I had a PO463 code on my '06 Jeep Cherokee. The gas gauge went from full to empty and low fuel light along with the check engine light came on when I started the car. Instead of rushing to have it fixed I filled the car and set my trip meter to zero. After about a week I noticed that the gauge would stay at a certain level before going to full and then drop to empty.This morning the gauge stayed at the 1/2 mark but the check engine light was on. I filled the car with gas and when I started the car the gauge read full and the light was off. I drove about 20 miles with no more problems. What happened? We had a temp of below zero weather for a few days, which isn't normal for my area, and I think water in the fuel froze on the level switch and then after several days it thawed. Saved myself 6-800 dollars waiting a while.

If you live in a cold weather area, below zero, water in the fuel can freeze and cause the fuel level sensor to send a false signal or no signal. I fiiled the car, set my trip miles and waited for warmer weather. I got to about a half tank, according to the trip miles, and filled the tank again. Fuel gauge read correctly, the check engine light went off. All is good. Saved me 6-800 dollars for a replacement of the level sensor.

Hello. There are several possible causes of your issue. Replacing parts to find the root cause is an expensive route for you. Why not drive to an AAMCO and have them give you the free computer scan which may pinpoint the issue. On the otherhand, nothing may show up. To prevent running out of fuel be sure to maintain a log of fuel use. Good luck. Joe

Po463 code on a 3.9l dodge dakota

The P0463 code (Fuel Level Sensor Circuit High Voltage) means that your fuel guage circuit is open. To fix the fuel guage, the tank must come out to replace the sending unit. Personally I wouldn't worry about it too much. Use your trip guage and fill up after 200/250 miles. You'll never run out.

Possible causes - Fuel level sensor circuit harness is open or shorted
- Fuel level sensor circuit poor electrical connection
- Faulty fuel level sensor in fuel tank (most common cause) P0463 Description The fuel level sensor 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

My 2004 nissan sentra will not start, just turns over.obd code po455,po183 and po463 not sure what to check. I tried gas cap, took gas line off and turned car over but no fuel, it my be my fuel pump but...

P0183 = Fuel temperature sensor A circuit, high input

P0455 = evaporative emission (EVAP) control system leak detected (no purge flow or large leak)

P0463 = fuel level sensor circuit, high input.

Check to see if the charcoal (evap) canister is full of fuel. If so, empty it. Check for a faulty canister vent valve. Check for a short to ground in wiring to fuel temp sensor and fuel level sensor.

P0138 - O2 Sensor Circuit High Voltage Bank 1 Sensor 2

The rear heated oxygen sensor (or sensor 2), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2. This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Under normal conditions the heated oxygen sensor 2 is not used for engine control operation.

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Rear heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 2 usually takes care of the problem

P0141 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Rear heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 2 usually takes care of the problem

P0463 - Fuel Level Sensor Circuit High Input

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the ECM or PCM, It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

Causes:
- Fuel level sensor circuit harness or connectors is open or shorted
- Fuel level sensor may be faulty

Solutions:
Replaced fuel level sensor.
