to help you.

Cannot pump gas except a small amount it will cut off like it is full. Gauge will show half full or full. Later it will show empty
ANSWER : There are a lot of things that can cause what you’ve described: a faulty fuel sending unit in the tank and the tank is actually full, a stick ORVR valve not allowing pressure in the tank to leave when fueling, or a saturated charcoal canister that cannot let the excess pressure in the tank escape. Are you able to fill an additional $10 in fuel after it cuts off? If so, then this may be a malfunction in the evaporative emission system not allowing pressure to leave the fuel tank when filling. If it cannot take more than $10 at all, then the fuel tank may be full and the sending unit is failing and providing a false reading. I strongly suggest acquiring a qualified technician to perform an inspection due to the volatility of fuel. A certified professional from YourMechanic can come to your car’s location to inspect the fuel problem and advise you on repairs.

My car shows the Check Engine Light and DPF lights and coil light on the dashboard. What action should I take?
ANSWER : Hi. The EGR valve needs to be replaced and the passages to the EGR need to be cleaned. The EGR location is very tricky to get to so you may need a professional technician (such as one from YourMechanic) who can complete this repair. The diesel particulate filter (DPF) filter should also be replaced and the housing for the filter should be inspected for damage due to the people stealing your filter.
