DTC P0463 - Fuel Level Sensor Circuit High Input
The fuel level sensor (sender) is located in the fuel tank usually integral to the fuel pump module. Usually they cannot be replaced without replacing the fuel pump module, though there are exceptions. There is a float attached to an arm that travels along a resistor which is grounded to the tank, frame or has a dedicated ground circuit. Voltage is supplied to the sender and the ground path changes according to fuel level. How much voltage depends on the system but 5 volts isn't uncommon.

As the fuel level changes, the float moves the arm and changes the resistance to ground which varies the voltage signal. This signal may travel to a fuel pump computer module or directly to the instrument cluster module. Depending on the system, the fuel pump computer module may only monitor the resistance to ground and then relay the fuel level information to the instrument panel. If the fuel level signal to the fuel pump module (or instrument cluster module or PCM (powertrain control module)) goes above 5 volts for a specific amount of time, then the module that is monitoring the fuel level circuit will record this fault code.

Symptoms of a P0463 DTC may include:
Mil (Malfunction indicator lamp) illumination
Fuel level gauge may fluctuate abnormally or read empty or full
Fuel light may illuminate and sound alarm

Potential causes of a P0463 code include:
The signal circuit to the fuel sender is open or shorted to B+ (Battery voltage)
The ground circuit is open, or ground path may have high resistance due to rust or missing ground ******** fuel tank
Damage to the fuel tank could cause problem in fuel level circuit
There's an open in the fuel lever sensor's resistor to ground
Possibly faulty instrument cluster
Less likely is the possibility that the PCM, BCM, or Fuel pump computer module has failed

Possible Solutions:
Fuel pump senders normally last the life of the fuel pump. So if you have this code present, do a visual inspection of the fuel tank and wiring harness. Look for damage to the tank indicating impact that may have damaged the fuel pump or sender. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector. Repair as needed. Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness. If not, repair the open or short in the wiring.

Doing a voltage drop test on the ground circuit can determine if there is a high resistance path in the ground circuit. You can perform this by using a voltmeter and connecting one lead to the battery ground post and the other to the fuel level sensor ground at the tank. Turn the key on (preferably the engine should be running). Ideally it should be 100 millivolts or less (.1 volts). Anything close to 1 volt indicates a current problem or a developing problem. Repair/clean the fuel level sensor ground as needed. It's not impossible that the instrument cluster has failed internally or on the printed circuit board (if applicable). These are very difficult for the layman to test. But if you have access to a wiring diagram you may be able to remove the cluster and see the damaged circuit if it's located on the printed circuit board, but otherwise you'll need a scan tool that will communicate with the instrument cluster.

A simple way to test the fuel level circuit is to provide a good ground to the fuel level sensor at the fuel tank connector. With the key on the fuel gauge should go to one extreme or the other. Removing the ground path completely should cause the gauge to do the opposite. If the gauge responds, you know the wiring that supplies voltage and ground to the fuel level sensor is good and that the instrument cluster is likely okay. The likely suspect would be the fuel level sensor itself. The fuel tank may need removal to gain access to the fuel pump module in the tank. A PCM or BCM (Body control module) failure isn't impossible but highly unlikely. Don't suspect this first.

Also, DTC P0462 - Fuel Level Sensor Circuit Low Input, same test to diagnosys.

DTC P0700 are transmission codes. Apparently something went wrong and the computer detected a difference in the position of the shift linkage and what gear the vehicle was in. You should be able to drive the vehicle during this period of time. The only thing you should be aware of is to make sure you don't feel any transmission slipage, otherwise you are fine until your appointment.

DTC P02610 - Control Module Long Term Memory Performance
This code is often set because the battery went dead and you tried to start it. There is a calibration update to correct this and it will not require a new ECM. See you dealer for the calibration update.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: Check engine light error code 480

P0480 Cooling Fan I Control Circuit Malfunction
-----------------------------

Chrysler has issued a TSB (#18-004-07)containing the fix for an inoperative cooling fan on 2005-06 Caravans and Town & Country vans with the 3.3L or 3.8L engines. The problem usually occurs after driving in heavy snow conditions where snow and ice form at the bottom of the fan shroud and block the fan blade. This condition also sets a P0480 code in the PCM. The fix requires a PCM reflash. If you have an inoperative cooling fan or a P0480 code, check the version label attached to the PCM. If a software update has not been performed since this TSB’s issue date of January 24, 2007, you should have the update performed before you start replacing any parts.

SOURCE: po700 and p1776

P0700 is EATX code present. It simply means that the engine computer has noticed that the transmission computer has a dtc in it. This causes the Pcm (engine computer) to turn the check engine light on. You will need to have the TCM (trans computer) checked for codes to know what to diagnose.

error code P1776 - Replace rear solenoid switch

Likely both related The P1776 probably kicked off the P0700 notification.

Hope that helps! Happy Motoring!

What is code po700


It means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module

Dodge 2002 stratus 2.4liter codes po016 p0700 ,po562,what could these mean & how do you fix


lets start with po562, this is a transmission code with low voltage reading at trans solenoids, for this code test your battery and alternator,
the next code po700, this code is to tell you that there is a transmission code stored in the transmission module, which could be the po700. but sccanning the trans module may be a good idea to check for other codes, i assume at this point you are having transmission problems? as far as these codes i would check all fuses and connectors going to transaxle(transmission). you may have internal problems, as we know these chrysler transmissions are junk but you may have bad connection or bad wire to transaxle controller.
last code po016 this code i would check first, i have worked on a few of these that had po016 which means crank and cam correlation . this means the crank and cam are not aligned meaning worn chain , these 2.7 engine... or cam gear spun. testing this ,you will need to know about car repair or you could damage the engine if it isnt already.

Honda accord 2001 code PO700


P0700 HONDA Description The Transmission Control Module (TCM) monitors the malfunction of sensors and actuators relating to transmission control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission control.

PO700 PO740, check engine light on. Run a test on


PO700 is a code telling you there are codes in the TCM of some late model cars where the Transmission control module has lost connection to the PCM the vehicals main computer , And basically it happens when the TCM has a issue within itself or the transmission that sets a code and it sends a request for the PCM to illuminate the SES or CHECK engine light.
PO740 is a chrystler specific code that involves your Tourqe Converter Clutch Circuit (specifically The TCC solenoid) this code if not repaired quickly could cause major transmission problems....slipping out of gear....not shifting from first to second properly and just all around trans problems...eventually leading to no shifting at all...I highly recommend fixing it soon.
