Question about 2005 Ford Mustang

1 Answer

My engine light came on in my 2005 Ford Mustang GT and the code reads: Circuit A, Cam Shaft Position Sensor. Then my RPM gauge worked then stopped working then worked then not. I was driving my car and the stereo and AC quit working then restarted again. When I restarted my car, it wanted to crank but it started clicking and I had to get a jump. Had car tested at Auto Zone and they said battery and starter are fine and the altenator was loosing power. We rebuilt the altenator and it didn't fix the problem. Could it be the computer or the wiring harness??

SOURCE: Code: P0340 Cam shaft position

Causes

A code P0340 could mean one or more of the following has happened:

  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed, yes the crank sensor can set this code as well
Possible Solutions

With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

SOURCE: 2005 Ford Mustang. Clicking noise

this problem could have a few causes.
the battery clamps are corroded and need cleaning
a loose wire from the battery
faulty starter relay
a weak starter

I would start by inspecting and cleaning the battery posts and clamps also make sure that the clamps are fully seated on the posts and tighened securely.
check the battery and starter wires for signs of wear, such as torn or burned insulation or frayed wire, near connectors.
If cleaning the connections in the charging / starting system does no good then you might need to replace the wires completely.

you could also remove the starter (disconnect the battery first!) and take it to a local parts store such as Autozone for testing.

as for the excessive engine revs, this could be something as simple as needing to add some of the proper type of automatic transmission fluid. after you get the vehicle starting again you should check the transmission fluid level

original posted @ http://www.allfordmustangs.com/forums/2005-2010-v6-mustang-tech/120748-2005-2008-mustang-auto-transmission-fluid-adding.html

"Basically, the drain plug on the transmission has another plug in the center of it. You add fluid and use it to determine if the fluid is filled as it is connected to a tube in the drain pan. They tell you to pump Mercon V transmission fluid into this connection. You will need to get a hose adapter to scew into the center tap and connect a hand pump or electric pump to the hose fitting. When you think you have added enough, disconnect the hose, if you are underfilled, nothing will come out, if you are overfilled then fluid will come out until it drains down to the proper level. Make sure the car is parked on level ground when you do this or you will not get proper results. When removing the center plug, make sure you hold back on the drain plug with an open end or box wrench, or you may end up removing the drain plug and will drain the entire transmission fluid that is in the pan, rather than just checking to see if it is full."

I like to start with the free or cheap stuff and work my way up to more expensive solutions.

so in summary
1.) check clean and reinstall battery cable clamps

2.) check wires and connections on starter as well as any power distribution blocks or
engine / chassis ground.

3.) take starter to parts store for testing, take the battery as well, most can test or charge your
battery in as little as an hour.


Finally, if none of these solutions remedy the situation then you may need a new alternator or serpentine belt.

hope this helps

You have a open connection somewhere,do you check the fuses especially the fuseable link at the positive battery post how about the power at the ignition switch it hot at all times,your disconnected somehow you might have to make a jumper wire to find what opened.

SOURCE: 01 mustang gt cranks once

Sounds to me that your starter is gone. There is one thing you can do, try tapping ya starter and then try starting the car. If it starts then you have what is called a dead spot in ya starter. The only fix for this is a new starter. Make sure that you dont have a bad wire going to your starter also. Hope this helps.

Hi Kevin it sounds to me like your solenoid that is attached to your starter motor needs replacing had this with a ford cortina mk 5

The code on my car vw new jetta 2005 its a 2.5 the codes is reading on my car p0322 and code p3081 the reading was took when my epc light came on and my engine light on and i have a oil link i smell r


code p3081 refers to engine temperature too low===causes--allow engine to warm up---cooling system fault
I would check for a thermostat stuck open

code p0322 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor--no signal===causes--wiring---CKP/RPM sensor---ECM

2003 mustang gt will skip when it hits about 1,500 rpm but after that it is fine but you can still feel a little skip in it.


lckydog18
I have a similar symptom. No engine light lite. It can be felt as I accelerate moderately from a standing stop. Then as my engine begins a climb in rpm in seems to hesitate for a brief moment and then continue to increase rpm. Not sure what this is.

Is this the symptom you were identifying?

A p0340 trouble code and i changed the cam position sensor and all 4 o2 sensor's on a 01 ford mustang gt with a 4.6


Code P0340 is a camshaft position sensor CIRCUIT fault. This means it can be a bad sensor, wiring fault (loose connector, short, open), or even a bad PCM. Since you've already changed the camshaft position sensor you've eliminated that possibility. It's time to do some electrical troubleshooting. That, of course, depends upon your skill set for this type of work and equipment (mostly a good dmm and schematics). If you're not equipped for this then you'll likely have to seek assistance from a local shop.

My RPM gage on my mustang saleen isn t working


the tach uses the same fuse as the other gauges, so if the other gauges have no problem then the tach is defective, Ford does not really repair these we just replace them.
