07 Hyundai Santa Fe fuel sensor code 2068 circuit B high. Would that be the sensor on the right side?


P0463 Hyundai - Fuel Level Sensor 'A' Circuit High Input
P0464 Hyundai - Fuel Level Sensor 'A' Circuit Intermittent
P0463 Hyundai - Fuel Level Sensor 'B' Circuit High Input
Possible causes
- Faulty fuel level sensor
- Fuel level sensor harness is open or shorted
- Fuel level sensor circuit poor electrical connection
The fuel level sensor of Hyundai Santa Fe is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

1997 Cadillac Eldorado fuel gauge not reading fuel level correctly


Did you test before replacing ? Do you know how it work's ?

Fuel Level
The body control module (PZM) monitors the fuel level sender input in order to determine the current fuel level. The PZM filters the input and sends a message via the Class 2 serial data line. The IPC receives this message and displays the current fuel level. The fuel level is sent from the PZM to the IPC at changes of 0.5 L (0.02 gal) or on the request of the IPC, with a resolution of 0.04 L (0.01 gal).
• For the digital IPC, when the fuel level is above 18.5 gal, the IPC displays an F. For readings between 18.5-2.5 gal, whole gallon/liter numbers are displayed. When the fuel level reaches 3.0 gal the message FUEL LEVEL LOW is displayed on the driver message center. When the fuel level reaches 2.5 gal, the IPC displays an E. When the fuel level is 1.2 gal or below the IPC displays a flashing E.
• For the analog IPC, when the fuel level is above 18.5 gal, the fuel gauge pointer is on F. When the fuel level is below 2.5 gal the fuel gauge pointer moves to E. When the fuel level is below 3.0 gal the IPC displays a FUEL LEVEL LOW message.
If the updates are not received or a communication error is detected, the IPC performs the following actions:
• For the digital IPC, the fuel gauge is dashed.
• For the analog IPC, the fuel gauge pointer moves to E.

Fuel Gage Inaccurate or Inoperative
Circuit Description
The IPC monitors the fuel level sent by the PZM through the class 2 serial data line. The IPC software controls one of the following two gauge types:
• A digital gauge consisting if a two-digit numeric seven-segment display
• An analog gauge consisting of a needle pointer.
The IPC interpolates and scales the fuel level information that the IPC receives from the PZM.
When you operate the vehicle in diagnostic mode, either in the vehicle diagnostic system or with a scan tool connected, the fuel signal supplied to the IPC is not filtered by the PZM. The unfiltered fuel signal causes the IPC to show real time readings and may be mistaken as an erratic fuel level display.
Diagnostic Aids
Connect a scan tool to the DLC.

I had an diagnostic test done on my 2007 kia optima and it read p0170 fuel trim (bank1) what does this mean


code p0170 refers to two problems
fuel trim bank 1 --malfunction
heated oxygen sensor(HO2S) 3 bank1 --circuit malfunction
for the first error==causes-- intake leak --AIR system---fuel pressure /pump---injectors--EVAP canister purge valve---HO2S
for the second one ===causes=--wiring--HO2S---ECM
The explanation of fuel trim is long winded and you may get some typo errors but I think that you will get the idea
short and long term fuel trim refers to the strategy used to reduce exhaust emissions after a basic computation of injector period, using engine load as a major parameter
both front and rear oxygen sensors signals are used to fine tune the air/fuel mixture by increasing or decreasing the injection period =/- 25% above or below the basic level
any fault requiring a correction beyond this level will result in a fault code being logged ( in this case p0170)
the fuel trim will oscillate the injection period =/- 5% above or below the mean level level A
manufacturing and in-service tolerances of load sensors (MAP,MAF, VAF) and injectors in particular and faults such as intake leaks( vacuum hoses from vent controls and transmission) will affect the air/fuel mixture and cause the trim to compensate
an air intake leak for instance would increase the injection period increasing for example to 115-125%. this level will also oscillate +/- as before level B
this new short term fuel trim level will be stored in the ECM if it is established as a new basic mixture level
It will become a long term fuel trim correction and results in the correct mixture level immediately after starting, even when the HO2S has had sufficient time to heat up
Now having some idea of what trim is, you will see the necessity of repairing any problem sensors ,air leaks ,vacuum leaks
You will also probably understand the reason of why an engine after running short runs ( city driving) feels that it gets more power and better economy after 1/2 hour on the open highway
The ECM resets the trim to the new load power settings and that becomes the new trim

How to remove fuel level float assembly from `47 16 hp hurricane without first removing the fuel tank.


Sir, I do not believe you will be able to install the Fuel Level Sending Unit without removing the tank. The gasket is difficult to place accurately and visibility of your work is limited opening the possibility of errors. I HIGHLY recommend that you do not attempt to replace the sender assembly while the tank is still in it. Thank You for your time and for using FixYa.com I hope your on your way soon! 9_19_2014_1_47_35_pm.jpg

What is causing the code p 0464


exactly that.

- Faulty fuel level sensor
- Fuel level sensor harness is open or shorted
- Fuel level sensor circuit poor electrical connection
the error mean the signal is out of range, or illegal .
corrosion at the tank connector , tops list.

Getting error code P0181. Can I fix this or it requires a mechanic?


you dont need to drop the tank usually u can take the fuel pump out from under the rear seat there should be a plate that you unscrew and wala there is your pump and that code is a fuel tank tempetature sensor curcuit and it requires a new fuel pump to stop it from coming on i know because i just had to replace mine and now no check engine light lol

Error code P1627


The fuel level sending unit in the fuel pump. That float thing attached to it. That is what the code is and also why the fuel gauge does not work.
