i have obd code 2066 which sensor is the b sensor 2015 Chevrolet Equinox

i have code po2066 and no fuel reading

My car has 40012 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello – this problem code is from the RIGHT side (passenger side) fuel level sensor. Most often this means a dirty or malfunctioning fuel gauge sensor on that side, and the instrument cluster reverts to "Empty" to get your attention. Cleaning or replacing the sensor, and clearing the code, will restore the fuel gauge to proper operation. I recommend a fuel sensor replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Code P2066 is for a performance problem with the fuel level sensor B. Vehicles that use this second sensor may also have a transfer pump that may be failing and will cause the unequal fuel levels in the two sides of the fuel tank.
These fuel level sensors are located in the gas tank and are located on the fuel sending unit. Replacing these sensors requires gaining access to the fuel tank and is a job best left for professionals.
Pressure Sensor: The most common type of pressure sensors used for fuel level measurements is hydrostatic type sensor.
OBD-II Code P018C is defined as a Fuel Pressure Sensor “B” Circuit Low. The Fuel Pressure Sensor monitors the fuel pressure in the fuel system. The Fuel Pump Control Module uses this information to adjust the fuel pump`s on time as needed.
The vehicle speed sensor B reads the wheel speed sensor for the anti-lock brake system (ABS). There are several components that are impacted by the operation of the vehicle speed sensor.
P0463 is a generic OBD-II diagnostic trouble code (DTC) defined as “Fuel Level Sensor Circuit High Input.” Your vehicle`s powertrain control module (PCM) or Engine Control Module (ECM) monitors the fuel level circuit to determine the amount of gas in the fuel tank and manage fuel usage and economy.
The fuel rail sensor, commonly referred to as the fuel pressure sensor, is an engine management component that is commonly found on diesel, and some gasoline injected vehicles. It is a part of vehicle`s fuel system and designed to monitor the fuel pressure that is present at the fuel rail.
Some sensors change how the engine behaves when it receives information from the control module. The idle air sensor, coolant temperature sensor and EGR sensor all change things within the engine and fuel delivery system.
A fuel gauge that reads full or empty all the time, or has a needle that moves erratically, could be the result of a faulty sender unit or fuel gauge itself.
Press and hold the “Trip/Odo” button and turn the car back on. While you`re holding the button, turn the key back to the “ON” position. Hold the button down for another 2 seconds after the car`s back on, then release.
Fuel Pump. Fuel injection systems operate at high fuel pressures, typically in the 40-60 psi range, or higher for direct injection.
The fuel pressure sensor for low pressure is installed in the feed line to the high pressure pump and sends its signal to the engine control unit.
The throttle/pedal position sensor “B” is used along with other sensors to communicate to the engine control module (ECM) what the position of the throttle is and how far depressed the gas pedal is. This is used to calculate a variety of things such as throttle percentage and engine load.
This code is specific to sensor “B,” which, in general, is the exhaust camshaft sensor.
The following are the eight key sensors of the car: air flow sensor, intake air temperature sensor, throttle position sensor, water temperature sensor, camshaft position sensor, crank position sensor, knock sensor and oxygen sensor.
The “pre-cat sensor” regulates fuel supply, while the downstream sensor measures the efficiency of the catalytic converter. O2 sensors can typically be categorized as either a narrow band or wide band sensor.
An air-fuel ratio meter monitors the air–fuel ratio of an internal combustion engine. Also called air–fuel ratio gauge, air–fuel meter, or air–fuel gauge, it reads the voltage output of an oxygen sensor, sometimes also called AFR sensor or lambda sensor.
They are two different things. A regulator regulates fuel pressure to stay within a certain range (usually 50-60 psi) and a sensor reads the fuel system pressure for the ECU to monitor and adapt to whatever fuel pressure the sensor is reading.
Driving without a working fuel gauge is illegal in most states. It can also leave you stranded, and you may even damage your car. If you know your instrument cluster is faulty, it`s time to call ISS Automotive.
Usually, you will get anywhere from three to five years out of your air fuel ratio sensor. Signs that your air fuel ratio sensor needs to be replaced include: Poor fuel economy. Sluggish performance.
Bad Fuel Pump, Fuel Pressure Sensor Can Trigger `Check Engine` Light, P0087 Code. Your car`s “Check Engine” or “Service Engine Soon” light can flash on for more than 1,400 different reasons.
How do I reset my Chevy fuel gauge? There are two ways to reset your Chevy fuel gauge. For newer vehicles equipped with the instrument panel cluster, simply push and hold the button on the end of the turn signal lever for about 10 seconds. You can also try disconnecting the positive battery cable for about 10 seconds.
This analysis is done by gauging the fuel pressure and the fuel delivery rate. To get the right results, you need the OBD-II code reader to gauge the real-time engine data. You then connect the diagnostic reader to the car and read the engine parameters. When that is done, select the fuel delivery system option.
P0087 is a diagnostic trouble code (DTC) that stands for “Fuel Rail/System Pressure Too Low” and indicates a fault within the fuel delivery system. It is usually triggered by the Powertrain Control Module (PCM) when it detects the pressure inside the fuel rail or the fuel system to be below the minimum levels.

My code reader says I have a bad mass air flow sensor ans crank shat sensor test drive ran better shut off & engine Lt. Same code
ANSWER : Hi there. The problem you are describing, sounds like you may have a poor connection in the connector at the mass airflow sensor. Although, sometimes aftermarket parts do not perform as well as factory (OEM) parts. Check for corrosion and/or wide spacing in the terminal ends. Compare the terminal ends in the connector using a flashlight to see better. The terminals can be tightened. If you are not comfortable with doing that, a replacement pigtail (connector) is available. You vehicle may require further diagnosis performed with a scanner that provides parameters that can be viewed as the fault occurs. If that is the case, I recommend having your vehicle’s electrical circuits inspected in order to pinpoint the underlying fault.

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.

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. Your Mechanic has several available technicians that can assist you with a check engine light inspection.

I had a p0405 get code replaced egr valve, map sensor,mad sensor, and PCv valve just to be safe but still getting the code why?
ANSWER : The code P0405 and a rough idle is most likely due to carbon getting into the EGR pintle. This will hold the EGR open. When you are getting the rough idle you should shut off engine and remove EGR valve. Check to see if carbon is holding the pintle open. If it is then you will have to remove the carbon from the pintle. Then try and clean out the EGR passages by scrapping them using a round wire brush. Afterwards, start the engine for a few seconds with valve removed to blow out loose carbon. You should then spray a small amount of carbon cleaner into the passages to dissolve the carbon. Lastly, reinstall the EGR and reset the light and codes.

If you’d like assistance with this, consider YourMechanic, as a certified professional can come to the vehicles locations to perform these checks and properly diagnose your Check Engine Light.

Service engine warning, MAF code and O2 sensor code, along with check suspension light are turned on
ANSWER : Hello, it sounds like you have quite a few things going on. I am going to do my best to break them down for you.

First if the engine is very loud when idling and the belt has already been replaced, there may be an issue with the tensioner or idler pulley.
Next, the Navigator is known for needing service to the air suspension system as it gets up in miles, the most common causes of these are the air struts themselves have failed, or one of the air lines has a leak.
Lastly, if the O2 sensor and MAF are continually coming back after the sensors have been replaced, the most common cause would be either an exhaust leak or a vacuum leak.

Qualified technicians such as the ones at YourMechanic will be able to diagnose these issues and recommend the best path to repair, starting with a diagnosis of your warning lights.

Diagnostic code read o2 sensor bad, replaced o2 sensor, cleared code but engine light came back on, is it caused by bad air filter
ANSWER : Hello there. Typically jump starting a vehicle doesn’t trigger an OBD-II error code. However, one of the most common misdiagnosis issues with the P-2270 is replacing the O2 sensor before diagnosing if there are any exhaust leaks. Obviously, you’ll want to check for the exhaust leaks first, repair the damaged component, and then clear the codes before scanning the vehicle again. Sometimes the electrical harness attached to the O2 sensor is damaged or dirty which will also trigger this error code. The noise and vibration may be an indicator of a loose exhaust pipe, which may be the source of the error code staying on. If you need any help, have a technician from YourMechanic come to your home or office to diagnose your Check Engine Light and make the necessary repairs.

Car won’t start … codes fuel level sensor b and fuel level sensor a
ANSWER : Hi there:

You might want to have a professional mechanic come to your location and complete a check engine light inspection, so they can download all of the error codes. The fuel level sensor a and b code can be triggered by more than 10 individual sensors or mechanical components. By competing this inspection, they should be able to determine what is faulty and causing your 300 to not start.
