Question about Cars & Trucks
Hi Candice, .How does it run ? P0305 is a misfire code for cylinder #5, P0106 The manifold absolute pressure (MAP) sensor responds to pressure changes in the intake manifold. The pressure changes occur based on the engine load. The MAP sensor has the following circuits:
5-volt reference circuit
• Low reference circuit
• MAP sensor signal circuit
DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
The EBCM detects an erratic rear wheel speed signal for 105 milliseconds.
DTC C0265 EBCM Motor Relay Circuit
Thoroughly inspect connections and circuitry that may cause an intermittent malfunction.
• DTC C0241 EBCM Control Valve Circuit
• DTC C0242 EBCM Control Valve Circuit
• DTC C0243 EBCM Control Valve Circuit
• DTC C0244 EBCM Control Valve Circuit
• DTC C0245 EBCM Control Valve Circuit
• DTC C0246 EBCM Control Valve Circuit
• DTC C0247 EBCM Control Valve Circuit
• DTC C0248 EBCM Control Valve Circuit
• DTC C0251 EBCM Control Valve Circuit
• DTC C0252 EBCM Control Valve Circuit
• DTC C0253 EBCM Control Valve Circuit
Sure looks like the ( EBCM ) Electronic Brake Control Module needs to be replaced .All these codes mean The EBCM detects an internal malfunction. Is the abs light on ?

PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.
On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.
Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.
Hope this helps...

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
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.
